Data Processing System of Induction Motor in No-Load Test;

It also discusses the style for no-load test and short circuit test, so as to conclude the reasonable load selection for the optimum efficiency of transformer.

The cause of over standard acetylene content in a SZZ-3150/40 on-load voltage regulator is found out by chromatogram analysis and no-load test.

This article introduces a device for no-load running test of main components of drilling rig.

The study of idle power on woodworking drill press (2);

The study of idle power on woodworking drill press (3);

The relationship between the rpm of the spindle, the force exerted on the spindle by the V-belt and the idle power of a wood-working drill was studied experimentally.

Reducing no-load loss of transformer iron core on locomotive;

Effects of adopting transformer electrical steel and HIB steel on no-load loss and noise level of transformer are analyzed.

The distribution of magnetic flux density in the iron core was studied by applying a voltage,voltage waveform and frequency change while the no-load loss of transformer was being measured,and the factors having effect on the measurement of no-load loss of transformer were theoretically analysed in detail.
