Modelling of Stray-Load Loss for Medium Power Induction Motors
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018In 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.

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 Influence of Inverter Feeding on the Apparent Stray Inductance of Asynchronous Machines
IEEE Transactions on Industry Applications, 1983The 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 ...

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

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 ...

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.

Study on the Impact of Layer Number on Stray Inductance of Busbar
Applied Mechanics and Materials, 2013In 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.

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.

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.
