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.

Benefit
- 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.
