Description

technical field [0001] The invention belongs to the field of motor control, and in particular relates to a six-phase linear induction motor energy chain switching system and its control system and method. Background technique [0002] Linear motors are evolved from ordinary rotary motors, and are electric transmission devices that can directly convert electrical energy to mechanical energy for linear motion. Due to the integration of devices such as chains, ball screws, and gears, traditional rotating electrical drive systems have disadvantages such as large volume, low efficiency, low precision, and low power density. Using its own structural advantages and combining advanced control technology, linear motors can not only overcome the above shortcomings, but also break through the bottleneck problem of limited acceleration and speed through thrust control, and at the same time have good dynamic performance. [0003] Wheatstone in the United Kingdom first proposed the desig...
