Brief Introduction

SIMO YRKK500-6G is a heavy-duty 10kV high voltage wound rotor three-phase asynchronous motor, professionally manufactured by Xi'an SIMO Motor Co., Ltd. As a classic model of YRKK series slip ring induction motors, this 630kW industrial electric motor adopts thermal class F motor insulation design, engineered for harsh industrial scenarios requiring high starting torque, limited starting current and frequent startup operations. It complies with IEC international standards, obtains CE certification, and has become a reliable driving solution for global mining, cement, metallurgy, chemical and bulk material handling industries.

This YRKK500-6G motor runs at 50Hz, rated speed 992 r/min, rated power 630kW with an outstanding efficiency of 93.3% and power factor 0.84. The stator operates at 10000V, rated stator current 46.4A, while rotor voltage reaches 943V with rotor current 414A. Both stator and rotor adopt Y connection. As a standard thermal class F motor, its maximum allowable temperature reaches 155℃, greatly extending service life under continuous S1 duty cycle. The motor adopts IC611 air-to-air cooling method and IP54 protection grade, effectively blocking dust, moisture and debris, ideal for outdoor and dusty workshops. The mounting form IM B3 (horizontal foot-mounted) supports flexible installation matched with reducers, crushers and conveyor equipment.

One core advantage of the SIMO wound rotor induction motor lies in its unique slip ring structure. By connecting external variable resistance to the rotor circuit, users can achieve high starting torque under low starting current. This perfectly solves the difficulty of direct startup for heavy-load machines when grid power capacity is insufficient, which cannot be realized by ordinary squirrel cage high voltage motors. It is worth noting that the rotor winding is forbidden to be short-circuited directly during startup as marked on the motor caution plate. For long-term stable operation, external circulating lubrication and cooling conditions must strictly follow the technical data on the nameplate.

Reliable bearing configuration guarantees stable long-term operation. The drive end uses NU232ECM bearing, and non-drive end adopts 6228/C3 bearing. The whole machine weighs 5860kg, robust cast iron structure suppresses vibration and running noise. The motor is designed to adapt to extreme working conditions, allowing maximum ambient temperature up to 40℃ and applicable altitude up to 3700 meters, satisfying projects built in plateau areas. Strict quality control is implemented throughout all production procedures; each unit undergoes complete factory testing before delivery.

SIMO YRKK series high voltage slip ring motors are widely applied to drive ball mills, ore crushers, long-distance belt conveyors, industrial fans, heavy-duty pumps and winches. Compared with competing products, SIMO motors balance high efficiency, low maintenance cost and strong overload capacity. The durable structure paired with the stable performance of a thermal class F motor ensures stable operation under continuous heavy loads. Supported by the global after-sales network of Xi'an SIMO Motor, customers can access timely technical guidance, spare parts supply and on-site service worldwide.

If you are searching for a durable 630kW 10kV wound rotor asynchronous motor for heavy-load industrial equipment, SIMO YRKK500-6G is your cost-effective choice. We support customized parameters on voltage, cooling, sensors and special coating to match personalized project requirements.
