Motor maintenance means that motor failure often occurs due to long-term continuous use and improper operation of the user. Motor maintenance should be carried out by professional personnel to ensure that the motor runs well. Motor maintenance can save cost and improve the utilization rate of motor. Motor, also known as motor, is a kind of electromagnetic device which realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. If you want to do a good job in motor maintenance, you first need to understand the classification of motors.
1. Synchronous motor: can be divided into permanent magnet synchronous motor, reluctance synchronous motor and hysteresis synchronous motor.
2. Asynchronous motor: it can be divided into induction motor and AC commutator motor.
3. Induction motor: it can be divided into three-phase asynchronous motor, single-phase asynchronous motor and cover-pole asynchronous motor.
4. Ac commutator motor: it can be divided into single-phase series motor, AC / DC motor and repulsion motor.
5. DC motor:
1 classified according to structure and working principle.
It can be divided into brushless DC motor and brushless DC motor.
Brushed DC motor can be divided into permanent magnet DC motor and electromagnetic DC motor. Electromagnetic DC motor is divided into series excitation DC motor, parallel excitation DC motor, other excitation DC motor and compound excitation DC motor. Permanent magnet DC motor is divided into rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and Al-Ni-Co permanent magnet DC motor.
2 classified according to start-up and operation mode.
It can be divided into capacitive starting single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor starting and running single-phase asynchronous motor and split-phase single-phase asynchronous motor.
