Internally, the mechanism of a servo motor uses a potentiometer attached to the rotating shaft to sense the position. It measures the width of the incoming pulse and applies current to the motor to turn the shaft, until the potentiometer indicates that the position corresponds to the incoming pulse width. This is a form of feedback control. The motor has received the desired position from the pulse width, and the actual shaft position is fed back to the circuit via the potentiometer.

Mar 29, 2019 · Ward-Leonard System: This Ward –leonard system is used where very sensitive speed control of the motor is required (e.g electric excavators, elevators, etc.). The arrangement of this system is as required in the figure shown below. M2 is the motor, it controls the speed of the generator. M1 may be any AC motor or DC motor with constant speed. Apr 21, 2008 · A true rheostat is a voltage control device and can be used to control the speed of a DC motor, but not an AC motor. There are special AC motors that are adaptable to speed control, and you may have one. The speed control is an SCR device similar to a wall dimmer, though the common $6 dimmer will not work. Electronic speed control of 3 phase ones is done by synthesizing an AC waveform at a custom line frequency, but your motor doesn't support that. You will probably need to replace it with a different motor type or add mechanical reduction (it looks like it's probably a 1725 RPM motor with 50x reduction already).

Basic wiring for motor control – Technical data The example code will control both kinds of motors. See the unipolar and bipolar motor schematics for information on how to wire up your motor. In this example, a potentiometer (or other sensor) on analog input 0 is used to control the movement of a stepper motor using the Arduino Stepper Library .Using a potentiometer or rheostat to control motor speed is inefficient, since substantial amounts of power are dissipated by the rheostat in the form of heat. An alternative device to control power to the motor in an AC circuit is a household dimmer switch. Currently at a resistance of 0 kOhms the motor runs at full speed, as it should do and this is how it reacts with the analogue potentiometer. At a resistance of 100 kOhms, the motor (in this case a computer fan) still has enough juice to spin, until I stop it with my finger, but then it doesn't spin without a little push.
