Brushless DC motor consists of a motor body and a driver, and is a typical electromechanical integrated product. Brushless DC motors have the characteristics of fast response, large starting torque, and the ability to provide rated torque from zero speed to rated speed. However, the advantages of brushless DC motors are also their disadvantages, because DC motors need to generate constant torque under rated load. The stator winding of the motor is mostly made into a three-phase symmetrical star connection, which is very similar to three-phase asynchronous motors. Next, let's introduce the four major advantages of brushless DC motors.
1. Brushless DC motors have a small volume and light weight. Brushless DC motors have a long service life, usually more than 10 times that of brushed motors, but if they break down, they need to be replaced. However, they do not require maintenance in daily life, making them easy to repair and maintain.
2. The higher efficiency of brushless DC motors is due to the use of permanent magnets and the loss of magnetic cores in the rotor. At the same time, the use of permanent magnets in ventilator motors can reduce motor maintenance and extend the service life of the motor.
3. Low noise, brushless DC motor without brushes, greatly reduces friction during operation, runs smoothly, has much lower noise, and has low vibration, no sparks, high reliability, good stability, and strong anti-interference ability.
4. The brushless DC motor operates in an automatic control mode, which will not cause oscillation or step loss when the load suddenly changes. By using appropriate transformation algorithms, the thermal performance of the motor can be improved, the speed range and response time of the motor can be enhanced, better electromagnetic isolation can be achieved, and torque response can be improved.
In summary, there are many advantages to brushless DC motors. Welcome to come and purchase.
