There are many methods for activating a stepping motor at high frequency range. The one that is often used for this kind of activating is applying high frequency pulses into the motor. Although this methods is often used, it brings lots of effects such as slipping out of a right position that we’ve expected and when the motor stop moving it causes heat in the motor’s body. This thesis for avoid those effects then sinusoidal activating is presented. In order to decrease an excitation induce voltage, then we join an encoder to the stepping motor. The 0utput of the encoder will be decoded and become sine and cosine signals. Sine cosine signals are sent to a driving motor circuit . For more convenience this thesis connected its system to a computer. Consequently we can verify system error.
