[0002] For water-cooled motors with high power density and compact structure, in order to effectively remove the heat generated by the windings when the motor is running, improve the service life of the bearings, and at the same time achieve the motor performance indicators, the cooling of the motor is crucial; the heat generated by the motor is almost all transferred to the base through the stator core and carried away by the water circulation of the base shell, while the heat generated by the stator winding ends and the rotor does not contact the stator core, and only a part of the heat is transferred through the internal air and the stator-rotor air gap, which cannot achieve a good cooling effect, so that the motor ends cannot be well cooled, resulting in an increase in motor temperature.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below in conjunction with the accompanying drawings. As shown in the figure, the present invention includes a base 6, both ends of which are connected to a front cover 4 and a rear cover 7, the front cover 4 is connected to a front outer cover 2, and the rear cover 7 is connected to a rear outer cover 8; the front outer cover 2 and the rear outer cover 8 are both buckled on the radial outer end of the rotating shaft 1; the front cover and the rear cover are both provided with bearings, and the rotating shaft is provided on the bearings; Figure 2 As shown, water channels are arranged inside the machine base 6, the front cover 4, the front outer cover 2, the rear cover 7, and the rear outer cover 8 to form a water circulation channel; the water inlet and the water outlet of the water circulation channel are arranged on the machine base.

[0020] The base, front cover, front outer cover, rear cover, and rear outer cover are all provided with matching water inlets, and the matching water inlets are provided with concave or convex buckling structures, and sealing gaskets 5 are also provided between adjacent matching water inlets and embedded in the buckling structures. Figure 8 As shown, taking the connection between the front end cover 4 and the machine base 6 as an example, the front end cover 4 is provided with a protrusion 41, and the machine base 6 is provided with a groove 61, and the protrusion 41 matches with the groove 61 to form a matching water outlet.

[0021] Preferably, the cooling water flows into the machine base and then flows out through the front end cover, the front outer cover, the front end cover, the machine base, the rear end cover, the rear outer cover, the rear end cover, and the machine base in sequence.

[0022] Another cooling water circulation method is: with the machine base as the starting point and the end point, separate circulation loops are set up respectively, that is, the machine base, front cover, and front outer cover are one group of circulation loops, and the machine base, rear cover, and rear outer cover are another group of circulation loops. This circulation method can increase the number of water circulations and achieve better cooling effect.

[0023] In order to prevent the sealing of the matching water outlet from being affected during tightening, the matching water outlet and the fixing screws are arranged on the same circumference.

[0024] Example 1

[0025] In order to increase the amount of water flowing, two water inlets are processed side by side. The number of water inlets can also be designed according to the space. The connection between the machine base and the water inlets of the front and rear end covers is a flat surface with a stopper. A groove is processed at the water inlet position of the machine base. A sealing groove is processed on the outside of the groove. A sealing gasket is placed to seal the waterway connection. Bosses are processed at the water inlets of the front and rear end covers to position and prevent stringing. The bosses and grooves here cooperate with each other to form a matching water inlet. In addition, bolts are used to fix the middle position of the water inlet to increase the stability of the plane matching. The connection between the front and rear end covers and the front and rear outer covers is a flat surface. A sealing groove is processed at the water inlet position of one of the components, and a sealing gasket is placed to seal the waterway connection. The water inlet and outlet are determined according to the location of the water source and can be used interchangeably. Taking the figure as an example, the solid arrow indicates the direction of internal coolant circulation, and the dotted arrow indicates the direction of the water path at the junction of the two components. The coolant enters the water channel of the machine base through the water inlet and circulates inside, enters the front cover water inlet 105 from the water inlet 101, circulates to the water inlet 6 106 on the other side, and then enters the front outer cover through the water inlet 9 109 for circulation. After the circulation, it goes out through the water inlet 10 110, and then enters the front cover through the water inlet 7 107. After the circulation, it goes out through the water inlet 8 108. At this time, the coolant passes through the water inlet again. The water enters the water channel of the machine base through the water port two 102 for circulation, goes out through the water port three 103 after circulation, enters the rear end cover through the water port eleven 111, goes out from the water port twelve 112 after circulation, and enters the rear outer cover through the water port fifteen 115, goes out from the water port sixteen 116 after circulation, enters the rear end cover for circulation through the water port thirteen 113, then goes out through the water port fourteen 114, enters the water channel of the machine base through the water port four 104, and goes out through the water outlet of the machine base, completing the whole large cycle and fully taking away the internal heat of the motor.
