Induction Motor to Stepper Motor

[Ana Mido]

Can induction motor be used as a stepper motor ?

 

[anorlunda]

Probably not. Stepper motors have special physical construction features that induction motors lack. For example, in this Wikipedia animation, the features that look like gear teeth.

[Rive]

No.

Stepper motors are special synchronous motors. Induction motors are asynchronous by nature: the slip is, what generates the torque.

If you try to use it in synchronous mode then no slip - no torque.

 

[Windadct]

Also - zero speed - essentially zero torque. If this was in any way possible ti would have been done as Steppers are expensive. However - depending on the application a BLDC/PMAC motor is often used as a servo motor... in some application a stepper or BLDC can be considered.

If you have an application that can use an induction motor, then the Stepper was probably not the best original choice.
