Water cooling motor

Abstract

The invention provides a water-cooled motor, which includes a base, a housing fixed on the base, a front end cover and a rear end cover, the housing, the front end cover and the rear end cover form an inner cavity through which The front end cover and the rear end cover are provided with a rotating shaft, and a rotor is installed on the rotating shaft, and a stator is arranged around the rotor in the inner cavity, and the stator is arranged in close contact with the outer shell, and the rotor and There is a gap between the stators, and it is characterized in that: the front end cover is provided with an air inlet, the rear end cover is provided with an air outlet, and a heat dissipation device is provided, and the heat dissipation device includes a water cooling element, and the water cooling The component includes a first water-cooling part that is attached to the shell and a second water-cooling part that is in contact with the outer surface of the rear end cover, and a fan fixed on the rotating shaft is sequentially provided outward from the second water-cooling part and fan cover.

Description

technical field [0001] The invention relates to the field of motors, in particular to a water-cooled motor. Background technique [0002] Motors have a wide range of applications. Especially in recent years, as my country promotes the transformation and upgrading of the manufacturing industry, in various intelligent manufacturing fields, automation equipment powered by motors and driven by motors is becoming more and more automated. Under this trend, equipment in various industries has higher and higher requirements for motors, such as high efficiency and high power density. However, during the long-term operation of the motor, the temperature rise problem often restricts the efficient operation of the motor, and further reduces the service life of the motor. [0003] The reasons for the heat generated during the working process of the motor include bearing friction, coil resistance, iron core reluctance, etc. When the temperature of the motor is too high, it will cause the...

AI Technical Summary

Problems solved by technology

The stator winding of the motor is not in direct contact with the casing and the end cover, and there is air in the middle, and the heat transfer coefficient of the air is very low, and the heat transfer capability is very poor. The stator winding only contacts the stator, so its heat can only be conducted to the stator first. , and then transmitted to the outer casing by the stator, so that when the motor is working, the temperature of the casing is not high, but the internal temperature of the motor is still very high

Therefore, some motors have air inlets and air outlets on the front end cover and rear end cover, and cooperate with the fan outside the rear end cover to dissipate heat from the motor. In addition, the heat dissipation effect of the motor shell is not ideal
