Design and Analysis of Outer-Rotor PM Motor with Segmented Rotor-Shape for Utilizing Reluctance Torque
Sakurai S., Yoshida Y., Tajima K.

<p> Recently, the market scale of a drone has grown significantly. To utilize a drone more, the operating time needs to be extended. So, a drone motor should be lightweight and high power. However, the almost drone motor has a Surface permanent magnet, and improving torque is difficult because the outer-rotor has a low-degree design. Increasing torque, the Segment PM is adapted to the drone motor. It can use a reluctance torque with an outer-rotor type. However, the ratio of the reluctance torque is low and it is not enough from a result of the previous paper. So, improvement of the reluctance torque is desired. This paper presents a novel drone motor applied to Segment PM and investigated a ratio of reluctance torque by finite element method (FEM).</p>
