The Siemens Drive Technologies Division has combined all its electric motors into one product family with the name Simotics, to improve clarity of choice for customers when selecting a motor for an application. The motors cover almost all application areas, and are an essential component of the division’s integrated drive train. The range includees low voltage induction motors, motors for motion control applications as well as DC and high voltage motors.
The low voltage motors for general industrial applications include the Simotics GP general purpose energy-efficient induction motors. Siemens offers these motors with aluminium frame in shaft heights 80 to 160 and power ratings of 90 W to 45 kW. Typical applications include pumps, fans and compressors with special requirements regarding low weight and high efficiency.
Siemens offers a comprehensive range of compact motors for motion control applications for exact and dynamic positioning and precise motion control of drive shafts. The new Simotics motor class includes the Simotics S Synchronous servomotors with power ratings from 50 W to 34 kW, characterised by high dynamic response and precision. The motors cover a torque range from 0,08 to 125 Nm and have been designed for tasks including positioning and continuous-path control in high-performance production machinery, as well as for use in general mechanical equipment manufacture.
The Simotics portfolio also includes the Simotics DC motors with power ratings up to 1610 kW, used for example in extruders for the plastics industry, as drives for hoisting and traversing gear in cranes and as rolling mill drives. In addition, the product family also includes high voltage motors with power ratings to over 100 MW and speeds of 10 to 15 000 rpm. The motors are available in different construction types and degrees of protection. As main drives, they are often the heart of a plant and are characterised by high reliability in applications such as compressors and pumps in the oil and gas industries, or mills in mining applications.
