1.8 Terminal boxes
The location of the terminal box in standard design is on top (view to drive end); on the right or on the left is also
possible. For motors with mounting arrangements IM B6, IM B7, IM B8, IM V5, IM V6 the location of the terminal
box is related to an IM B3 mounting.
8 General specification
The position of the entry openings can be adapted to the existing connection possibilities for most motors by
turning the terminal box by 90°. Please enquire if special accessories should be used (temperature sensors, anticondensation
heating, etc.).
For motors in standard design, the screwed stuffing boxes do not belong to our scope of delivery.
1.9 Belt drive
The data refer only to the normal shaft end at the drive end of IM B3 motors with one speed.
Calculation of radial shaft
load:
FR =
19120 · P · k
D1 · n [N]
FR = radial shaft load in N
P = power in kW
n = speed in min-1
D1 = pulley diameter in m
k = belt tension factor
The belt tension factor depends on the type of belt and is assumed to be approximately:
3...4 for normal flat belt without idle pulley
2...2,5 for normal flat belt with idle pulley
2,2...2,5 for V-belt
Please enquire exact data from the belt manufacturer.
1.10 Vibration behaviour
The vibration severity of electric motors is determined in EN / IEC 60034-14 Mechanical vibration of certain
machines with shaft heights 56 and higher - Measurement, evaluation and limits of vibration severity.
The rotors of the motors are dynamically balanced with half key fitted according to DIN ISO 8821. Other
balancing is avail-able by agreement only.
Our standard motors observe or fall below vibration category A. Motors with ball bearing can be supplied in
vibration category B at extra cost.

1.12 Lubrication and maintenance of bearings
The bearings of standard motors up to frame size 160 (EH1) have permanent lubrication. Bearing grease K3N
according DIN 51 825 is used (e.g. KLÜBER ASONIC GHY72, ESSO UNIREX N3 or similar).
Maintenance-free operating time of motors with permanent lubrication at ambient temperature of 40 °C and
50 Hz mains operation:
§ 2- and 4/2-pole motors 10,000 h
§ 4 and more pole motors 20,000 h, but 4 years at most
General specification 9
From frame size 180 the motors are equipped with lubricator and grease.
First lubrication is made with grease K3N according DIN 51 825 (lithium-based, behaviour in the presence of
water according DIN 51 807 part 1: level 0 or 1).
For motors with lubricator, the regreasing interval and required quantity of grease is indicated on the rating
plate.
For regreasing please observe the operating instructions.
In case of unfavourable conditions (e.g. high ambient temperature, dusty conditions, corrosive atmosphere,
operation by frequency inverter), regreasing should be carried out more frequently.
Lubricating nipples
Flat type lubricating nipple M10x1 according DIN 3404.
1.13 Electrical design
Power
The output of the other rated characteristics specified in this catalogue refers to the following conditions
according to the standard EN / IEC 60034-1:
§ Continuous operation (S1)
§ Frequency 50 Hz
§ Voltage 400 V
§ Ambient temperature of 40 °C
§ Altitude of setup site max. 1000 m absolute
The motors can also be operated in an ambient temperature of up to 80°C and be set up in absolute altitudes of
up to 4000 m. In this case, the output will reduce as shown in the table. Alternatively, a bigger motor might be
required.
For severe operating conditions, e.g. high switching rate, long run-up time or electric braking, a thermal reserve is
necessary, which may require a higher temperature class or the use of a motor with higher rating. In these cases
we recommend further enquiring and specification of the operating conditions.
The motors can furthermore be used in observation of the requirements according to the standard EN /
IEC 60034-1, in areas with limited use zone B (deviations of the voltage of ±10% and of the frequency of ±3%).
When the motors are operated at the limits of the voltage tolerance, the permissible overtemperature of the
stator winding may be exceeded by 10 K.
Rated current
The rated currents specified in the selection tables apply to an operating voltage of 400 V. The conversion to
other operating voltages with equal output and frequency has to be conducted as follows:
Rated voltage (V) 230 380 400 440 500 660 690
Conversion factor x lN 1.74 1.05 1.0 0.91 0.80 0.61 0.58
Rated torque
The motors have a squirrel-cage rotor that is suitable for the direct start-up. The values of the starting torque
and tilting moment can be found in the tables of the operating data.
Rated torque [Nm] = 9550 ·
Rated power [kW]
Rated speed [min-1]
Rated frequency
Motors with windings for 50 Hz can be also operated on 60 Hz mains, when the mains voltage increases
proportionally to the frequency. The relative values for starting and breakaway torque remain nearly unchanged
and slightly increase for the starting current. The rated speed increases by the factor 1.2 and the rated power by
10 General specification
factor 1.15. Should a motor designed for 50 Hz be operated at 60 Hz without the voltage being increased, the
rated power of the motor cannot be increased. Under these operating conditions, the rated speed increases by
factor 1.2. The relative values for starting and breakaway torque are reduced by factor 0.82 and the starting
current by factor 0.9.
Overload capability
At operating temperature three-phase motors are capable of withstanding an overload for 2 minutes (≤ frame
size 112: 15 seconds) with 1.5 times of the rated current at rated voltage. This overload capability complies with
EN /IEC 60034-1 and will not result in excessive temperature rise.
When temperature class F is utilized, motors can be operated continuously with an overload of 12 %. This does
not apply to motors which are already utilized according to thermal class F in their standard design.
Connection diagrams
Star connection
Star connection is obtained by connecting terminals W2, U2, V2 to each
other and terminals U1, V1, W1 to the mains.
Phase current and phase voltage are: Iph = IN; Vph = VN / 3
where IN is the rated current and VN the rated voltage at star
connection.
Delta connection
Delta connection is obtained by connecting the end of a phase to the
beginning of the next phase.
Phase current and phase voltage are: Iph = IN / 3; Vph = VN
where IN and VN are rated current and rated voltage at delta
connection.
Star-delta connexion
Star-delta connection permits a reduction of the starting current, ensuring however that the resulting starting
torque obtained is higher than the load torque. Thereby it should be observed that the torque of an asynchronous
motor is directly proportional to the square of the voltage. Motors whose rated voltage with delta connection
corresponds to the mains voltage, can be started with the star-delta method.
All motors can be supplied with windings designed for star-delta starting (for example: 400 V Δ / 690 V Y).
Starting rate
The number of starts per hour given in the table below is permitted
without specific check, provided that the following conditions are
met::
§ Additional moment of inertia ≤ moment of inertia of the rotor
§ Load torque increases to nominal torque quadratic to the speed
§ Starting in evenly intervals
Permissible starts per
hour at number of poles

