该系统具有变频、工频两种运行方式，若变频工作状态下出现故障，系统能自动转换到工频状态下工作，避免因变频系统故障而影响电机的运行，具有过转矩、过压、过电流、缺相等保护功能。

     his system is an integrated device which is composed of YVP series variable frequency motor and intelligent variable frequency system. It is a high efficiency and energy-saving product developed by our company for coal-bed gas. It has two kinds: with encode and without encoder.  This system has two running modes: frequency conversion and power frequency. If it breaks down under frequency conversion, the system can automatically exchange to work under power frequency to avoid effecting motor running because of frequency conversion system fault.  It has features of over-torque, over voltage, over current and phase lose.

   性能特点 Performance features：

   1. YVP系列变频调速电动机与调速装置配套使用，构成交流变频无极调速系统，采用矢量控制。在1~50Hz频率范围内作恒转矩变频调速运行，在50~100Hz频率范围内作恒功率变频调速运行，运行平稳，无转矩脉动现象，具有起动转矩大、起动电流小等优点。

   2、当YVP系列变频调速电动机安装编码器时与控制系统构成闭环控制，可以很好的满足转速、位置、转矩等控制要求，控制精度高，始终保证整个系统高效节能，同时可替代一般的伺服控制。

  I.Mating with speed regulation device, YVP series variable frequency adjustable speed motor constitutes an AC frequency converting step less speed regulation system which is vector controlled. It operates with constant torque frequency converting speed changing in frequency range 1~50Hz and operates with constant power frequency converting speed changing in frequency range 50~100Hz. It runs stably, no torque pulsation phenomenon and has advantages of large starting torque, small starting current.

   Ⅱ.When the YVP series variable frequency adjustable speed motor is assembled with  encoder, YVP series variable frequency motor constitutes a loop control to well meet controlling requirement of speed, location, torque. It controls with high accuracy and always guarantees the whole system to be high efficiency and energy saving. At the same time, it can replace general servo control.
