PERMANENT MAGNET DC SERVOMOTORS -
USER INFORMATION
a shaft seal (option WO1) is fitted and the fixing boltholes are sealed.
Blower ventilated motors are protected to the following degrees:The MT30 blower ventilated range is protected to IP20. The MT40
and 52 blower ventilated ranges are protected to IP10.
E.C. DIRECTIVES
There are 3 main directives that effect applications incorporating
servomotors.
Machinery Directive 89/392/EEC
This directive applies to complete machines.
In accordance with the directive, SEM provides a Certificate of Incorporation
which includes installation instructions and general service guidelines in
different languages.
Low Voltage Directive 73/23/EEC
This directive applies to electrical equipment for use with a DC voltage of
75V to l500V and AC voltage of 50V to 1000V.
SEM DC servomotors in the ranges MT22, MT30, MT40 and MT52 conform
to the EC directive.
A certificate of conformity is available from SEM sales on request.
EMCDirective (Electro Magnetic Compatibility) 89/336/EEC.
This directive applies to products or appliances with an intrinsic function for
the end user in which:
1. They contain electrical/electronic systems liable to cause an electro
magnetic disturbance.
2. They contain electrical/electronic systems which may have their
performance affected by an electromagnetic disturbance.
SEM can provide data sheets outlining the EMC characteristics of a standard
SEM DC servomotor and giving advice on cable screening and other related
subjects.
SEM will be pleased to discuss any EMC related problem encountered by
customers incorporating SEM DC servomotors into such products or
appliances which are governed by the EMC directive.
Mounting of Motors
Where a toothed belt drive is proposed the motors should be face
or flange mounted to an angle bracket, or similar, as close as
possible to the line of action of the drive. The motor pulley should
be positioned as close as possible to the mounting face and the
pulley diameter chosen to maintain dynamic shaft loading within the
limits indicated on the loading graphs. Particular attention must be
given to tensioning of drive belts, with reference to belt
manufacturers instructions, so that unnecessarily high shaft loads
are avoided on installation.
When a motor is close coupled to a reduction gearbox, it is strongly
recommended that to withstand the reaction of high output torques,
the complete unit is fitted to the final product by attachment at the
gearbox, not by foot mounting the motor.
A foot mounting option is available on SEM servomotors but this
should generally be restricted to in-line drives where high lateral
moments can be avoided.
Electrical Connections
A diagram plate is fitted under the terminal box lid. (Or attached to
each motor in the case of motors fitted with an MS connector).
IMPORTANT - When the motor is to be used in a closed loop
circuit, the polarity of the tacho relative to the rotation of the motor
must be as diagram plate. Incorrect polarity could cause the motor
to over-speed. Commutator flashover and field demagnetisation
could occur.

