CHINA FACTORY HIGH VOLTAGE PHASE ROTOR(Slip Ring) ELECTRIC MOTORS WITH AIR-WATER COOLING SERIES YRKS, 6 kV, 10 kV. CHINA FACTORY HIGH VOLTAGE ELECTRIC MOTORS YRKS

YRKS-series (3kv, 6kv, 10kV) motor, is of wound rotor three phase asynchronous motor. Which complies with JB/T7594-1994 and JB/T10314.1-2002. The protection degree of the motor is of IP23 and the cooling method is of ICW81A.

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.

The structure and the mounting type is of IMB3 with continuous duty(S1).The rated frequency is 50Hz and the rated voltage is 3000V, 6000V,1000V, other voltage requirement or special requirements should be negotiate with manufacturer before order is placed.

When ordering, the following requirement should be specified:

Frame size such as: YRKS5001-4

Mounting type: IM B3

Rated Power: 900KW

Protection Degree: IP44/IP54
