BLDC ESC (Electronic Speed
Controller) is a device designed to control the speed, direction, and braking
of brushless DC motors. Essential for drones, RC vehicles, and robotics, it
ensures smooth operation and efficient power management with precise throttle
response.
Description:
A BLDC ESC (Brushless DC Motor
Electronic Speed Controller) is a circuit that controls the speed, direction,
and braking of a Brushless DC (BLDC) motor. Unlike traditional brushed motor
controllers, a BLDC ESC uses pulse-width modulation (PWM) signals and
field-oriented control (FOC) techniques to regulate motor operation
efficiently. It is widely used in drones, RC vehicles, electric bikes, and
industrial automation applications.
