More efficient cooling systems are an enabler for the increase in power density in an electric
traction motor. Contemplating to existing reviews, this article presents a comprehensive …

Oil-filled motors (OFMs) are widely used in deep-sea exploration and oil well extraction.
During motor operation, the rotor stirs the oil in the air gap, causing viscous loss. Viscous …

Abstract A Switched Reluctance Motor is designed for an electric auto rickshaw operating at
25 kmph. Different stator-rotor teeth combinations are worked out and the suitable …

A supercritical CO2 (S-CO2) Brayton cycle is a compact and simple power conversion
system with competitive efficiency. However, the strong real gas effects of S-CO2 pose …

Varieties of loss should be optimized to be as little as possible for the stability of the
permanent magnet in a high-speed magnetic levitated permanent magnet synchronous …

To improve the prediction accuracy of skin friction coefficient C f related shaft-type windage
loss in generators of turbine-alternator-compressor (TAC) units, an original model is …

To investigate the effects of surface roughness on windage loss and flow characteristics in a
shaft-type gap, the skin friction coefficient (C f) and flow versus Reynolds number (Re) at …

To accurately predict shaft-type and disk-type windage losses in gaps of supercritical CO 2
(sCO 2) turbine-alternator-compressor (TAC) units, the factors influencing skin friction …

This paper presents a comprehensive design and analysis of a high-speed, multi-lane,,,
slotless generator system tailored for hybrid-electric aircraft. The armature of this generator …

Windage is the effect of aerodynamic drag on the surfaces of a rotating system due to fluid
shear effects. The fluid-friction losses that occur on the rotor of rotating machines often …
