YBBP series low voltage flame proof frequency control three phase asynchronous motors (hereinafter referred to as "the motors") are a series of new products developed by our company to meet the market demand. In conjunction with a frequency inverter, the motor can realize smooth step less speed variation over a wide range. 

The motors flame proof marks include EXDI, EXDIIBT4, EXDIICT4.  The motors have two cooling methods: IC411(fan-ventilated series) and IC416(forced ventilation series).  The frame size range of the fan-ventilated series(IC411) is H280 and below. The fame size range of the forced ventilation series (IC416) is H160 and above.
