A dry and wet dual-purpose high-efficiency running motor and its method and application

Abstract

The invention discloses a dry-wet dual-purpose high-efficiency running motor, a method and an application thereof, and belongs to the technical field of motors. It includes: an air-cooling mechanism arranged at the rear end of the motor casing; the air-cooling mechanism is configured to realize heat dissipation by increasing the airflow near the motor casing; a liquid cooling mechanism is arranged at the motor casing The inner wall of the motor; the liquid cooling mechanism is set to dissipate heat from the motor housing and the motor body through flowing water or oil; when in use, based on the environment where the motor is located, the work of the air cooling mechanism or the liquid cooling mechanism is individually controlled status, to realize switching and selection between air-cooled heat dissipation mode and liquid-cooled heat dissipation mode. The present invention also ensures the sealing performance in the water environment under the precondition of satisfying the high-efficiency heat dissipation of the water environment and the air environment at the same time. Based on the simultaneous satisfaction of heat dissipation requirements and sealing requirements, the performance of the motor is greatly improved, and the motor can achieve continuous 24-hour high-efficiency operation in any environment.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a high-efficiency running electric motor for wet and dry use, a method and an application thereof. Background technique [0002] According to the market demand, the use environment of the motor is gradually extended from the more common air environment to the water environment, and in more cases, the motor will meet the long-term and high-efficiency requirements of the water and the atmosphere due to the particularity of the use environment. work performance. However, it is difficult for the motors in the prior art to have the above performances: that is, it is impossible to achieve efficient operation in the air while also achieving efficient operation in the water. The reason is that the motor needs to generate heat and It is unavoidable, so heat dissipation is very important. However, the heat dissipation method in the atmosphere is different from the hea...

However, it is difficult for the motors in the prior art to have the above performances: that is, it is impossible to achieve efficient operation in the air while also achieving efficient operation in the water. The reason is that the motor needs to generate heat and is unavoidable, so heat dissipation is very important

However, the heat dissipation method in the atmosphere is different from the heat dissipation method in water, and the motors in two different environments cannot be used in common.
