Innomotics DP Definite Purpose Motors – High Torque Motors

Innomotics DP Definite Purpose Motors – High Torque Motors

The high torque motors are permanent-magnet synchronous motors that can provide high torques at low speeds directly at the driven machine. High efficiencies and good power factors can also be achieved at low speeds as a result of the permanent magnet rotors. 

The high torque motor in combination with a converter represents a drive solution with a long service lifetime but with low lifecycle costs and high efficiency for applications with low operating speeds.

Technical data overview

Recommended converters: SINAMICS* G and S converter series.

Benefits & applications

• With slow-running drives, the efficiency of the Innomotics High Torque Motors is approximately 2 to 3% higher than for similar drive concepts, if gear or gear steps can be saved. For a 1000 kW motor, this results in a saving of 33 kW, which is an annual saving of approximately, 15000€ for an operating time of 8 hours per day.
• High pole design in combination with permanent magnet technology ensures that the space requirement and mass of the motors are lower than for similar asynchronous machines. The slow-running motors of the Innomotics High Torque Motors obviate the need for a gearbox in many cases (reduction in engineering, assembly and maintenance outlay, lower investment and lower operating costs).
• Efficient, optimally matched drive system, SINAMICS* converter and Innomotics High Torque Motors for operation with or without encoders
• Thanks to their long service life (nominal bearing lifetime > 60000 hours), Innomotics High Torque Motors are maintenance-free and have a high availability especially for applications in which a gearbox can be omitted
• Environmentally friendly system (where applicable, no disposal of gearbox oil is necessary; energy-saving drive system).
• Customization is possible.
