Brushless motor (刷)Becoming more and more popular in our daily application, such as HVAC, electric cars, white goods, and industrial applications. It helps to electronic equipment is more reliable and durable. The advantages of brushless motor, can be summed up in three sentences. The first advantage of the brushless motor is efficiency. Because brushless motor can rotate force (in its biggestTorque)Under continuous rotation. Compared with them, there are only in some point of the rotating brush motor provides maximum torque. Despite the brush motor can provide the same torque as the brushless motor, but there is need greater magnetic brush motor, which means that the smaller size of the brushless motor can provide considerable power. Another advantage is controlled brushless motor. Feedback system can be used to control brushless motor, in order to provide the required torque and rotational speed. If brushless motors powered by batteries, the precise control can reduce the energy consumption and heat loss, helps to extend battery life. Brushless motor without brush can provide high durability and low electrical noise. For a brush motor, the brush and commutator, due to the movement of the continuous contact wear and may produce a spark in the contact. In particular, the spark gap in the brush through commutator usually produce, strong spark can cause electrical noise. If the motor electrical noise factors in the design, brushless motor is preferable.
