Hobbywing Speed Sensor brushless motor rpm sensor for high voltage ESC

The RPM sensor is an accessory of the high voltage speed controller.


Function

It detects the voltage changes at the wires of brushless motor, and then outputs the RPM signal. This RPM sensor can work with some speed control systems for helicopters. And one of its typical applications is to work as the RPM sensor for V-Bar system made by Mikado.
