我国自主研制生产的新型电牵引采煤机MG132/320WD是由牵引机构、截割机构、调高系统、辅助装置和电气系统等构成。它既保留了老型号采煤机的一些结构特点,又采用了新型的SRD开关磁阻调速系统。SRD开关磁阻调速系统,是具有典型机电一体化结构的无级调速系统。该系统在技术及结构
China’s independent development and production of a new type of electric traction shearer MG132 / 320WD by the traction mechanism, cutting mechanism, adjusting system, auxiliary devices and electrical systems. It not only retains some of the structural features of the old shearer, but also uses a new SRD switched reluctance speed control system. SRD switch reluctance speed control system, is a typical mechatronic structure of the stepless speed control system. The system is in technology and structure
