PERMANENT MAGNET SYNCHRONOUS ELECTRIC MACHINE

摘要

Disclosed is a permanent magnet synchronous motor, comprising a stator (1) and a rotor (2). A plurality of wire slots (3) are circumferentially distributed on the stator (1), and each wire slot (3) is provided therein with a coil (4). A stator tooth (5) is provided between every two adjacent wire slots (3). A plurality of sets of magnet slots (6) are circumferentially distributed in the rotor (2), and each set of magnet slots (6) comprises at least two magnetic steel slots (7). A permanent magnet (8) is provided in each magnetic steel slot (7). A magnetic channel (9) is formed between every two adjacent magnetic steel slots (7), and of every two adjacent magnetic channels (9), ends of one magnetic channel (9) correspond to the wire slots (3), and ends of the other magnetic channel (9) correspond to the stator teeth (5). Thereby the output torque of the permanent magnet synchronous motor is more stable, and the noise and vibration in operation are reduced.
