YRKK-series ( 3kv, 6kv, 10kV) motor, is of wound rotor three phase asynchronous motor. Which complies with JB/T10314.2-2002. The protection degree of the motor is of IP44/IP54 and the cooling method is of IC611.

        The motor has such advantage as high efficiency, energy-saving low noise, low vibration, light weight and reliable performance. They are easy for installation and maintenance.

        This motor can generate larger starting torque at the state of relatively lower starting current. It used where the capacity of the feeder line is insufficient to start a squirrel cage motor or where the longer starting time and frequent starting are needed or where adjustment of speed is needed within a limited range such as windlass, press machines, drawing machines.
