An electric motor, also known as a motor or an electric motor, is an electrical device that converts electrical energy into mechanical energy, and can then use the mechanical energy to generate kinetic energy to drive other devices. There are many types of motors, but they can be roughly divided into AC motors and DC motors for different occasions.
The advantage of a DC motor is that it is relatively simple in speed control. It only needs to control the voltage to control the speed. However, this type of motor is not suitable for operation in high temperature, flammable and other environments, and because the motor needs to use carbon brushes as a Commutator components (brush motors), so it is necessary to regularly clean up the dirt generated by carbon brush friction. A brushless motor is called a brushless motor. Compared with a brush, a brushless motor is less power-saving and quieter because of the less friction between the carbon brush and the shaft. The production is more difficult and the price is higher. AC motors can be operated in high temperature, flammable and other environments, and do not need to clean the carbon brush dirt regularly, but it is more difficult to control the speed, because controlling the speed of the AC motor needs to control the frequency of the AC (or use induction The motor uses the method of increasing the internal resistance to reduce the motor speed at the same AC frequency), and controlling its voltage will only affect the torque of the motor. Generally, the voltage of civil motors is 110V and 220V. In industrial applications, there are also 380V or 440V.
working principle
The principle of rotation of the motor is based on John Ambrose Fleming's left-hand rule. When a wire is placed in a magnetic field, if the wire is energized, the wire will cut the magnetic field line and move the wire. The electric current enters the coil to generate a magnetic field, and the magnetic effect of the electric current is used to make the electromagnet continuously rotate in the fixed magnet, which can convert electrical energy into mechanical energy. It interacts with a permanent magnet or a magnetic field generated by another set of coils to generate power. The principle of a DC motor is that the stator does not move, and the rotor moves in the direction of the force generated by the interaction. The AC motor is the stator winding coil is energized to generate a rotating magnetic field. The rotating magnetic field attracts the rotor to rotate together. The basic structure of a DC motor includes "armature", "field magnet", "snumeric ring", and "brush".
Armature: A soft iron core that can rotate around an axis is wound with multiple coils. Field magnet: A powerful permanent magnet or electromagnet that generates a magnetic field. Slip ring: The coil is connected to two semi-circular slip rings at about both ends, which can be used to change the direction of the current as the coil rotates. Every half a turn (180 degrees), the direction of current on the coil changes. Brush: Usually made of carbon, the collector ring is in contact with the brush in a fixed position to connect to the power source.
Basic structure
There are many types of electric motors. In terms of basic structure, its composition is mainly composed of a stator (Stator) and a rotor (Rotor).
The stator is stationary in the space, while the rotor can rotate around the shaft and is supported by bearings.
There will be a certain air gap between the stator and the rotor to ensure that the rotor can rotate freely.
The stator and the rotor are wound with coils, and current is applied to generate a magnetic field, which becomes an electromagnet. One of the stator and the rotor can also be a permanent magnet.
The following are all called motors
Classified by power supply:
name
characteristic
DC motor
Use permanent magnets or electromagnets, brushes, commutators and other components. The brushes and commutators continuously supply the external DC power supply to the coil of the rotor, and change the direction of the current in time, so that the rotor can follow the same direction Continue to rotate.
AC motor
The alternating current is passed through the stator coil of the motor, and the surrounding magnetic field is designed to push the rotor at different times and different positions to make it continue to run
*Pulse motor
The power source is processed by a digital IC chip and turned into a pulse current to control the motor. A stepping motor is a kind of pulse motor.

Its purpose is to achieve instant reversible characteristics by adding frictional load and reduce the effect of the induction motor. The amount of over-rotation generated by the force.
Stepping motor
It is characterized by a kind of pulse motor, a motor that rotates gradually at a certain angle. Because of the open-loop control method, it does not need a feedback device for position detection and speed detection to achieve precise position and speed control, and Good stability.

There are many electric uses, ranging from heavy industries to small toys. Different types of electric motors are selected in different environments. Here are some examples: wind-making equipment, such as electric fans, electric toy cars, boats and other elevators, elevators powered by electricity, such as underground railways, tram factories and hypermarkets Electric automatic doors, electric rolling shutters, and people's livelihood supplies on transport belt buses

The principle of a motor and a generator are basically the same, and the directions of energy conversion are different. The generator converts mechanical energy and kinetic energy into electrical energy through a load (such as water power, wind power). If there is no load, the generator will not have current flowing out. The cooperation of electric motors, power electronics, and micro-controllers has formed a new discipline called motor control. Before using the motor, you need to know whether the power source is DC or AC. If it is AC, you also need to know whether it is three-phase or single-phase. Connecting the wrong power supply will cause unnecessary losses and dangers. After the motor is rotated, if the load is not connected or the load is light so that the motor speed is fast, the induced electromotive force is stronger. At this time, the voltage across the motor is the voltage provided by the power supply minus the induced voltage, so the current is weakened. If the load of the motor is heavy and the speed is slow, the relative induced electromotive force is smaller. Therefore, the power supply needs to provide a larger current (power) to output/work corresponding to the larger power required.
Output: Refers to the work that the motor can perform in a unit time, and is determined by the motor's operating speed and torque. Rated output: The motor can exert its best characteristics under rated voltage and rated frequency, and continuously produce various energy outputs, such as operating speed or torque. Usually, the rated output value is indicated on the motor nameplate. Asia usually uses watts (W) as the unit, while Europe and the United States use horsepower (HP).
