A motor that prevents coil overload and ensures normal operation

Abstract

The invention discloses a motor for preventing coil overload and ensuring normal operation, which includes a motor casing, a heat dissipation working block is fixed on the top end surface of the motor casing, and a cooling device for heat dissipation when the inner wall of the motor is overheated is arranged inside the heat dissipation working block. Liquid-cooled heat dissipation mechanism, the motor housing is provided with a magnetic induction chamber, the bottom wall of the magnetic induction chamber is provided with a magnet slider chute, and the magnet slider chute is provided with a device for detecting the internal current of the motor. Current detection mechanism; the present invention uses two sets of cooling systems of air cooling and liquid cooling. When the traditional air cooling cannot effectively dissipate heat, the heat of the motor itself is used as the power to start the liquid cooling, so that the inner wall of the motor can quickly cool down, avoiding overheating and causing internal damage to the motor. Damage, while increasing the inspection of the motor coil current, avoiding the overload of the motor coil, and increasing the resistance in the circuit when overloaded, and starting the liquid cooling system to avoid burning the coil due to overload of the coil circuit.

Description

technical field [0001] The invention relates to the related fields of motors, in particular to a motor that prevents coil overload and ensures normal operation. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. As a power source for electrical appliances or various machines, its main function is to convert electrical energy into mechanical energy. [0003] At present, the heat dissipation device inside the motor is mostly the heat dissipation plate and the fan to complete the heat dissipation. When the motor is used for a long time, the single air-cooled heat dissipation effect is not good, and it is easy to cause overheating damage inside the motor. At the same time, the long-term use of the motor is likely to cause coil The internal current overload causes the coil to burn out. Contents of the invention [0004] The technical problem to be solved by the ...
