Abstract
The invention discloses an automatic cooling system for a motor and belongs to the field of motor devices. The automatic cooling system for the motor solves the problem that in the prior art, a motor cannot be automatically cooled or work continuously. The automatic cooling system for the motor mainly comprises an air-water cooling machine, a PLC system, a frequency converter, a variable-frequency motor, a draught fan and the like. A temperature sensor is arranged in the air-water cooling machine. The temperature sensor sends environment temperature signals to the PLC system. When the temperature exceeds a preset temperature, the PLC system sends control signals to the frequency converter, and the frequency converter changes the work frequency of the variable-frequency motor connected with the frequency converter, the variable-frequency motor drives the draught fan to feed cold air in the air-water cooling machine into a direct-current motor, and then the cooling effect is achieved. By the adoption of the automatic cooling system, the normal work of the motor is guaranteed, automatic control is achieved, the system is simple and practical, the service life of the motor is prolonged, and the level of equipment automatic and mechanical operation is improved.
