YRKK-series 6KV, 10KV wound rotor three phase asynchronous motor
1.Brief Description:
YRKK-series 6KV, 10KV wound rotor three phase asynchronous motor conform to IEC standard. The motor has such advantages as high efficiency, energy-saving, low noise, low vibration, light weight and reliable performance. They are easy for installation and maintenance. The motor can generate larger starting torque at the state of relatively lower starting current and the speed can be adjusted within a limited range. It is suitable for the following applications:
A larger starting torque is required that cannot be obtained from a squirrel-cage motor.
The capacity of the feeder line is insufficient to start a squirrel-cage motor.
Applications where the longer starting time and frequent starting are needed.
Adjustment of speed is needed with in a limited range such as windlass, press machines, drawing machines, etc.
The YRKK-series motor adopts Class-F insulation. The bearing structure is designed according to IP54,and grease lubrication are used Non-stopping ill-filled and oil-discharging units are provided.
The structure and the mounting type of the motor is of IMB3 with continuous duty(S1),The rated volt are 6kv,10kv,other voltage requirement or special requirement should be negotiate with manufacturer before order is placed.
2.The meaning of Type:
