Simulation of hybrid stepping motor using matlab-simulink

Abstract

Recently, hybrid stepping motors are being used extensively over a wide range of application especially for precise positioning. This is due to their advantages of having higher efficiency, maintain very high resolution due to the small step angle and other advantages over other types of stepping motor. Therefore this project takes for granted to study their transient performance over various situations. This project is mainly based on modelling and simulation of two phase hybrid stepping motor. The presented model is able to perform the transient performance of the motor with three types of operation; two phases on, one phase on and half stepping. The model is developed in Matlab-Simulink at first and later is presented using the Graphical User Interface (GUI) in order to change the motors parameters independently during each simulation conducted. The GUI can be also used to show various results of simulation. The model described enables calculations of motor current and voltages as well as performing the speed and position responses for the rotor during each excitation. Using this model, it is capable of performing the simulations of hybrid stepping motor with various parameters. The simulations results are presented with a detail explanation on each part of the study conducted. The results show that hybrid stepping motor can be used for precise positioning especially when small step angle are required.
