摘要

A single phase equivalent circuit and its parameters for a 9-phase hybrid stepping motor are derived, which is based on the structural properties and the stepping motor mathematical model. The motor power/angle characteristics can be obtained from the circuit representation of the stepping motor and the synchronous machine theory. According to the requirements for the pull-out torque/speed characteristics, frequency/voltage coordinating control strategy for the stepping motor driving system is proposed. The realization of this new control strategy and its application to a 9-phase hybrid stepping motor drive system are described and discussed. Experimental results show the feasibility of the proposed stepping motor driving system design method.
