BLDC controllers are electronic motor controllers that use pulse width modulation (PWM) to control the speed and torque of an electric motor. They are used in various applications, including electric vehicles, drones, and robotics. Controllers are a vital component of any BLDC motor system.
What should I know about this?
Controllers typically have three phases, each of which controls one winding of the BLDC motor. The controller uses PWM to switch the phases on and off in a specific sequence, which creates a rotating magnetic field that drives the BLDC motor. The speed and torque of the BLDC motor can be controlled by changing the duty cycle of the PWM signal.
Controllers typically include several safety features, such as over-current protection, short-circuit protection, and thermal protection. They may also include features such as regenerative braking and programmable speed profiles. Controllers are available in various sizes and configurations to suit different applications.
