该系列产品调速范围，在5-50Hz恒转矩运行，50-100Hz恒功率运行，运行平稳、转矩脉动小。根据使用要求，分带编码器的和不带编码器的两种。安装独立风扇冷却装置，使电机在不同转速下均有良好的冷却效果。电机带编码器时起动更平稳、控制更精确。

该系列产品适用于风机、水泵、液压站、塑料机械、造纸机械、橡胶机械等需要无级调速的场合，可替代YCT系列电动机，效率和控制精度高。

YVP series motors are AC variable frequency step less speed regulation motors which are specially designed and mating with asynchronous frequency inverter. The motors can run under variable frequency power source and have two types: with encoder and without encoder. Speed range, constant torque running in 5-50Hz and constant power running in 50-100Hz, stably and with small torque pulsation. According to usage requirement, it has two types: with encoder and without encoder. It can be equipped with independent fan cooling device to ensure better cooling effects under different speed. With encoder, the motor starts smoother and the control is more precious. This series motors apply to fan blower, water pump, hydraulic pressure station, plastic machinery, paper machinery, rubber machinery which need step less speed regulation, The motors with higher efficiency and accuracy can replace YCT electric motors.
