[0030] Example
[0031] Such as figure 1 As shown, the present invention is based on a high-reliability electric drive system of a permanent magnet fault-tolerant motor, including a high-reliability permanent magnet fault-tolerant motor, two sets of three-phase full-bridge drive circuits, two bidirectional thyristors, six fuses and an independent 270V DC power supply.
[0032] Further, the permanent magnet fault-tolerant motor is composed of a twelve-slot stator and a five-pair pole surface-mounted permanent magnet rotor. The twelve-slot stator includes two sets of mutually independent and symmetrical three-phase single-layer concentrated tooth-isolated windings. The armature windings are ABC windings and XYZ windings; the rotor adopts the rotor magnet centrifugal structure.
[0033] Further, the two sets of three-phase full-bridge drive circuits are respectively composed of six power switch tubes, and the three-phase full-bridge circuit drive control is composed of six power switc...
