Magnetically Geared Induction Machines [PDF]
IEEE Transactions on Magnetics, 2015 A wound-rotor induction machine is artfully coupled to a magnetic gear to achieve a high-torque-density drive system called magnetically geared induction machine (MaGIM). The high-speed rotor of MaGIM is common to both the machine and gear sides. A rotating diode rectifier electrically links the machine's wound rotor and a dc boost winding on the gear ...

A New Structure for the Magnetic Gear [PDF]
IEEE Access, 2019 In this paper, a new structure for increasing the magnetic gear torque is proposed, which has high torque density and high mechanical properties. The permanent magnets (PMs) of the outer rotor are spoked and magnetized along the tangential direction. The PMs of inner rotor are the surface-mount type and magnetized in the radial direction.

Rotary-to-Linear Magnetic Gear
IEEE Transactions on Industry Applications, 2023 The paper introduces a permanent magnet rotary-to-linear magnetic gear whose topology is derived based on the operating principle of a transverse flux VRPM machine. It is shown that when the number of poles per unit length on all three members, rotor, translator and stationary flux modulating ferromagnetic pieces, are the same, the proposed gear is ...
