Problems solved by technology

Therefore, in order to improve the cooling effect, evaporative cooling technology has been adopted in the cooling of the motor, but only the stator part, and the rotor part has to adopt other types such as air cooling method, so the structure of the motor is complex, the cooling is uneven, and the motor's It is difficult to further improve the performance

Embodiment Construction

[0032] The present invention is further described as follows in conjunction with accompanying drawing and embodiment:

[0033] Such as Figure 1-10 Shown: a kind of evaporative cooling propulsion motor of the present invention, it has a machine base 1, stator 2, rotor 3 and cooling system 4; Described cooling system comprises stator core and winding linear part cooling circuit 5: rotor and stator winding Cooling circulation loop 6: cooling medium liquid circulation loop 7; cooling medium vapor-liquid two-phase loop 8. The cooling circuit 5 of the stator core and the straight line part of the winding has a solid tooth pressure plate 5.2 of an integral solid structure for preventing the cooling medium liquid from passing through, and a hollow tooth of a hollow tooth pressure plate structure that can overflow when the liquid is filled higher than the winding Pressure plate 5.1: There is a liquid-passing groove plate 5.3, a liquid blocking block 5.4, and a ring rib 5.5 on the sta...

Abstract

The invention relates to an evaporative cooling propulsion motor, which belongs to the technical field of motor. The invention is particularly used as a propulsion motor with high power, great torque and low speed. The propulsion motor comprises a machine foundation, a stator, a rotor and a cooling system. The cooling system comprises a stator iron core, a winding straight portion cooling circuit, a rotor and stator winding cooling circulation circuit, a cooling medium liquid circulation circuit, and a cooling medium gas-liquid two-phase circuit. The propulsion motor has the advantages that: all internal heat of the motor is taken away by the vaporization latent heat of the cooling medium; a motor evaporative cooling circuit not only has all the advantages of water, hydrogen and air cooling, but also puts an end to the corrosivity of water cooling, the hydrogen explosion accident possibly caused by hydrogen cooling and the unevenness of air cooling; and the comprehensive performance of the motor is greatly improved.

Description

technical field [0001] The invention relates to an evaporative cooling propulsion motor, which belongs to the technical field of electric motors, and is particularly suitable for use as a propulsion motor with high power, high torque and low rotation speed. Background technique [0002] In the prior art, there are various types of motors, and their cooling methods are also different, but there are two principles from the perspective of heat absorption, one is to use the temperature rise of the cooling medium fluid itself to absorb the heat generated per unit time. To cool the motor, the other is to use the principle of cooling medium vaporization and heat absorption to cool the motor. The latent heat of vaporization per unit mass of cooling medium is dozens to hundreds of times of the heat taken away by its simple temperature increase. Therefore, in order to improve the cooling effect, evaporative cooling technology has been adopted in the cooling of the motor, but only the...
