◆概述
随着电力、电子技术的惊人发展，各行各业的机械、电器设备越来越多的采用电动机变频调速与控制技
术，在调速领域，引导了一场取代传统调速方式的更新换代。由于变频电机可直接应用在需要特殊速度调整的
场合，其特点有宽范围、恒转矩调速特性，调速平稳，无转矩脉冲，与各类变频器有良好的参数匹配，可实现低频大力矩，高精度转速控制、位置控制及快速动态响应。YVF系列变频电动机，广泛的应用于冶金、石油、轻工、医药、纺织、印染、数控机床、泵类、风机等行业。
◆Brief introduction Along with the astonishing development of the electronics technology, frequency conversion, speed-adjusting and control technology iswidely applied to the fields of the machinery and the electric appliance equipment from all the various trades. The updating of the traditional speed-adjustiong modes has already been made in the fields of the speed-adjusting.frequency conversion motors can bedirectly used in the situations when the special speed requires to be adjusted.With its characteristics of the wide range of speed-adjusting, the constant torque speed-adjusting,smoothly running and no torque pulse,the frequency conversion motor can match with various converters.It is low frequency and large torque, high accuracy speed control and position control,and quick dynamic response..YVF series frequency conversion motor is widely applied in such areas as metallurgy, petroleum,light industry,medicine,textile, printing and dyeing, numerical control machine, pump and fan,etc
