Squirrel Cage Rotor Design and Manufacturing for High-Speed Applications
(IEEE, 2018-11-07)
A high-speed squirrel-cage induction machine requires totally different design compared to the traditional squirrel cage industrial motor because of mechanical limitations caused by the high speed. This results in a more ...
Influence of Travelling Current Linkage Harmonics on Inductance Variation, Torque Ripple and Sensorless Capability of Tooth-Coil Permanent-Magnet Synchronous Machines
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
This paper introduces an important source of torque ripple in PMSMs with tooth-coil windings (TC-PMSMs). It is theoretically proven that saturation and cross-saturation phenomena caused by the non-synchronous harmonics of ...
Motion Synchronization of Biaxial Linear Tooth Belt Drive System
