In an induction motor if air-gap is increased
WebAny reduction in the supply frequency, without a change in the terminal voltage, causes an increase in the air-gap flux. Induction motors are designed to operate at the knee point of the magnetization characteristic to make full use of the magnetic material. Therefore, the increase in flux will saturate the motor. WebThe most remarkable effect of the air-gap increment is the more required magnetizing current (i.e. smaller magnetization inductance). Note that the magnetizing current does …
