Drive of a high torque, low speed switched reluctance machine

A version of a motor belonging to the class of rolling rotor motors is described. An efficient power converter for controlling the freewheeling energy in its rotor coils, requiring only a low number of switches, is also presented. Tests on an experimental model are compared with theoretical calculations. Attention is drawn to the motor's robustness and simplicity, so that it can be considered for low cost applications where large torque and low speed are required from a gearless construction.<
