Description

technical field [0001] The invention relates to an AC asynchronous motor, in particular to an AC asynchronous motor adapting to a dual-voltage system with an adjustable number of parallel branches. Background technique [0002] AC asynchronous motors are widely used in various fields because of their simple structure, reliable operation, and convenient maintenance. Under the current technical conditions, AC asynchronous motors are generally difficult to meet the needs of changing voltage systems due to their own structural limitations. Specifically, in the existing AC asynchronous motor, the number of parallel branches of the stator winding is fixed (that is, cannot be adjusted), so it can only meet the working conditions of one voltage system power supply. If the voltage system needs to be changed, AC asynchronous motors with different parameters need to be remanufactured to meet the needs of changing the voltage system, which brings about the problems of heavy manufacturi...
