Radial magnetic multipole

The radial magnetic flux density multipole surface developed by our company, has better performance than the traditional tile shaped magnetic steel assembly, magnetic circuit design and the design of magnetic radiation ring are completely different. The radiation ring surface magnetic field distribution of a saddle shape multipole magnetic surface magnetic field distribution developed by our company is the sine wave, more conducive to the design of the motor.
