SIEMENS MOTOR
Low-voltage induction (squirrel-cage) electric motors
Represent the fundamental part of firm
assortment. Motors with single or three phase supply in the range of 220V – 690V, covering the power spectrum of 0,06kW – 1250kW, are considered to be low-voltage motors.
Standard energy-saving motors (increased efficiency)
Siemens the mostly used electric motors for all kinds of prevailing applications, running in common working environment (with exception of explosion or inflammation
hazard).
This category covers mainly series 1LA7, 1LG4, 1LE1 and derived, with power scale from 0,04 to 200kW. Both bipolar and four-polar motors are certified as EFF2 (higher efficiency) according to CEMEP, newly marked as IE1.
The key advantages are as follows:

The key advantages are as follows:
- Operation energy savings
- The broadest configuration possibilities – installation of modular bodies (electromagnetic brakes, ventilation units, IR, heat protection etc), various mechanical modifications (alteration of shaft shape, various positions of junction boxes, various bearings types, etc.)
- Standardized dimensions ensuring compatibility with other brand products
- Very high availability
High efficiency motors
Siemens electric motors used for common applications, with high operation energy savings. Motors designed for these customers who are aware of the fact that primary drive costs are usually not relevant sums comparing the total drive cost.
This category covers mainly 1LA9, 1LG6, 1LE1 and derived, with power scale from 0,06 to 200kW. Both bipolar and four-polar motors are certified as EFF2 (higher efficiency) according to CEMEP, newly marked as IE1.
Explosion proof motors:
Siemens electric motors for running in environment with higher danger of inflammation caused by flammable vapours, gases and combustible dust.
Power scale from 0,06 to 132kW, 900kW on demand
This category covers following series:
