Rotor Slot Permeance Harmonics under Distorted Air-Gap Flux Waveform for Cage Induction Motors
The air-gap flux waveform for a cage induction machine is not sinusoidal in shape and contains various harmonics, including the phase-belt harmonics, slot magnetomotive force (mmf) harmonics, slot permeance harmonics, and ...
Commissioning of a High Speed Composite Rotor with Hydrostatic Dampers and Ceramic Rolling Element Bearings
(American Society of Mechanical Engineers, 1993-09)
A high speed (25,000 rpm) rotating machine with a 300 lb rotor was designed and manufactured. To accommodate the high shaft speed, 2.6 million DN, rolling element bearings were used with ceramic balls and inner races. In ...
Advanced Compulsator Technology
Compulsator selection issues are addressed, including two poles vs. four poles, shell vs. conventional rotors, relation between pulse shape and energy density, and would compensation. Electrothermal guns require a current ...
Development of Preloading and Precooling Systems for a Single-Turn Ignition Tokamak
(American Nuclear Society, 1991-05)
A basic requisite of the Fusion Ignition Experiment (IGNITEX)1 is the production of a high (20 T) toroidal field (TF) by a single turn coil. The proposed high-field technology uses precooling and preloading systems. The ...
Compulsators: Principles and Applications
The authors discuss work being done on reducing and tailoring generator internal impedances in order to maximise their transient response. The work is taking place at the centre for Electromechanics at The University of ...
