How many types of motors are there and what are the two types of motors

Classification according to the working power supply According to the different working power sources of the motor, it can be divided into DC motor and AC motor. Among them, AC motors are also divided into single-phase motors and three-phase motors. 2 Classification according to structure and working principle According to the structure and working principle, motors can be divided into DC motors, asynchronous motors and synchronous motors.

Synchronous motors can also be divided into permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded pole asynchronous motors.

AC commutator motors are further divided into single-phase series motors, AC and DC motors and repulsion motors. According to the structure and working principle, DC motors can be divided into brushless DC motors and brushed DC motors. Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors.

Electromagnetic DC motors are further divided into series excited DC motors, parallel excited DC motors, separately excited DC motors and compound excited DC motors. Permanent magnet DC motors are further divided into rare earth permanent magnet DC motors, ferrite permanent magnet DC motors and alnico permanent magnet DC motors. 3 Classification according to starting and operation mode Motors can be divided into capacitive starting single-phase asynchronous motors, capacitor-operated single-phase asynchronous motors, capacitor-starting single-phase asynchronous motors and split-phase single-phase asynchronous motors.

4 Classification by use According to the use, the motor can be divided into the drive motor and the control motor. The motor used for driving is divided into electric tools (including drilling, polishing, polishing, slotting, cutting, reaming and other tools) for electric motors, home appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, video players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.) motors and other general small mechanical equipment (including various small machine tools, small machinery, medical equipment, electronic instruments, etc.) electric motors.

There are two kinds of motors: DC motor and AC motor, according to the way of work, DC motor can be divided into series, parallel and double excitation, according to the structural form can be divided into brushed and brushless; AC motors are divided into three-phase and single-phase according to the working power supply, and are divided into wire-wound type and squirrel cage type according to the structural form. AC and DC motors are divided into too many according to their working characteristics, such as stepper motors, servo motors, shaded pole motors, synchronous and asynchronous motors, and speed-regulating motors, ......There are no less than dozens.

What are the two types of electric motors?According to the type of working power supply: it can be divided into DC motor and AC motor.

DC motors can be divided into brushless DC motors and brushed DC motors according to their structure and working principle.

Brushed DC motors can be divided into: permanent magnet DC motors and electromagnetic DC motors.

Ferrite permanent magnet DC motors and Alnico permanent magnet DC motors.

Among them, AC motors can also be divided into: single-phase motors and three-phase motors.

According to the type of working power supply: it can be divided into DC motor and AC motor.

1. A DC motor is a motor that converts DC electrical energy into mechanical energy. Because of its good speed regulation performance, it has been widely used in electric drag. According to the excitation mode, DC motors are divided into three categories: permanent magnet, separate excitation and self-excitation, of which self-excitation is divided into three types: parallel excitation, series excitation and compound excitation.

2. AC motor is a machine used to realize the mutual conversion of mechanical energy and AC electric energy. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have simple structure, easy to manufacture, and relatively firm, and are easy to make motors with high speed, high voltage, high current and large capacity because there is no commutator (see commutator for DC motors).

Extended Information: How DC Motors Work:

The direction of the force on the conductor is determined by the left-handed rule. This pair of electromagnetic forces forms a moment acting on the armature, which is called electromagnetic torque in a rotating electric machine, and the direction of the torque is counterclockwise, in an attempt to make the armature rotate in a counterclockwise direction. If this electromagnetic torque can overcome the resistance torque on the armature, such as friction and other load torques, the armature can rotate in a counterclockwise direction.

DC motor is an electric motor that relies on DC working voltage to operate, and is widely used in tape recorders, video recorders, DVD players, electric shavers, hair dryers, electronic watches, toys, etc.

The electric motor, commonly known as the motor, is an electromagnetic device for the conversion and transmission of this electrical energy. The electric rubber machine is mainly used as the power source of electrical appliances and various machinery by driving torque. Since the advent of the electric motor, it has been widely used in various places and equipment.

The classification of electric motors is as follows:

1. According to the working power supply of the motor, it can be divided into: DC motor and AC motor.

2. According to the structural principle of the motor, it can be divided into: DC motor, asynchronous motor and synchronous motor.

3. According to the electric start-up and operation closure mode, it can be divided into: capacitor starting single-phase asynchronous motor, capacitive running single-phase asynchronous motor, capacitor starting single-phase asynchronous motor and split-phase single-phase asynchronous motor.

4. According to the use of the motor, it can be divided into: drive motor and control motor.

5. According to the structure of the rotor: cage induction motor and wound rotor induction motor.

6. According to the running speed: high-speed motor, low-speed motor, constant-speed motor, speed-regulating electric car. Low-speed motors are further divided into gear reducer motors, electromagnetic reducer motors, torque motors and claw pole synchronous motors.
