Products Description
Brief Description
YR Series High-Voltage Slip Ring Motor (Made in China) is of wound rotor three phases asynchronous motor (center height from 710mm to 1000mm), which complies with JB/T13957-2008. The protection degree of the YR motor is of IP23 and the cooling method is of IC01.
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.
Application
YR Series High-Voltage Slip Ring Motor (Made in China) 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 6000V,other voltage requirements or special requirements should be negotiate with the manufacturer before order is placed.