GENERAL DESCRIPTION
This range of DC Servomotors has been specially designed to meet
the application requirements of Machine Tools, Transfer Lines,
Robotics and the like. They provide a high torque to inertia ratio,
giving fast acceleration and rapid dynamic response. Our data
sheets give the full specification.
The motors are suitable for most servo and variable speed
applications and are compatible with most drives available. It must
be remembered that all SEM data on its range of Servomotors
assumes unity Form Factor (i.e. pure DC) and that derating of the
motor may be necessary when supplied from a power source
exceeding unity Form Factor.
SEM DC brushed servomotors are rated for the temperature rises
specified in NEMA standard MG1 part 12.63.2.
Thermal Protection
MT30, 40 and 52. Servomotors have fitted as standard equipment a
thermal protector to monitor temperature and protect the armature
winding. The protector contacts are of the normally closed type and
should be connected in such a manner as to shut down the motor
controller when the contacts open.
Under continuous full Load conditions the motor body can be
expected to reach a maximum temperature of 100Cº before the trip
operates. IMPORTANT - The protector can only be relied upon to
sense over temperature produced by long term overload operation
of the motor. As the motor has a large thermal mass, short duration
high currents will not be sensed by the thermal overload and could
result in damage to the motor. The overload is not capable of
switching motor line currents and must be used only in the motor
drive circuitry.
Receiving & Storage
On receipt the motors should be inspected. Any damage found
should be reported immediately to SEM and the carrier.
The shaft and flange have been coated with a rust inhibitor; this can
be removed with a suitable solvent.
If the motors are not to be put into service immediately they should
be stored in a clean dry location, and should be run on a light load
or no load prior to being put in service. This is to clean any possible
filming that may occur due to oxidation on the commutators .
Maintenance & Servicing
All routine maintenance can be carried out by the user, but it is
recommended that, for major repairs and reconditioning, the motor
be sent to an approved motor repair specialist or returned to SEM.
If the motor is to be dismantled, any feedback package fitted to the
rear shaft, the tachometer armature, and any electrical connections
must be removed first.
Nameplate Information
When contacting SEM regarding a motor, the type and serial
number should be quoted.
Location/Accessibility
The motors should be installed such that they are readily accessible
for routine inspection and maintenance.
Brushes - Motor
It is recommended that the motor brushes in the commutator end
housing be inspected for wear every 500 hours of operation or at
intervals which are found satisfactory after a usage pattern has
been established.The brushes, under normal usage, should give
4,000 hours of life on a unity form factor drive. When the brush has
worn to 7mm it should be replaced. Only recommended spares
obtainable from SEM should be fitted, as brush grade and spring
Environmental Protection
SEM Servomotors are protected against ingress of fluid and dust to
the following degrees:The MT22 range is protected to IP65 (IP64 at drive end shaft seal).
The MT30, 40 and 52 ranges are protected to IP44/65 as
standard,IP54 is available as an option. This increases to IP64/65 when
2
tension have been specially selected for the motors. Brushes
should move freely in their holders and care should be taken to
ensure that good contact is made between the brush tag and the
brush holder. When inspecting for carbon brush wear, we
recommend that any carbon brush dust is cleared from the motor
by removal of all the brushes from their holders, and blowing clean,
dry air into one of the brush holders.
IMPORTANT - It must be noted that commutation and brush wear
progressively deteriorate as the commutation limit is approached. If
required acceleration or deceleration results in operation regularly
close to the limit brushlife will be considerably reduced.
Blower Options
The motor of the blower type used by SEM is sealed for life and
should require no maintenance under normal usage.
The inlet filter should be cleaned at regular intervals, as a dirty filter
would restrict the airflow through the servomotor, causing
overheating. When dirty this filter can be regenerated by
washing in warm water with added detergent and drying.
Mechanical
It is recommended that a general inspection be made at regular
intervals to check all bolts, nuts, couplings, etc. to make sure they
have not worked loose, and thus prevent serious damage.
Commutator
The normal colour of the commutator is dark brown: do not remove
this film unless commutator is in poor condition. Minor cleaning of the
commutator can be carried out by removing one brush and inserting
a glass fibre cleaning stick of brush cross sectional area, and rotating
the armature; remove other brushes and blow out after cleaning.
End Cover Alignments
The proper orientation of the motor end cover to the motor body is
necessary for optimum performance of the motor; an alignment
mark should be scribed over end housing and adjacent shell before
dismantling, so machine can be re-assembled with correct
orientation.
The drive end cover is pinned to the shell. The developed torque of
the motor is transmitted by the pins and associated friction between
D.E. cover and shell.(Not applicable to MT22)
The commutator end housing is not pinned, as under normal
conditions no torque is transmitted.
Recommended Stand By Replacement Parts List per motor.
Permanent Magnet Field
The permanent magnets used in our Servomotors are made from a
highly coercive ferrite material and are designed to withstand high
demagnetising fields. The field will be demagnetised if a
momentary current exceeds the peak current rating given on the
data sheet. Special note should be made when using thyristor drives.
The permanent magnet field is open circuit stabilised and the motor
armature removal will not affect subsequent motor performance.
On blower ventilated machines, despite the inlet filter, there may be
a danger that metal particles and foreign matter may enter the air
outlet holes by attraction of the permanent magnets. Care must be
taken with ventilated machines.
Should the magnets become demagnetised for any reason the
machine must be returned to SEM for re-magnetising.

