Description

technical field [0001] The invention belongs to the field of electric conversion, and in particular relates to a variable frequency motor. Background technique [0002] A motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electropermanent magnet block winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, a current passes through the effective side of the stator winding and is subjected to the action of the magnetic field to make it rotate. According to the principle of motor reversibility, if there is no change in the structure of the motor, the motor can be used as a motor or as a generator. Usually, the active part of the motor makes a rotary motion, which is called a rotor motor; there are also linear motions, called a linear motor. Electric motors can provide a wide range of power, from mi...
