Influence of sleeve thickness and various structures on ...
A surface-mounted PMSM was tested, whose rotor magnetic field is excited by the PM (N33SH). Also, the remanence (Br) and coercivity (H c) are 1.1 T and 838 kA/m, respectively, in addition, the working temperature is 150°C, and the conductivity is 6.25 × 10 5 S/m.To reduce the eddy current loss in the rotor, the PMs are divided into three segments in the axial direction.
