Q: Do you need a electronic speed controller for a brushless motor?

A: Yes, to operate a bldc motor almost always require a dedicated speed controller, also known as an electronic speed controller (ESC) or driver. These controllers are necessary to regulate the voltage and current delivered to the motor's windings, enabling precise control over speed, direction, and torque.
