Abstract
PurposeThe aim of this paper is to analyse the influence of various methods of controlling a stepper linear reluctance motor on the dynamic parameters of this motor.Design/methodology/approachConstruction, principle of working, and mathematical model of a four‐band stepper linear reluctance motor are shortly discussed. In order to elaborate an effective tool for motor performance analysis, a circuital approach was applied. To increase model accuracy, major parameters of the model (main self‐ and leakage inductances) were calculated on the basis of a 3D electromagnetic field distribution using Finite Element Method (FEM). The nonlinearity of the core was taken into account. Elaborated mathematical model was implemented in MatLab‐Simulink environment. Selected results of investigations are presented.FindingsThe elaborated mathematical model and the review of control methods are very useful for analysis of dynamic operation of stepper linear reluctance motors.Originality/valueThe paper provides a review of control methods of stepper linear reluctance motors.
