“…On the other hand, by attaching a magnetic composite material around the conductor, a magnetic field passes through the magnetic composite material. Here, a method of attaching the magnetic composite material directly to the coil has been studied ; however, if a magnetic composite material is directly attached to the winding of the IPM, not only to the outer periphery of the winding but also to the inner area, the magnetic composite material will flow into it. As a result, a leakage magnetic flux flows through the magnetic composite material and into the winding wire causing interlinkage with the winding, which leads to an increase in the AC resistance.…”

“…For the measurement of the complex permeability, an impedance analyzer (16454A) and a terminal adapter (42942A) were used to measure the magnetic material as a toroidal core . Complex magnetic permeability is composed of the real part of the magnetic composite material μ ′ = 19.5 and the complex permeability imaginary part μ″ = 0.25.…”

The demand for highly efficient motors has risen because of the increase in the number of hybrid electrical vehicles and electrical vehicles. Eddy current loss in the motors, which is generated by leakage of magnetic flux interlinked with the winding, is one factor that leads to the decrease in efficiency. Therefore, in this paper, by attaching magnetic composite materials to the winding of the interior permanent magnet (IPM) motor, we attempted to reduce the eddy current loss due to the leakage of magnetic flux of the rotor while maintaining the torque. © 2020 Institute of Electrical Engineers of Japan.
