Problems solved by technology

The electric vehicle motor protection equipment in the above-mentioned patent has the following disadvantages: the heat-absorbing coating is used to quickly suck out the heat in the shell, but if the external environment is high, the heat-absorbing coating can also reversely absorb the external heat into the shell, As a result, the temperature in the shell increases rapidly, which affects the service life of the motor

Abstract

The invention discloses a protection method and protection equipment for an electric vehicle motor, and relates to the technical field of motor protection. The problem that the heat dissipation efficiency is not high is solved. The protection equipment comprises a shell, and an anti-corrosion layer is arranged on the outer wall of the shell; an elastic layer is arranged on the inner wall of the shell, and an inner shell is arranged on the inner wall of the elastic layer; an air inlet is formed in the outer wall of one side of the shell, a filter screen is arranged on the inner wall of one side of the air inlet, and a waterproof breathable film is arranged on the outer wall of one side of the filter screen; the outer wall of one side of the shell is connected with a water tank through a fixing plate. The protection method of the protection equipment comprises the following steps that the box door is pulled, the moving distances of the three sliding rods in the three limiting boxes are adjusted, and the motor is arranged in the adjusting installation structure on the reinforcing plate to be fixed. Dry cold air flows through the space of the inner shell, so that the motor is cooled, heat generated in the motor is dissipated from the heat dissipation opening, and the service life of the motor is effectively prolonged.

Description

Technical field [0001] The present invention relates to the field of motor protection, in particular, to a protective method for electric vehicle motor and its protective equipment. Background technique [0002] The motor refers to an electromagnetic device that implements electrical energy conversion or transmission based on electromagnetic induction. Its main function is to generate drive torque as a power source of electricity or various mechanical. The motor is widely applied. When driving the electric vehicle, it is easy to be affected by the external environment due to the strict fitting of the motor structure, so it is necessary to set a protective device, and it is easy to produce due to the support of load and speed. Higher temperatures, therefore needs to be added. The existing motor heat dissipation device is mostly open or increasing the heat dissipation fans inside the guard, which is too simple, and cannot be effectively dissipated while protecting the motor, which ...
