1 thought on “What is a brushless motor? What is the difference between no brush?”

Brushless brush -free DC motor is composed of motor main body and drive. It is a typical electromechanical integrated product. Because the brushless DC motor is running in a self -control type, it will not be launched on the rotor to the rotor on the rotor like the transition speed adjustment, and it will not cause oscillation and loss during load mutations. The permanent magnet of the brushless DC motor of small and medium-sized capacity is now mostly used with high magnetic energy-grade rare earth tin iron boron (ND-Fe-B) material. Therefore, the volume of the rare earth permanent magnetic brush -free motor is compared to the same capacity three -phase asynchronous motor to reduce a seat number. The brush -free motor and brush motor As the popularity of electric vehicles becomes higher and higher, the market competition is extremely fierce. In addition to making articles in product prices and appearance, many companies and businesses also Advertising on small details of electric vehicles, the most of which are brushing and brushless publicity for motors, and advertising of the brushless motor is one of the highlights. When you see this term, you can't help but think that since there is a brush, there must be a brush, so where is the difference between brush and brushlessness? The following editors will answer it for you. 1. When a brush motor is working, the coil and the directioner rotate, the magnetic steel and the carbon brush are not rotated, and the alternating changes in the direction of the coil current are completed by the conversioner and brush with the motor. In the electric vehicle industry, there are brush motors and high -speed brush motors and low -speed brush motors. There are many differences between brush motors and brushless motors. From the name, it can be seen that there are brush motors and carbon brushes. There is no carbon brush without a brush motor 2. Integrated electromechanical products. Because the brushless DC motor is running in a self -control type, it will not be launched on the rotor to the rotor on the rotor like a variable frequency speed adjustment. 3, a brush motor is a traditional product, and the performance is relatively stable.
The brushless motor is an upgraded product, and its life performance is better than that of brush motors. However, its control circuit is relatively complicated, and the requirements of the aging of components are relatively strict. Although the motor has a long life, the control circuit is prone to problems. Therefore, a brushless motor is selected to undergo strict reliability tests to ensure quality. However, with the continuous upgrade of technology, brushless motor technology has matured. 4. In the actual production process, because there are high -speed motors with a tooth DC motor, the gear teeth are small and easy to wear, but the power is large and the ability to climb is strong. The brushless DC motor saves the trouble of two or three years of carbon brushing during use. However, due to the process of controlling the brushless motor, the accuracy is extremely high. Moreover, the price of a brushless motor controller is also higher. In contrast, there is a toothless DC motor. Although it is necessary to replace the carbon brush, it is very easy to replace the carbon brush, and the control of the motor is relatively simple. The motor is stable and the safety factor is high. 5. There is a brush motor referring to the motor is DC electric input. The controller that controls it can only provide the speed to adjust the speed. Three -phase AC power, and the motor operates normally according to the sensor Hall component in the motor. Directly speaking, the brushless motor has a long life and power saving than the brush motor, but the controller costs higher than the brush controller. At present, the brushless controller is now eliminated. The electric vehicle controller is used to control the starting, operation, advance and retreat, speed, stop, and other electronic devices of the electric vehicle. It is like the brain of the electric vehicle and an important part of the electric vehicle.
