Study on properties of multipole switched reluctance motor designed for multichannel operation – single channel operation analysis

The following paper deals with the multipole design of the switched reluctance motor (SRM). The design is intended to facilitate the four-channel operation of the motor. Due to multipole design of the rotor and multichannel operation abilities, there are numerous potential configurations for powering the poles in each phase. Analysis of a selection of such configurations was carried out, including multichannel (MC) operating conditions (e.g., single-channel operation (SCO)). A mathematical model of three-phase MC SRM is also presented. The static electromagnetic torque characteristics were obtained together with the self-and mutual inductance characteristics. Selected laboratory test results are likewise presented in the paper.
