Abstract
An improved method of measuring rotational power loss in electrical steels has been developed. The technique is based on the use of apparatus in which signals from orthogonal B and H coils are processed electronically to derive the rotational power loss in a single sample of electrical steel magnetized under known conditions. The wattmeter operates over a frequency range from 20 to 1000 Hz and can be used to quickly measure rotational loss in non-oriented or grain-oriented electrical steel to an accuracy better than ±2%, a considerable improvement over existing thermocouple techniques. The paper describes the instrument and its capabilities before presenting a series of rotational loss measurements obtained on a series of nonoriented electrical steels.
