The nickname of carbon brush motors is a motor brush. It is a collective name for the carbon brush of the generator and the carbon brush of the motor.The appearance of the motor carbon brush on the outer appearance is especially like the rubber strip on the pencil. In addition, there are a small amount of wires on its top, and its volume is large and small.The main role of its motor is to change the direction of the current. The motor can be divided into AC motors and DC motors in the way it changes the direction of the current.
Carbon brush motor life
The carbon brush motor can reach 2000h in a good direction, but under extreme conditions, it may only be 100h, and it can generally reach the life of 1000H-3000H.So the environment used is important.In addition, it is also related to the material of the brush. The service life of the metal brush is better than the carbon brush.The overall level of the country is indeed lower than foreign countries.Generally in 1000H.Some do it well. I used a motor before, and the life can reach 2000h.
Carbon brush machine price
The first is JP Morgan carbon brush motor: This motor carbon brush belongs to the Morgan brand. The carbon brush is also called a brush. It is a sliding contact device, which is generally used in electrical equipment.There are three main materials for motor carbon brushes in the product, including metal graphite, galgling, and graphite.As a motor or device transmitting energy in an engine, it is generally made of a blocks made of coagulant.It is generally fixed on the shaft of the metal bracket, and the electrical energy uses the phase replacement to better transport the phase replacement to the coil. Because its main component is carbon, it is easy to wear during use.For it easy to wear this characteristic, we should regularly maintain and replace it and clean up its carbon accumulation in a timely manner. His general market sales price is 14.2 yuan.The second model is the DC carbon brush motor: This motor carbon brush is to stack the external current through the carbon brush to superimposed to the rotating rotor to play the role of input current.The advantages and disadvantages of carbon brushing directly determine the service life of the motor. Although they look the same on the outside, the copper powder alloy content contained in high -quality carbon brushes is relatively high, and its conductive performance is better than the average numberThe inferior products are much better.This motor carbon brush has good copper powder alloy content and conductive performance. Its market sales price is 5 yuan.
Carbon brush motor principle
Due to the rotation of the carbon brush motor, the brush is always rubbed with the conversion ring, and the electric spark is burned at the moment of the conversion, so the brush is a vulnerable part in the DC motor.In order to improve the service life, operating stability of DC motors, and reducing the noise and electromagnetic interference of DC motors, the brushless DC motor has gradually replaced the trend of brushing motors.
