Abstract
This paper presents a new low-cost, hybrid SR motor intended for use in adjustable-speed pump drive systems. This motor is a single-phase motor, driven by a unipolar converter. This motor uses both the reluctance torque and the permanent magnet interaction torque. Compared with normal single-phase SR motors, it has an increased torque density. The cogging torque is properly used in this motor for reducing the torque ripple. It is demonstrated that such a motor drive system can be a suitable candidate to advantageously compete with the existing motor drive systems for low-cost applications. Finite element models are used to analyze and predict the motor's performance. The proposed motor drive system has been fabricated and its performance tested in the laboratory. These experimental results are also presentedKeywords
