Exceed RC Brushless Speed Controllers
Brushless Speed Controls (ESC)
A brushless motor controller or brushless ESC (Electronic Speed Control) is
used to vary the speed of a brushless motor. These function as an interface
between the brushless motor and the battery (click
lipo batteries). Controlled by the throttle signal from an
RC receiver, the brushless ESC provides
variable power to the motor allowing proportional speed adjustments.
Unlike a brushed motor, power cannot be directly
applied to a brushless motor. Instead, the speed control intelligently
powers each phase of a brushless motor in sequence, causing it to rotate.
Brushless speed controls have three motor wires, allowing them to connect to
standard three phase brushless motors. A brushed speed control (with two
motor wires) cannot be used to power a brushless motor.
