Tips: Why do brushless DC motors need to be equipped with a BLDC controller?

The brushless DC motor replaces the mechanical commutator with an electronic commutator. Because of the electronic commutation, the brushless DC motor needs a driver-drive circuit. The commutation circuit of a brushless DC motor is composed of two parts: drive and control. The two parts are not easy to separate. In particular, low-power circuits often integrate the two into a single application-specific integrated circuit.

Brushless DC motors do not have brushes and commutators, so if you want to maintain the direction of rotation, you must have an electronic commutator. The electronic commutator is controlled by the driver. At the same time, the brushless motor controller can also control the start and stop of the motor, forward and reverse rotation, speed adjustment, overvoltage, overcurrent, and undervoltage protection. So there must be a brushless motor controller, even if the DC brushless motor is directly energized, it will not work.
