Answer：The main applications of high-power brushless DC motors in the automotive industry include wheel drives, air-conditioning compressors, air-conditioning blowers, purifiers, air extractors, etc.
Answer：The no-load torque of a brushless motor is determined by various no-load losses of the motor. If the no-load torque is large, the no-load loss of the motor will be large, which will affect the extreme efficiency of the motor and the position of the e...
Answer：many automation equipment manufacturers have begun to pay attention to brushless DC motors, replacing previous motors with many insurmountable defects such as low efficiency, high noise, and high power consumption, such as AC induction motors, steppe...
Answer：The Hall integrated circuit is based on the principle of the Hall effect and is made using integrated packaging and assembly processes. It integrates Hall elements and necessary peripheral circuits. It can easily convert magnetic field signals into l...
Answer：Brushless DC motors can achieve start-stop control by turning the power on or off just like brushed DC motors. This control method is usually accomplished directly using a contact switch. The disadvantage of this method is that the starting current i...
Answer：When the brushless DC motor is working, it will cause commutation torque fluctuations. How to suppress the torque fluctuations? The following editor will introduce several methods to suppress the torque fluctuations caused by current commutation.
Answer：There are many reasons for the torque fluctuation of brushless DC motors, which can be divided into the following aspects: torque fluctuation caused by the electromagnetic torque generation principle, torque fluctuation caused by current commutation,...
Answer：The brushless motor removes the brush. The most direct change is that there is no spark generated when the brushed motor is running, which greatly reduces the interference of sparks to remote control radio equipment.
Answer：Brushless motors use square wave self-controlled permanent magnet synchronous motors, which are very similar to three-phase asynchronous motors and have great advantages in performance; brushless motors have low interference, low noise, and long life...
Answer：With the rapid development of power electronics technology and new semiconductor devices, AC speed control technology has been continuously improved and improved. The gradually improved frequency converters have been widely used in AC motors with the...
