Abstract:
The present invention increases the efficiency and torque of a rotating electrical machine using a pressed powder core by a low-cost and highly reliable method.
A radial gap-type inner rotor-type or outer rotor-type rotating electrical machine is provided with a stator having m radial winding poles, and a rotor. The stator is a polar anisotropic pressed powder core subjected to magnetic field orientation such that the m radial winding poles serve as poles and subjected to compression molding.
