Lower Operating Costs - Higher Availability

High-Torque Motors SIMOTICS HT Serie HT-direct

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.

SIMOTICS HT benefits & applications

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

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

  • Branch Chemical Industry, Oil & Gas
  • Branche Water / Waste water
