WebJun 29, 2012 · IPM motors produce torque based on two different mechanisms. The first is permanent-magnet torque which is generated by the flux linkage between the PM rotor field and the electro-magnetic field of the stator. It is the same torque produced by SPM motors. IPM designs produce a second force known as reluctance torque. WebMar 1, 2024 · A hyperbolic form analytical expression for optimal rotor iron pole curve in IPM motors to mitigate pulsating torque components is developed and validated through FEA method and experimental tests. Interior permanent magnet (IPM) motors are of extensive interest in high-speed applications, where high efficiency, high power density and …
WebWing-type and wing-shaped spoke-type configurations were proposed to place more and more PM poles in the rotor [83, 84]. Compared to spoke-type only structure, the airgap flux density could be enhanced by 25%, as depicted in Fig. 10 (b) and (c). Slightly higher torque output was also achieved compared to the initial rare-earth IPM machine.
WebThis paper presents three methods for improving the performance of the spoke-shaped IPM magnetic gear. First, the position of the magnetic bridges is changed from the air gap side to the back yoke side to increase the effective magnetic flux. Second, amorphous alloy is used for the rotor core and pole pieces in order to reduce iron loss.
