  • Abstract In the study, a new design of synchronous permanent magnet dynamotor (SPMD) with comb magnetic resistance route (CMR) structure was proposed to enhance the efficiency of generator by changing the magnetic route structure. The CMR structure was inducted the change in magnetic flux and dispersed into the staggered NS poles to affect the inner windings and led to stable sinusoidal back EMF. The main design was gone through changing the distance between the soft, width, and thickness, and numbers of poles in the CMR structure to change the magnetic field. The Taguchi method was used to make the parameter design and regression analysis. The power generation voltage was studied under different circumstances by using ANSYS MAXWELL electromagnetic simulation. The open-circuit voltage of the entity generating device was 100 mV and the voltage of simulation was 148.75 mV under 160 rpm. It verified the correctness of the simulation. The results show that the open-circuit voltage of this new SPMD with the CMR structure width at 3.65 mm, the thickness at 3.5 mm, the radius of notch at 3 mm, 28 poles, and cast iron as the soft material was 67.88 V. With a load of 100 ohms, the maximum voltage was 42.9 V and the power was 18.45 W. The new SPMD has more stable waveform, higher power generation and performance at the same speed.
