Description

technical field [0001] The invention discloses a method for preparing an AC servo motor, in particular relates to a method for preparing an AC servo motor with high speed and high power density, and belongs to the technical field of motors. Background technique [0002] As the mainstream actuator of incremental motion control, the research and application of stepping motor system has made great progress. The development of stepping motor drive control technology has improved or overcome the problems of stepping motor system such as out of step, oscillation, excessive driving current (low efficiency), etc., but the inherent low power density of stepping motor The problem persists. In addition, the development of drive circuit and control technology makes it possible to simulate the operation characteristics of traditional multi-pole logarithmic stepping motors by using few-pole logarithmic motors. For example, the AC servo motor (three-phase permanent magnet synchronous mot...
