Abstract :
A novel dual-excitation permanent magnet Vernier machine; DEPMVM, which has the feature of high torque at low speed, is presented. This machine has two stators both inside and outside of a ring shaped rotor, and its coils are wound around the yokes. These special structures are adopted as a result of detailed investigations of the machines which make use of the so-called `magnetic gearing effect´. A prototype machine of the DEPMVM is designed and fabricated, and its experimental results indicate the promising nature of the machine
