Slip-ring three-phase asynchronous electric motor Siemens Large Drives

As a result of their modular design, the 1R.5 slipring 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 slipring compartment – located inside the NDE bearings – guarantees a high degree of protection for the complete motor, i.e. for the motor and slipring compartment.
