How does the Motor Magnetic Tile Affect the Motor Performance?

1. The action and type of motor magnetic tile

The motor refers to the conversion of electrical energy to mechanical energy device, and the motor magnetic tile is an important part of the motor, its role is to generate a magnetic field, so as to realize the rotation and work of the motor. It is an important element in the motor that produces a magnetic field. When the motor is energized, the current flows through the motor coil, creating a magnetic field. This magnetic field is acted on by the motor magnetic tile, thus becoming more powerful and stable, enabling the motor to achieve higher working efficiency. It can generate a torque through a magnetic field interaction. The motor needs to produce torque to twist, which requires the motor magnetic tile to produce torque under the action of magnetic field. By controlling the change of current, magnetic field and other parameters, the size and direction of the torque produced by the motor magnetic tile can be controlled, so as to realize the operation and control of the motor. It can improve the efficiency of the motor. High efficient motors can not only reduce energy waste, but also reduce loud noise, generate less vibration and so on. Through continuous optimization and improvement, the efficiency of the motor can be improved, so as to achieve a more economical and energy-efficient motor system. Common magnetic tile materials include iron oxide, cadmium oxide, ferrite, ndfeb, etc. Different magnetic tile materials have different effects on motor performance. Common have permanent magnet, electromagnet, electromagnetic aluminum and so on. Permanent magnet is a very common motor magnetic tile, it is composed of iron, nickel, cobalt, aluminum, samarium, europium, gadolinium and other elements. Its role in the motor is to produce a constant magnetic field and is therefore particularly suitable for motors that require frequent operation. Electromagnet is an important motor magnetic tile, through the input current, can change the distance between the core and the coil. Its role in the motor is very critical, especially suitable for the motor that needs rapid rotation and stop. Electromagnetic aluminum is a new type of motor magnetic tile, very suitable for high speed, high temperature, high humidity and other environments of the motor. In the motor, it can produce a large amount of magnetic energy, thus driving the normal operation of the motor.

2. The influence of the magnetic field shape on the motor performance

The shape of the magnetic field of the motor is divided into radial and axial directions. The radial and axial distribution of the magnetic field will directly affect the internal structure of the motor and the size of the electromagnetic torque. Generally speaking, the radial magnetic field shape of the motor has a great influence on the motor performance. Under the action of radial magnetic field, the torque and speed of synchronous motor and assynchronous motor will change. When the radial distribution of the magnetic field is uniform, the torque and power of the motor will be more stable, and the efficiency of the motor will also be higher. In addition, in the case of uneven distribution of radial magnetic field, the "leakage" between the electrodes of the motor, which results in the efficiency of the motor, and aggravates the vibration and noise of the motor. Radial magnetic field motor can improve the mechanical output power and efficiency, while axial magnetic field motor can improve the torque and starting torque. The axial magnetic field will directly affect the mechanical structure and torque size of the motor. When the axial magnetic field is evenly distributed, the vibration and noise of the motor will be reduced, and the torque and efficiency of the motor will be higher. However, if the axial magnetic field is not evenly distributed, it will cause the motor torque instability, and may also cause the wear and damage of the motor.

3. The effect of the magnetic pole number

The number of magnetic poles of the motor is closely related to the shape of the magnetic field. Different number of magnetic poles will produce different magnetic field shapes, which affects the performance of the motor. In general, the more magnetic poles, the lower the motor speed, but the torque and efficiency will increase; the opposite is true. In the permanent magnet DC motor, the larger the number of magnetic poles, the higher the torque density of the motor, and the higher the speed. With the rotation of the permanent magnet ferromagnetic field, the electric opportunity constantly produces the electromotive force, so that the motor produces electromagnetic suction, in turn will produce torque, so that the motor rotation, each magnetic pole will produce electromagnetic suction. Therefore, an increase in the number of magnetic poles leads to an increase in the average electromagnetic suction of the motor, which increasing the torque density of the motor. The rotational speed of the motor is also affected by the number of magnetic poles. Usually, the more the poles, the faster the motor is. This is because as the speed of the motor increases, the rotation speed of the magnetic field also increases, and at high speeds, the motor needs a high electromotive force to maintain normal operation. Therefore, at high speeds, the motor needs more number of magnetic poles to meet the electroF requirement.

4. Material selection of the motor magnetic tile

The material selection of the motor magnetic tile also has a great impact on the motor performance. When choosing magnetic tile materials, its magnetic properties should be considered first, such as coercivity, magnetic conductivity, coercive magnetic field strength, etc. These indicators directly affect the output power and efficiency of the motor. At the same time, the physical and chemical properties of the material should also be considered, such as density, thermal expansion coefficient, wear resistance, high temperature resistance, etc. These attributes will affect the service life and performance stability of magnetic tiles. There are three common kinds of magnetic tile materials: aluminum, nickel and cobalt magnet, permanent magnet ferrite, and NdFeB magnet. These materials have different magnetic properties, physical and chemical properties and are suitable for different motor types and working environments. When the motor is required to have strong magnetism, ndfeb magnetic tile can be selected. This material has strong magnetic force and can be used to manufacture high-performance motors. Ndfeb is not the cost and manufacturing process of priority. For low-pressure power motors, ferrite magnetic tiles can be used as a substitute.
