Stray loss in solid-rotor induction machines
IEE Proceedings B Electric Power Applications, 1982The paper presents measurements and calculations of the stray loss in several solid-rotor versions of British Rail's tubular-axle induction motor (TAIM) of 150 kW capacity. The use of a large airgap and of narrow slot openings as means of reducing the loss to manageable levels are investigated, and it is found that the large gap approach is more ...

The efficiency data provided by manufacturers are measured or calculated according to different national and international standards. These standards use different means to incorporate the stray load losses; thus the efficiency values obtained from different testing standards can differ by several percent. This leads to problems in competition and to a

An investigation of stray loss in induction motors.
1963An investigation of induction motor stray loss has been carried out by the Rawcliffe and Menon Test, and by a test using the experimental and designer's equivalent circuits. Refinements have been made in the former test, and much effort has been spent in measuring mechanical torque accurately.

Influence of the sinusoidal supply frequency on the induction motor stray load losses
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012This papers deals with the influence of the supply frequency on the induction motor stray load losses. Due to the complexity of the stray load losses computation, a fully experimental approach has been chosen. Following the International Standard IEEE 112 method B, the additional losses have been determined in the supply frequency range of 30 Hz up to ...

Effect of stray inductance on capacitive-voltage divider
Journal of Applied Physics, 1986The effect of stray circuit inductance on the response of a capacitive-voltage divider to fast-rising voltage pulses is investigated. Results obtained from the analysis of the capacitive divider’s equivalent circuit indicate an upper-frequency limit of only 1% of the natural frequency of the circuit.

A novel method for reduction of stray loss in induction motor
2013 IEEE Power and Energy Conference at Illinois (PECI), 2013As per IEC-60034-2-1, 2007, for a rotating electrical machine, the stray loss component increases with the decrease in the size of the machine. This causes a drastic reduction in the machine efficiency, especially in small a.c. motors. Using measures for reducing stray loss will greatly help in improving the efficiency of motors.

Measurement of induction motor stray loss.
1964A dynamometer for the accurate, automatic determination of induction motor torque-speed characteristics has been developed as part of an investigation into induction motor losses. The speed range of interest is scanned at constant acceleration so as to simplify corrections for inertia torque, the speed being measured by a highly accurate tachogenerator.

Induction motor stray losses and inter-bar currents
2008 18th International Conference on Electrical Machines, 2008This paper presents measured bar-to-lamination contact resistance values for eight, 10 hp cast copper induction motors. The contact resistance values are compared to full load stray loss values determined using the IEEE input-output method. The stray losses generally decrease with decreasing contact resistance.

Stray inductance estimation with detailed model of the IGBT module
2013 15th European Conference on Power Electronics and Applications (EPE), 2013Stray inductances cause various problems in a power inverter and should be appraised and minimized at an early design stage to avoid later required countermeasures and redesign after the device prototype has been built. The stray inductances of the commutation loops of an Active Neutral Point Clamped (ANPC) inverter are estimated in this paper ...
