How does the throttle work...

[Desertprep]

on a controller for a brushless motor with halls? Is a throttle the same thing as a potentiometer? How much voltage is used in them?

 

[Farfle]

Most hall sensor throttles are fed by 5 volts from the controller, and output around 1 to 4 volts, and use a hall sensor and a moving magnet. As the magnet moves past it from north to south, the hall sensor outputs a changing voltage based on where the magnet is.

So...where does the throttle fit in? Maybe I am not using the right term..the "grip" on the handlebar that i can twist forward to increase the speed of the bike? Is that the throttle?

The throttle is whatever device you use to control power input to the motor.

It can be a potentiometer, a switch, a hall-effect sensor/magnet, etc.

Is there some way that a computer can be used instead of the twist-throttle, i.e. can substitute for it, to send information to the controller?