Note: When ordering replacement parts the motor Serial No.
stamped on Nameplate must be quoted, along with the Type No. so
that proper selection of parts can be made.
Bearings
All Servomotors are fitted with single row radial ball bearings,
double shielded and permanently lubricated and under normal
conditions require no maintenance.
If the commutator end bearing is to be removed, care should be
taken so as not to damage or distort the rear shaft extension or
shaft pin, as these must run to close tolerances.
Fault Finding
Note: Trouble which at first appears to be with the motor may in
many cases lie outside the motor
PROBLEM
Tachometer
The tachometer fits over the main shaft and has a permanent magnet
field. This device is a precision instrument and must be treated with
care. Foreign matter must not be allowed to enter this area.
The brushes and commutator should be maintained in the same
manner as the motor parts.
It is essential that the undercutting is maintained free from mica and
copper swarf and the commutator surface is free of burrs to keep
the ripple performance within tolerance.
When re-assembling brush ring to motor, note alignment mark to
retain correct orientation of parts for optimum performance.

Holding Brake Options
A fail safe brake is available as a standard option.
The brake is primarily a holding brake. For example:- to hold a
vertical feed axis under a no voltage condition, however, it can also
in some applications be used for emergency stopping.
The brake is located in front of the armature, the stationary body is
built into the drive end cover.
The brake fitted is of the ‘‘Springset’’ fail to safe type.
The brake should be connected so that when the motor is started
the brake coil is energised, thus releasing the brake. Under normal
operating conditions no maintenance is required other than making
sure the armature and stationary plates are kept free from foreign
matter. Ratings are as follows:Brake Holding

s Motor Performance data is on the basis of a pure D.C. i.e. unity system form factor supply.
Appropriate performance derating is necessary when using a supply with a system form factor
greater than unity.
s Commutation Curves opposite and peak torque are based on the peak value of the current
wave form. For a form factor greater than unity the maximum torque permitted will be lower than
that detailed on the performance curves. IMPORTANT The commutation curves are based on a
load inertia equal to the motor inertia. Advice should be taken in the event the load inertia is
greater than the motor inertia.

s Motor Performance data is on the basis of a pure D.C. i.e. unity system form factor supply.
Appropriate performance derating is necessary when using a supply with a system form factor
greater than unity.
s Commutation Curves opposite and peak torque are based on the peak value of the current
wave form. For a form factor greater than unity the maximum torque permitted will be lower than
that detailed on the performance curves. IMPORTANT The commutation curves are based on a
load inertia equal to the motor inertia. Advice should be taken in the event the load inertia is
greater than the motor inertia.

s Motor Performance data is on the basis of a pure D.C. i.e. unity system form factor supply.
Appropriate performance derating is necessary when using a supply with a system form factor
greater than unity.
s Commutation Curves opposite and peak torque are based on the peak value of the current
wave form. For a form factor greater than unity the maximum torque permitted will be lower than
that detailed on the performance curves. IMPORTANT The commutation curves are based on a
load inertia equal to the motor inertia. Advice should be taken in the event the load inertia is
greater than the motor inertia.
q Heatsink Ratings Torque ratings shown in brackets (opposite top right) are correct for motors
when fitted to a heatsink size (300mm x 300mm x 12mm)

s Motor Performance data is on the basis of a pure D.C. i.e. unity system
form factor supply. Appropriate performance derating is necessary when using
a supply with a system form factor greater than unity.
s Commutation Curves opposite and peak torque are based on the peak
value of the current wave form. For a form factor greater than unity the
maximum torque permitted will be lower than that detailed on the performance
curves. IMPORTANT The commutation curves are based on a load inertia
equal to the motor inertia. Advice should be taken in the event the load inertia
is greater than the motor inertia.

s Motor Performance data is on the basis of a pure D.C. i.e. unity system
form factor supply. Appropriate performance derating is necessary when using
a supply with a system form factor greater than unity.
s Commutation Curves opposite and peak torque are based on the peak
value of the current wave form. For a form factor greater than unity the
maximum torque permitted will be lower than that detailed on the performance
curves. IMPORTANT The commutation curves are based on a load inertia
equal to the motor inertia. Advice should be taken in the event the load inertia
is greater than the motor inertia.
