Torque maximization in high-torque density multiphase drives based on induction motors

2010 IEEE Energy Conversion Congress and Exposition, 2010
Nowadays, there is an increasing interest towards multi-phase motor drives, i.e. with a number of phases greater than three, especially for medium and high power applications such as naval and railway propulsion systems.

Segmented exterior-rotor PMSM for increased torque density

2023 13th International Electric Drives Production Conference (EDPC), 2023
Embedded permanent magnets are widely used for electrical machines with interior-rotor. This provides better protection of the magnets and enables the use of an additional reluctance torque for torque density improvements. For external rotors, the use of surface-mounted permanent magnets is common.

Torque density improvements for high performance machines

2013 International Electric Machines & Drives Conference, 2013
In this paper, the main aim is to propose and investigate possible methods for extending and improving the torque density capabilities of high performance, electrical machines. This is achieved by combining performance enhancing strategies such as the use of an outer rotor, the use of cobalt iron laminations and the adoption of high performance winding

High Torque Density Propulsion Motors

Naval Engineers Journal, 2005
The size and weight of electric drive components are primary considerations in their successful integration into various Naval platforms. Direct drive propulsion motors are of particular importance due to their requirement of developing full power at low shaft speed.

A Novel Magnetic Gear: Toward a Higher Torque Density

IEEE Transactions on Magnetics, 2015
Magnetic gears (MGs) are potential alternatives to conventional mechanical gear boxes. With high performance permanent magnets (PMs) and new topologies, today MGs are capable to transmit a torque that is competitive with mechanical gear boxes in a totally contact-free way.

An improved torque density Modulated Pole Machine for low speed high torque applications

6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012
This paper presents a new topology for three-phase Modulated Pole Machines. This new topology the “Combined Phase Modulated Pole Machine” is analysed and compared to the more traditional technology of three separate single phase units stacked axially with a separation between phases.
