1, topic: causes of motor damage of electromechanical equipment and its maintenance and prevention.

2. Abstract: In modern industrial production, motor is the mechanical power output source of mechanical and electrical equipment. In actual production, the motor breaks down, which affects the use efficiency of mechanical and electrical equipment. Why the motor breaks down and how to maintain and prevent the motor from breaking down are problems worthy of consideration and solution.

3. The working principle of the motor is that a rotating pair is formed between the rotor and the stator, and the electromagnetic force on the wire wound on the rotor forms an electromagnetic torque on the rotating center line of the rotating pair to drive the rotor to rotate. The output of the motor is rotation, so it is called rotating motor (referred to as rotating motor).

4. If the motor is cut along its radial direction, the rotor and stator are unfolded into a straight line, which are called primary side and secondary side respectively. Then the rotating pair between the rotor and the stator becomes a moving pair, the relative motion between the primary side and the secondary side becomes a linear motion, and the output of the motor is a linear motion. So this kind of motor is called linear motor.

5. Motors are widely used in modern mechanical and electrical equipment. Machine tool, water pump, belt conveyor, fan, etc. Need motor drive; Electric locomotives and elevators need motor traction. Electric fans, refrigerators, washing machines and even various motor toys in family life are inseparable from motors.

6. Motors have been applied in all aspects of modern social life. The failure of motor in electromechanical equipment directly affects the efficiency of the equipment. So what is the cause of motor failure and how to maintain it? What about preventing failure?
