Design of a High-Speed Solid-Rotor Induction Machine With an Asymmetric Winding and Suppression of the Current Unbalance by Special Coil Arrangements

IEEE Access, 2019
High-speed solid-rotor induction machines (IMs) suffer from higher rotor eddy-current losses (as a result of the air-gap flux density harmonics) more than any other type of high-speed machines because of the solid-rotor steel.

Five-Phase Modular External Rotor PM Machines with Different Rotor Poles: A Comparative Simulation Study

Modelling and Simulation in Engineering, 2012
The performance of fault-tolerant modular permanent magnet machines depends on the proper selection of the pole and slot numbers which result in negligible coupling between phases.

Asymmetrically Chorded Multi-Layer Winding and Slot Design for Suppressing Space Harmonic Effects in Induction Motors

IEEE Access
In previous studies, the first method to eliminate unwanted space harmonic effects in asynchronous motors is chording. However, it is possible to make winding changes in a way that can target a single harmonic within chording and only covers a certain ...

Electromagnetic Vibration Analysis and Mitigation of FSCW PM Machines with Auxiliary Teeth

Machines
Auxiliary teeth are usually used in fractional-slot concentrated winding (FSCW) machines for fault tolerance. However, the influence of auxiliary teeth on torque and electromagnetic vibration performance differs with different slot–pole configurations ...

Diagnosis of induction motor stator faults around rotor slot harmonics using the Matrix Pencil method

Results in Engineering
To improve the monitoring and diagnosis of stator faults at their early stages in induction motors, several methods have been developed, particularly parametric methods. This article thus proposes a new approach based on the Matrix Pencil method for high-resolution spectral analysis.
