某公司机电修配厂B2016A型龙门刨床改造前应用的调速系统为K-F-D(发电机组电动机)调速系统,交流电机拖动直流发电机再拖动直流电动机,由交磁放大机控制发电机的励磁系统,结合机械传动,达到20∶1的机电联合调速系统。进刀机构采用进刀继电器控制进刀,由于继电器控制时有粘连发生
The speed governing system applied before the transformation of B2016A gantry planer of a company’s mechanical and electrical equipment repair factory is KFD (generator set motor) speed control system. The AC motor drives the DC generator and then the DC motor, and the alternator controls the excitation of the generator System, combined with mechanical transmission, to achieve 20: 1 electromechanical joint speed control system. Feed mechanism using feed-in relay control feed, due to sticky when the relay control occurs
