Customer benefits

• 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
