Series 5

Reliable and compact high voltage asynchronous slip ring motors

simotics hv series 5

As a result of their modular design, the 1R.5 slip ring rotor motors (US: wound-rotor motors) can be produced with various cooling systems. This means that the motors can be flexibly adapted to the customers's application. The enclosed slip ring compartment – located inside the NDE bearings – provides a high degree of protection for the complete motor, i. e. for the motor and slip ring compartment.
