Abstract

Hysteresis motors are exciter-less and brushless machines with outstanding characteristics such as constant torque and speed, robust structure, low and constant starting current and smooth operation. On the contrary, hysteresis machines have some usage limitations such as low power factor, efficiency and torque density. In this paper, calculation of electrical EQUIVALENT CIRCUIT parameters versus design parameters of high frequency disk-type HYSTERESIS MOTORs are presented in details for steady state operating conditions. It is demonstrated that some of the EQUIVALENT CIRCUIT parameters alter significantly with input voltage and different operating conditions. Therefore, an EQUIVALENT CIRCUIT with fixed elements may give an inaccurate prediction of steady state performance of a machine in many circumstances. Furthermore, in this paper for a disk-type HYSTERESIS MOTOR which is designed and manufactured by use of variable parameter model, a SENSITIVITY ANALYSIS is presented and influences of some design parameters on machine performances are discussed. Many experiences show that W10, tr, g, Ro, Ri ( respectively, Opening of stator slot, Thickness of rotor disk, Axial air gap between stator and rotor, Outer radius of rotor and stator, Inner radius of rotor and stator) are the most important structural and effective design parameters of the disk TYPE hysteresis machines. Because of special applications of these machines and existing limitations, values of g, Ro, Ri are supposed constant concerning the initial design, and performance of the machine including the efficiency is studied when two other parameters vary. By an optimization program, optimum values of W10 and tr as two important design parameters are calculated. Based on these parameters and by their values other operation parameters such as efficiency and power factor are calculated.
