Embodiment Construction
[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] figure 1 A high-power, high-reliability permanent-magnet fault-tolerant hub motor for an electric armored vehicle of the present invention consists of a stator assembly 1 (stator core 15 and stator winding 16), a rotor assembly 2 (a permanent magnet of unequal thickness 12, a rotor core 13, Rotor baffle plate 7 and carbon fiber protection sleeve 14), bearing 3, rotating shaft 4, front end cover 8, rear end cover 5, casing 6, O type sealing ring 11, lip type sealing ring 20 and position sensor 9 constitute.
[0028] Wherein, the stator assembly is composed of a stator core 15 and a stator winding 16 . The stator core 15 is made of high magnetic saturation and low loss electrical silicon steel; the stator winding 16 is made of high temperature resistant single crystal copper wire or silver wire to improve the conductivity of the windin...
