How to choose a suitable motor
Electrical equipment that converts electrical energy and mechanical energy is collectively referred to as a motor. The motor uses the principle of electromagnetic induction to realize the mutual conversion of electrical energy and mechanical energy. A device that converts mechanical energy into electrical energy is called a generator, and a device that converts electrical energy into mechanical energy is called an electric motor.
Motor classification
Divided by the type of working power: can be divided into DC motor and AC motor.
1) DC motors can be divided according to structure and working principle: brushless DC motor and brushed DC motor.
Brushed DC motors can be divided into: permanent magnet DC motors and electromagnetic DC motors.
Electromagnetic DC motor division: series-excited DC motor, shunt DC motor, separately excited DC motor and compound excitation DC motor.
Permanent magnet DC motor division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and AlNiCo permanent magnet DC motor.
2) Among them, AC motors can also be divided into: single-phase motors and three-phase motors.
According to the structure and working principle, it can be divided into: DC motor, asynchronous motor and synchronous motor.
1) Synchronous motors can be divided into: permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors.
2) Asynchronous motors can be divided: induction motors and AC commutator motors.
Induction motors can be divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded-pole asynchronous motors.
The AC commutator motor can be divided into: single-phase series-excited motor, AC-DC motor and repulsive motor.
According to the starting and running modes, it can be divided:
Capacitor-starting single-phase asynchronous motor, capacitor-operated single-phase asynchronous motor, capacitor-starting single-phase asynchronous motor, and split-phase single-phase asynchronous motor.
It can be divided according to the purpose: drive motor and control motor.
1) Drive motor can be divided: electric tools (including drilling, polishing, polishing, grooving, cutting, reaming, etc.) with electric motors, household appliances (including washing machines, electric fans, refrigerators, air conditioners, recorders, video recorders) , motors, vacuum cleaners, cameras, hair dryers, electric razors, etc.) Motors and other general purpose small mechanical equipment (including various small machine tools, small machinery, medical equipment, electronic equipment, etc.).
2) The control motor is divided into: a stepping motor and a servo motor.
According to the structure of the rotor can be divided:
Cage induction motors (formerly known as squirrel-cage asynchronous motors) and wound rotor induction motors (formerly known as wound-type asynchronous motors).
