YX3 series high-efficiency energy-saving motors refer to general-purpose standard motors with high-efficiency motors. Starting from energy conservation and environmental protection, high-efficiency motors are the current international development trend. The United States, Canada, and Europe have successively promulgated relevant regulations.
At present, my country's motor power consumption exceeds half of the total power consumption, accounting for as much as 70% of the industrial power consumption. Therefore, to reduce energy consumption, there is a lot to do in the field of motors, and high-efficiency and energy-saving motors can be used as a breakthrough in energy conservation. The energy-saving effect of high-efficiency energy-saving motors is remarkable. Under normal circumstances, the efficiency can be increased by about 3%-5%. It can be seen that improving motor efficiency, reducing motor energy consumption, and developing and applying high-efficiency and ultra-efficient motors have very important national energy strategic significance and realistic social benefits. Accelerating the promotion and application of high-efficiency motors is of great significance to the completion of the "Twelfth Five-Year" energy saving and emission reduction tasks and the promotion of industrial structure adjustment and upgrading. At present, China's high-efficiency motor industry has formed a relatively complete industrial chain, and has mastered the production technology of high-efficiency and ultra-high-efficiency motors. China has unique conditions for mass production of high-efficiency motors.
The YX3 series of high-efficiency and energy-saving standard three-phase asynchronous motors produced by our company are squirrel-cage rotor three-phase asynchronous motors with constant speed manufactured by using new materials, new technology and optimized design. It is a new generation of energy-saving motors. YX3 motor has the characteristics of high efficiency, large starting torque, low noise, etc., and the structure is more reasonable. The cooling and heat dissipation conditions are mature. This series of motors are general-purpose three-phase asynchronous motors, which can be used to drive various general mechanical equipment, and are suitable for all places without special requirements and no speed change.

Electric motor, also known as motor or electric motor, is an electrical device that converts electrical energy into mechanical energy, and can then use 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.

Concept: DC motors refer to motors that use DC power sources (such as dry batteries, batteries, etc.); AC motors refer to motors that use AC power (such as household circuits, alternators, etc.).
Application: DC motors and AC motors have different structures. DC motors have a commutator (two opposite half copper rings), and AC motors do not have a commutator.
DC motors are generally used in circuits with low voltage requirements. DC power supplies can be easily carried. For example, electric bicycles use DC motors. For example, computer fans and radios are used.
Differentiating method: The most important thing depends on whether there is a commutator and what power supply is used. There is a DC motor with a DC power supply for the commutator.

The working principle of AC motor
At present, there are two types of AC motors commonly used: 1. Three-phase asynchronous motors. 2. Single-phase AC motor.
The first type is mostly used in industry, while the second type is mostly used in civilian electrical appliances.
1. Rotation principle of three-phase asynchronous motor
The prerequisite for the three-phase asynchronous motor to rotate is to have a rotating magnetic field, and the stator winding of the three-phase asynchronous motor is used to generate the rotating magnetic field. We know, but the voltage between the phase power phase and the phase is 120 degrees out of phase, and the three windings in the three-phase asynchronous motor stator are also 120 degrees out of each other in spatial orientation. Every time the current changes for one cycle, the rotating magnetic field rotates once in space, that is, the rotating speed of the rotating magnetic field is synchronized with the change of the current. The speed of the rotating magnetic field is: n=60f/P where f is the power frequency, P is the number of pole pairs of the magnetic field, and the unit of n is: revolutions per minute. According to this formula, we know that the speed of the motor is related to the number of magnetic poles and the frequency of the power supply. For this reason, there are two ways to control the speed of an AC motor: 1. Change the magnetic pole method; 2. Frequency conversion method. In the past, the first method was mostly used, but now the variable frequency technology is used to realize the stepless speed control of the AC motor.
2. Rotation principle of single-phase AC motor
Single-phase AC motors have only one winding, and the rotor is squirrel cage type. When a single-phase sinusoidal current passes through the stator windings, the motor will generate an alternating magnetic field. The strength and direction of this magnetic field change sinusoidally with time, but it is fixed in space, so this magnetic field is also called alternating. Pulsating magnetic field. This alternating pulsating magnetic field can be decomposed into two rotating magnetic fields with the same speed and opposite rotation directions. When the rotor is stationary, these two rotating magnetic fields produce two equal and opposite torques in the rotor, making the synthesis The torque is zero, so the motor cannot rotate. When we use external force to rotate the motor in a certain direction (such as clockwise rotation), the cutting magnetic field lines between the rotor and the clockwise rotating magnetic field become smaller; the rotor and the counterclockwise rotating magnetic field The movement of the cutting magnetic field lines becomes larger. In this way, the balance is broken, the total electromagnetic torque produced by the rotor will no longer be zero, and the rotor will rotate in the direction of pushing.


Three. Principle of Synchronous Motor
Synchronous motors are AC motors, and the stator windings are the same as asynchronous motors. Its rotor rotation speed is the same as the speed of the rotating magnetic field generated by the stator winding, so it is called a synchronous motor. Because of this, the current of the synchronous motor is ahead of the voltage in phase, that is, the synchronous motor is a capacitive load. For this reason, in many cases, synchronous motors are used to improve the power factor of the power supply system.
There are roughly two types of synchronous motors in structure:
1. The rotor is excited by direct current. The rotor of this kind of motor is shown in the figure. It can be seen from the figure that its rotor is made of salient pole type. The field coils mounted on the pole core are connected in series with each other and have alternating opposite polarities. And there are two lead wires connected to the two slip rings mounted on the shaft. The field coil is excited by a small DC generator or battery. In most synchronous motors, the DC generator is installed on the motor shaft to supply the excitation current of the rotor pole coil.
2. Synchronous motor whose rotor does not need excitation.
