Two phase linear motor under control
Two phase linear induction motors (LIM), belong to the group of special electrical machines. They convert electrical energy directly into mechanical energy with linear motion. There are various applications for LIM; e.g. trains, sporting equipment, elevators, CDROMs, , robots..etc. The speed control methods are applied here to the LIM , are :amplitude, time phase ,frequency ,voltage and voltage frequency control. ... إقراء المزيد
