Siemens: SIMOGEAR Reluctance Geared Motor

May 27, 2019

The new SIMOGEAR synchronous-reluctance drive system consists of SIMOGEAR standard gear units, SIMOTICS synchronous-reluctance motors and SINAMICS frequency converters. With this solution, Siemens is widening the SIMOGEAR geared motors portfolio by newly combining the gearbox with the reluctance motor from SIMOTICS as a completely new offering for the customer.

By combining the aforementioned products the customer benefits especially from the efficiency class compared to IE4, which scores with higher efficiency and lower losses, especially in a partial load than to comparable asynchronous motors. Highly energy efficient, the motor heats up less and provides a high operation reability due to its excellent thermal behavior. Because of that high service factors are achieved.

This solution also boasts with high dynamics thanks to the motor’s lower moment of inertia and optimized control. Commissioning is established quickly and easily by entering the motor code into the converter. The constant torque-speed characteristics up to the rated speed make an external fan redundant. In the drive system, all components are perfectly coordinated together.

Compact

  • Siemens is expanding the SIMOGEAR portfolio which meets customer requirements as well as market standards regarding mounting dimensions.
  • Shorter and compact design together with fine torque graduation is a standard for the SIMOGEAR gearboxes.
  • Coupled with SIMOTICS reluctance motors and SINAMICS frequency converters, the new drive systems with an excellent operation appear.

Rugged

  • Overload capacity of up to 200%.
  • Without permanent magnets the synchronous-reluctance motor is easier to service than synchronous motors with permanent magnets.
  • The SIMOGEAR reluctance geared motor add to the robustness of the whole system in different environmental conditions.

Energy efficient

  • Optimum functionality of the drive system is provided by the interaction of the reluctance motor, gear unit, and converter which are precisely matched to each other.
  • The system boasts with high dynamic performance through optimized control and low moment of inertia.
  • SIMOGEAR reluctance geared motors exceed energy efficiency IE4.
