Characteristics Analysis of Novel Outer Rotor Fan-type PMSM for Increasing Power Density
Journal of Magnetics, Volume 23, Number 2, 30 Jun 2018, Pages 247-252
Abstract
Most studies on non-rare-earth motors focus on the inner-rotor-type motors, and little research has been conducted on the outer-rotor-type motors. This paper suggests a novel outer rotor fan-type permanent magnet synchronous motor (PMSM) as a non-rare earth outer rotor motor. To verify the superiority of the efficiency and output power, the novel outer rotor fan-type PMSM is compared with the surface permanent magnet synchronous motor (SPMSM), which is primarily used as an outer-rotor-type motor. The detailed design and characteristics of the outer rotor fan-type PMSM was also studied. Finally, the output characteristics of the outer rotor fan-type PMSM were verified through prototyping.
