Alternating power supply circuit of and alternating power supply method for long stator linear motor

Abstract

An alternating power supply circuit of and an alternating power supply method for a long stator linear motor, and a long stator linear motor, relating to the technical field of motors. The alternating power supply circuit of the long stator linear motor comprises three-phase stator winding branch circuits, the stator winding branch circuits of respective phases being connected to a converter, the stator winding branch circuit of each phase comprising N sections of stator windings connected in series, each section of the stator windings being connected to a switching circuit in parallel, and when the switching circuit is closed, the parallelly-connected stator winding being short-circuited. Using the alternating power supply circuit of the long stator linear motor can increase the speed of switching power supply for stators, thus reducing the usage of power supply devices and system complexity.
