High-Torque Motors SIMOTICS HT Series HT-Direct

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 motors are offered as a harmonized system together with SINAMICS drive converters.

The HT-direct motor / SINAMICS drive converter represents a drive solution with a long service lifetime but with low lifecycle costs and high efficiency for applications with low operating speeds.
Features
  • With slow-running drives, the efficiency of the HT-direct series 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 HT-direct series 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 HT-direct motor for operation with or without encoders
  • Thanks to their long service life (nominal bearing lifetime > 60000 hours), HT-direct 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
