AC permanent magnet motor

An alternating current (AC) permanent magnet motor, wherein the AC permanent magnet motor comprises a stator and a rotor, a power source suppled to the AC permanent magnet motor is input by an external controller;

• each of silicon steel cores of the stator is provided with some cable troughs and some coil windings, the stator core is provided with grooves, stator permanent magnets are mounted in the grooves, silicon steel sheet grooves comprise enclosed grooves and open grooves, and the two types of grooves are laminated with each other to form a stator core in a fence shape;
• a coil unit of the stator comprises at least two of the adjacent same stator cores, the stator permanent magnets in the grooves, and four same coils inserted into the cable troughs, and some same coil units form a three-phase stator coil;
• the rotor comprises a rotor core, a closed squirrel cage on the core, and a rotor permanent magnet in a core groove;
• and the controller outputs the power source on which three-phase fully-controlled rectification is performed and that has same positive and negative half sine-waves or step-wave pulses, to connect to 7 lead line ends of the three-phase stator coil by using a dedicated plug and socket;
• wherein connectors of some lead lines of windings of stator coils in the AC permanent magnet motor are connected to a dedicated plug having a total of seven pins comprising six live line pins and one zero line pin in advance according to design requirements, when the AC permanent magnet motor is used, the dedicated plug is inserted into a dedicated socket associated with the dedicated plug, the number and sectional shapes and dimensions of the metal pins of the dedicated plug are the same as those of jacks of the dedicated socket, and DC power output lines of the controller are connected to the dedicated socket having a total of seven jacks comprising six live line jacks and one zero line jack.
