Produktbeschreibung
This book explains the method to control the three basic things of an induction motor. 1.Switching 2.Direction of rotation 3.speed. This book explains the simple ways to control the direction of the motor and switching of the motor. By switching i mean the on off state of the motor. To control the spped of the motor i have used cycloconverter. The advantage of cycloconverter of using cycloconverter is that on low speed the torque of the motor is maintained while using other methods we face a problem that on low speed the torque of the motor is reduced which is a major cause of wastage of electricity. Cycloconerter is direction conversion method means that it has no intermediate stage while changing the supply frequency given to the motor. Which shows that it power is maintained even at low speed.In most of the cases while changing the frequency we change the frequency first we converter AC into DC and then back to AC to change the frequency while in cyclonverter there is direction conversion, no intermediate state which is good for both power and torque of the motor.
