Throttles (Hall Effect)
Hall Effect Throttles:
A hall effect throttle is a device that uses a magnetic sensor to control the speed of a motor. It works by measuring the proximity of a magnet to the sensor, and uses this information to adjust the voltage supplied to the motor. When the magnet is far away from the sensor, the output voltage is low, and as the magnet is moved closer to the sensor, the voltage increases. The range of voltage that can be generated by this device is typically between 0V and 4.6V, as the magnet has a limit distance in which can be close to the sensor. This range may be different than that of a potentiometer, but most circuits are designed to work within this range. With hall effect throttle, the speed of the motor can be adjusted by simply moving the magnet closer or farther from the sensor.
