A comprehensive design procedure for low torque-ripple variable-reluctance motor drives

A procedure for designing variable-reluctance motor (VRM) drives for low torque-ripple applications. The procedure is comprehensive because it begins with the fundamental selection of pole numbers and geometry, and proceeds to final design. It provides a complete, clear and concise path to a successful design for a low torque-ripple drive. There are two important contributions of the work presented. First, the design procedure explicates the issues involved in designing VRMs for torque-ripple sensitive applications. Second, results of the motor design are amenable to simple control methods which offer acceptable performance in many applications. In the procedure outlined the VRM geometry, inverter voltages are tailored to minimize torque ripple.<>
