REALISATION OF A SPEED ADJUSTMENT SYSTEM FOR SMALL THREE PHASE SQUARREL CAGE ASYNCHRONOUS MOTORS

Öz

With the quick development of technology, the reliability of power electronic
devices has increased and costs have been significantly reduced. Depending on that,
semiconductor based power electronics circuits have spread. Induction motors are very
common all over the world and this motor has attractive in many applications due to
robust and maintainless. But squarely motor has constant speed only can be changed by
variable frequency in easy way. Sine based switching is a way to reduce harmonics
signals in power control strategy. In this study, unique DSP based solid programmed
microcontroller has been investigated to control small-power asynchronous motor
(1.1kW).
