INTRODUCTION:

The stepper motor is used widely in motion control systems where it is often operated in a continuous or constant speed mode rather than in a stepping mode.

A multistack variable-reluctance stepper motor is analyzed using the concept of multiple reference frames

An average-value model is developed using the concept of multiple reference frames

STEPPER MOTOR OPERATING PRINCIPLE

When the winding on a certain phase is excited (energized) the rotor will rotate, seeking alignment with the excited phase winding, such that maximizing the inductance of that phase.

This position is the stable equilibrium position of rotor where the net torque is zero.

MULTISTACK V-R STEPPER MOTOR

Multi-stack variable-reluctance motors are widely used to give smaller step sizes. The motor is divided along its axial length into magnetically isolated sections “stacks”, and each of these sections can be excited by a separate winding..

The stator of each stack consists of “N”poles and each pole has a number of teeth ”x” and carries a phase winding.

The teeth on the different stator stacks are misaligned.

The rotor stacks have number of teeth equals to stator teeth number but they are aligned

CONCLUSION:

Operation of various stepper motor is discussed.

A multistack variable-reluctance stepper motor is analyzed using the concept of multiple reference frames

The method of multiple reference frames has been Extended to provide an average-value model

This model can be used as an unique tool to aid in the design of the machine as well as in the design of the controls associated with the electronic drive system.
