焦煤集团冯营公司煤矿为1958年建井的老矿,主井采用原苏联的2БM3000/1 500型绞车,电机仍为传统的三相绕线型异步电动机,其调速方法是在电动机转子回路中串入电阻,用主令控制器逐段切除电阻来达到调速的目的。这种系统的制动方式为能耗制动,制动所产生的能量全部消耗在电阻上。电动机转子串电阻调速系统的调速,属有级调速,开环控 The coal mine of Coking Coal Group Fengying Company was an old mine built in 1958. The main shaft adopts the 2БM3000 / 1 500 winch of the former Soviet Union. The motor is still a traditional three-phase wound type asynchronous motor. The speed regulation method is in the motor rotor circuit In the string into the resistance, with the master controller to remove the resistance section by section to achieve the purpose of speed. Braking this system for energy braking, braking all the energy consumed by the resistance. Rotor speed resistor motor speed control system, is a speed, open-loop control
