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 / Innomotics 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.
• 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.
• 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)
