Nowadays, many automation equipment manufacturers have begun to pay attention to brushless DC motors. They want to use brushless DC motors to replace induction motors, stepper motors, etc., which have many defects such as low efficiency, high noise, and high power consumption. Recently, ATO has also received many inquiries from new and old customers: Do BLDC motors and brushed DC motors both rotate when powered? Actually not. Brushless DC motors must be equipped with corresponding controllers to rotate. This is determined by the structural principle of the brushless dc motor.
