The SIMOTICS HT Series HT-direct 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 SIMOTICS HT Series HT-direct high-torque 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.

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
Applications where the following are important - high efficiency, low space requirements with low lifecycle costs for the drive solution. The main application of the SIMOTICS HT Series HT-direct high-torque motors areas are as follows:
Paper industry as roller and press drive
Marine industry as propeller drive (main and auxiliary drives)
Mining industry for mill drives
Steel industry e.g. for shears
Plastics industry as drive for extruder worms, foil-drawing machines
Crane industry for the widest range of applications
Sugar industry for sugar centrifuges
