| description | The invention provides a tangential-type permanent magnet synchronous motor rotor, which comprises a rotor core, a shaft, first air grooves, second air grooves, permanent magnet grooves, permanent magnets, a stator core and third air grooves. The rotor core is fixedly arranged on the outer wall of the shaft; and the first air grooves and the second air grooves are arranged alternately at the external near-shaft end of the shaft. The groove walls of the second air grooves or the third air grooves have zigzag bulges, thereby facilitating epoxy resin to be attached to the groove walls of the second air grooves or the third air grooves of the rotor, and improving heat radiation capability; the second air grooves or the third air grooves are filled with epoxy resin, thereby helping to strengthen the mechanical strength of the rotor and enhancing the rotor heat radiation effect; and through arrangement of the first air grooves and the second air grooves, leakage flux of magnetic poles of the permanent magnets can b |
