In the industrial field, DC brushless motor is one of the commonly used accessories, and there are many electrical appliances around us equipped with DC brushless motor. Simply speaking, DC brushless motor is a kind of synchronous motor, which consists of motor main body and driver. It can control and maintain a certain speed when the load changes in the rated load range, but it must be controlled with brushless motor. The following is a detailed analysis of Lingchuang Power:
Reason 1: DC brushless motor belongs to the category of permanent magnet brushless synchronous motor. Its functional parameters, model, power supply voltage, output power, phase angle, presence or absence, photoelectric switch or self-identification function must be used in conjunction with the brushless motor controller in order to use normally.
Reason 2: Brushless DC motor has no brush and commutator, so to maintain the direction of rotation, it is necessary to have electronic commutator. The electronic commutator is controlled. At the same time, the brushless motor controller can also control the starting and stopping of the motor, positive and negative inversion, speed regulation, over-voltage, over-current and under-voltage protection. So there must be a brushless motor controller, even if the brushless DC motor is directly powered on is useless.
Above is the reason why brushless DC motor should cooperate with motor controller. How to choose brushless motor controller? In fact, it is very simple. First, it depends on whether it is a brushless motor controller. Second, it determines the voltage. There are 24V, 36V, 48V and 60V in the market. Third, it is better to buy a larger brushless motor controller than a smaller one.
