摘要
Synchronous reluctance machine with simple salient rotor are known to have poor power factor because they have a low effective reactance ratio. This paper used a 3-phase auxiliary winding and balanced capacitance compensation to influence the effective reactance ratio of a synchronous reluctance machine with simple salient rotor structure, such that its power factor and torque/ampere performance is improved. A mathematical model and dq equivalent circuit suitable for dynamic and steady state analysis was developed and used to study the synchronous operation of this machine. Analytical as well as experimental results for a 4-pole, 36 slots simple salient rotor reluctance machine showed that the effective reactance ratio increased with the capacitance size, and the machine operated at a maximum power factor of 0.969 without altering the geometry of the rotor. The torque per ampere of the machine also improved with the size of capacitor attached to the auxiliary winding. Copyright (C) 2010 Praise Worthy Prize S.r.l. - All rights reserved.
