Test field drives | Slip ring (IC 81W)

Three-phase slip ring motor for a compressor test facility in Germany

Customer: Man Turbo AG (Germany)

Menzel was asked to supply a motor for a compressor test field. The motor was supposed to be used variably also at different rotational speeds. Therefore, a force-cooled option was developed which can be employed independently of speed, with a separate cooling circuit for the for slip rings. Menzel realized a slip ring motor in order to achieve a low starting current and a maximum starting torque without converter application.
