Information on engineering motors for variable-speed drives
What has to be observed when engineering drive converter motors?
 Utilized according to temperature rise Class F or de-rating for temperature rise Class B.
 A wide speed control range is utilized (up to 0 Hz)
 Self-ventilated motors are de-rated by up to 50%
 Or a separately-driven fan is used: 1PQ, option G17
 A rotary pulse encoder is used for high speed accuracy
 Ratio of the power ratings, motor/drive converter
 Min 1/4 for Vector or 1/8 for V/f; max 3/2
 Capacitive re-charging currents demand:
 Good grounding and if possible, shielded motor cables
 Motor windings with the appropriate voltage strength (standard for Siemens motors up to
500V) or the use of motor filters (dV/dt or SINUSOIDAL)
 For 690V motors with increased voltage strength: ..PM.
 Insulated bearings from SH 280 option L27 or standard for 1LA8
 Note the maximum cable length to the motor
 In hazardous zones:
 Explosion-protected motors for class of protection, flameproof enclosure EEx de IIC.
 Utilized according to temperature Class B
 Motors must be equipped with PTC thermistors.
 Drive converter with evaluation devices in accordance with PTB (L83, L84)
 Terminal boxes are as standard in Class of protection, increased safety EEx e II.
 In addition to the EC type-test examination, a general certificate of conformance is
 required for drive converter operation. (ATEX)

 For drive converter operation, the
standard 1LA and 1LG motors can
provide the full rated power. They
are then utilized according to
temperature rise Class F.
 If the motors are only to be used
according to temperature rise
Class B, then they must be de-
rated by 10 %

Increased voltage stressing
Line supply voltage >500V
 Either select a motor with increased insulation strength: M
Example: 1LA8315-2PM
Note the lower power de-rating!
Output filters limit
the voltage rate-of-rise dv/dt to values < 500V/µs and typical voltage spikes to <1000V
for Vline supply < 575V and <1150V for Vline supply < 690V.
Line supply voltage < 500V
Siemens standard motors have the leading
edge Durignit ® IR 2000 insulating system
(IR = Inverter Resistant).
They are inverter proof up to 500V.

Bearing currents and motor size
Bearing currents
 AC drive converters with PWM generate re-charging currents. Especially for large
motors, under worst-case conditions - e.g. longer periods of operation at low
frequencies – the bearings could be damaged.
 The first measure is to use shielded motor cables and use good grounding.
 An additional measure is to use insulated bearings at the non-drive end:
1LA8 for drive converter operation: Standard
1LG4/6 from frame size 280: Can be ordered using option L278
Motor – drive converter combination
 Rated motor current as a ratio to the rated drive converter current:
 For closed-loop Vector control minimum 1/4
 For V/f open-loop control minimum 1/8
 Rated motor current at the maximum, the same as the maximum overload current
of the drive converter: Otherwise possible trip or power reduction if there are
significant current spikes on low-inductance motors
