The variable-speed-drive motors are based on the platform of the Innomotics GP General Purpose Motors. The design corresponds to the line motors – the mechanical parts are identical. However, instead of the squirrel cage induction rotor, they utilize one of the two available synchronous technologies. Together with an appropriate frequency converter they provide an outstanding performance and reach an extremely high energy efficiency (IE4 or IE5), also at partial loads. In addition, a large number of the variations available for the line motors (types of construction, motor protection, terminal box position, and options) are also available for the VSD motors.

• Synchronous reluctance motor
  For particularly energy-efficient operation, with keeping the standard power-shaft height assignment, the best choice is a VSD system with an Innomotics reluctance motor. The reluctance technology, without any rotor winding, ensures particularly high dynamic performance and high efficiencies even in the partial load range, as well as high process quality.

• Permanent magnet motor
  This advanced technology with permanent magnets in the rotor enables not only an outstanding IE5 energy efficiency, but also a high power density. The permanent magnet motor can be even three frame sizes smaller than an induction motor of the same power rating. Furthermore these motors provide a constant torque from the lowest speed and cover high overloads and overspeeds.
