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.

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 ...

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 ...

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.

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.

Study on Influence of Stray Inductance in Micro EDM Using Electrostatic Induction Feeding Method
Key Engineering Materials, 2010In the micro EDM method by electrostatic induction feeding, a pulse generator is coupled to the tool electrode by a capacitor, since the negative influence of the stray capacitance in the circuit can be eliminated, and the discharge energy per pulse can be minimized, thereby realizing discharge craters of nanometer order.

Thermal effects of stray load losses in induction machines
Conference Record of the 1999 IEEE Industry Applications Conference. Thirty-Forth IAS Annual Meeting (Cat. No.99CH36370), 2000Additional heat produced in induction machines due to stray load losses could influence the plant rating, winding insulation design, operating limit and the machine protection design. Quantifying this additional heat and stray load losses accurately and, hence, investigating the extent of some of these influences are the concerns of this paper.

A review of condition monitoring of induction motors based on stray flux
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017The induction motors are widely used in different industry areas which can experience various kinds of faults in stators and rotors. In order to early diagnose motor faults, the classical condition monitoring method focusing on stator current spectrum is well researched and presented.

Reverse-Rotation Test for the Determination of Stray Load Loss in Induction Machines
Transactions of the American Institute of Electrical Engineers, 1939VARIOUS methods for the accurate determination of stray load loss in induction machines have been devised in recent years. Also older methods have been improved and developed as the nature of the loss has become better understood. The employment of different methods of testing on a given machine seldom shows complete agreement in results, due to minor ...