Please consult us and specify the complete operating conditions in order to ask for the permissible number of
starts for motors of frame size 355.
General specification 11
1.14 Motor protection
The selection of the thermal motor protection should result from the existing operating conditions. Motors may
be protected by means of current-dependent motor circuit breakers or overcurrent relays and temperature
sensors.
Motor protection is possible as follows:
§ Motor circuit breaker with overcurrent-time-trip
§ Thermistor protection with thermistor temperature sensors (PTC) in the stator winding combined with relay
(if required, with additional motor circuit breaker).
§ Resistance thermometer for monitoring of winding and bearing temperature (PT100).
§ Bimetal temperature sensor as N.C. or N.O. in the stator winding (if required, with additional motor circuit
breaker).
Although there are motors available from stock with built-in thermistor temperature sensor, a special remark has
to be made in the enquiry or order when motor protection is required.

1.15 Three-phase squirrel-cage motors driven by frequency inverters
The motors in standard design are suitable for operation on static frequency inverters, taking into account the
following remarks:
§ Maximum inverter output voltage 500 V at peak voltages Û ≤ 1460 V and dv/dt ≤ 13 kV/ms. For higher inverter
output voltages or higher stress a special insulation is required.
§ At square characteristic of the load torque, motors can be operated with their rated torque (exceptions are
marked in the selection tables).
§ In case of constant torque, the rated torque must be reduced for self-ventilated motors due to reduced supply
of cooling air. Depending on the speed range, the use of an external fan is recommendable.
§ Standard motors designed for 230V Δ / 400V Y, 50 Hz can be operated with delta connection at 400 V and a
base frequency of 87 Hz (observe the mechanical speed limits).
§ For motors from frame size 280 we recommend an insulated bearing at the non-drive end.

Voltage capability
The insulating system of the motors is suitable for inverter output voltages ≤ 500 V. Higher voltages are available
on request.
Noises
Depending on the operating point, the type of inverter and the set pulse frequency, inverter-fed motors produce
between 1 and 15 dB(A) higher noise values than at mains operation.
Motors that are operated with a frequency over 50 Hz have more air noise. In this case we recommend the use of
an external fan.
Vibration severity
When operating at high speeds (according to frequency > 60 Hz) a reduced vibration severity “B” according to
EN / IEC 60034 part 14 may be required, measured at a mains frequency of 50 Hz or 60 Hz and sinusoidal mains
voltage.
