introduction：Permanent magnet synchronous motorHave simple structure，Small size、High efficiency、High power factor advantage。At present，Permanent magnet synchronous motors are already in the metallurgical industry（Ironworks and sintering plants, etc）、Ceramic industry（Ball mill）、Rubber industry（Internal mixer）、Oil industry（Pumping unit）、Textile industry（Double twister、Spinning frame）And other industries、Low voltage motor in the performance，And gradually accumulate design and operation experience。 So heres the question，Is the permanent magnet synchronous motor a DC motor？But for，So what category does it fall into？ 1、Permanent magnet synchronous motor is not DC motor； 2、“Permanent magnet synchronous linear motor”Its AC motor.，Because whether it is used as a generator or an electric motor，The current in its stator windings is AC，And its moving son（oscillator）There are permanent magnets on it，The required winding also has no current。 （1）“Permanent magnet”Refers to the rotor of the motor（Counter rotating machine）Or actor（Linear
