Annular channel structure between stator and rotor of shielded motor
An annular flow channel, shielded motor technology, applied in the direction of magnetic circuit shape/style/structure, electric components, electromechanical devices, etc., can solve the difficulty of further improving the speed and power density of shielded motors, increase cooling measures and structural weight, and reduce shielding. The reliability of motor operation and other issues can be reduced to reduce fluid friction loss, improve cooling performance, and improve cooling and heat transfer performance.

Embodiment 1
[0051] Figure 1 ~ Figure 2 It is a schematic diagram of the cross-section and the unfolded structure of the annular flow passage structure between the stator and the rotor of the shielded motor provided in Embodiment 1 of the present invention. Such as Figure 1 ~ Figure 2 As shown, the annular flow channel structure between the stator and rotor of the shielded motor provided by the present invention includes: a stator shielding sleeve (generally made of metal material) 3 with discontinuous flow guide ribs 2 on the inner cylindrical surface, and a discontinuous flow guide rib on the outer cylindrical surface. The rotor shielding sleeve (usually metal material) 4 of the rib 1, and the annular flow channel 5 between the stator shielding sleeve and the rotor shielding sleeve.
