Stray-Load Losses in Polyphase Induction Maclines

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1959
The total stray-load loss of a polyphase induction machine of the squirrel-cage type is given by the formula: WL = WC + WE + WSL1 + WSL2 + WZ + WB + WK (13) where the several items, except Wc, are given by equations 1, 7, 6, 9, 10, and 12. The sum of WE and Wc can be determined separately from the other losses by measuring the input to the stator when ...

Stray load losses in induction motors: a challenge to academia

Power Engineering Journal, 1997
In the February 1997 issue of Power Engineering Journal, Prof. Stephen Williamson published a short article entitled `Stray losses-a residue of ignorance'. In a paper by the author published at the Lisbon Conference on 'Energy efficiency improvements in electric motors and drives' in October 1996, it was concluded that the subject of stray load losses ...

Measurement of Stray Load Loss in Polyphase Induction Motors

Transactions of the American Institute of Electrical Engineers, 1932
FOR LACK of a satisfactory method of measurement, no provision is made for stray load losses in the A.I.E.E. standard efficiency tests for induction motors. These losses may amount to from 2 to 5 per cent in squirrel cage motors from 1 to 5 hp. in size, decreasing gradually with increase in motor rating until they are less than 1 per cent for motors of

Modelling of Stray-Load Loss for Medium Power Induction Motors

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
In recent years there has been a thrust towards developing high efficiency motors for industrial applications. To design a high efficiency motor, it is necessary to develop models that can estimate the losses in the motor. One of the losses that is difficult to estimate is stray losses.

The Influence of Inverter Feeding on the Apparent Stray Inductance of Asynchronous Machines

IEEE Transactions on Industry Applications, 1983
The stray inductance is an important parameter for the design of inverters feeding asynchronous machines. Measurements are proposed which are relevant for determining the apparent stray inductance of an inverter-fed asynchronous machine. These measurements show that the apparent stray inductance is considerably smaller than the one obtained with ...

When loads stray: Evaluation of Different Measurement Methods to Determine Stray Load Losses in Induction Machines

IEEE Industrial Electronics Magazine, 2007
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

Study on the Impact of Layer Number on Stray Inductance of Busbar

Applied Mechanics and Materials, 2013
In high power converter design, low-inductance busbar connecting DC capacitors and power devices is main concern to improve the quality of the whole power electronics system. This paper analyzes the impact of layer-number on the stray inductance of busbar taking a subway traction converter as example.

Stray loss in solid-rotor induction machines

IEE Proceedings B Electric Power Applications, 1982
The 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 ...
