When using electric motors the rpm sensor signal usually consists of the (electric) field speed. In order to obtain the actual engine speed the field speed must be divided by half the number of motor poles. Using a 2-pole motor thus the measured speed corresponds to the motor speed. With a 10-pole motor on the other hand the field speed is five times higher than the actual speed. | '''Electro heli'''<br /> | ||

Also for nitro/gas engines the measured speed of the sensor may be higher than the actual speed. For example when a magnetic sensor is installed and more than one magnets are used for measuring the rotational speed, the rpm output will be multiplied by the number of magnets. So when two sensor magnets are used the rpm signal from the sensor will be twice the engine revolutions. So in order the rotor speed matches the rotor speed you set with the transmitter you must specifiy the factor by how much the incoming rpm signal must be divided to get the actual motor rpm.<br /> | Also for nitro/gas engines the measured speed of the sensor may be higher than the actual speed.

'''Telemetry'''<br /> | |||
For MICROBEAST PLUS Firmware 5.4.0 with '''Telemetry support''' this setting is also used for calculating the rotor speed that is displayed in your telemetry screen. Therefor it is not necessary to enable the GOVERNOR feature, of course you can use the internal governor of your ESC when using telemetry! Simply adjust the displayed rotor speed by changing the division factor for accounting the number of motor poles here.<br /> | For MICROBEAST PLUS Firmware 5.4.0 with '''Telemetry support''' this setting is also used for calculating the rotor speed that is displayed in your telemetry screen.
