摘要：

A system for measurement of rotational power loss is described comprising a 2-channel digital waveform generation, a 4-channel data acquisition board and gain controlled amplification circuitry. This paper also describes the theory, development and testing of a simple and accurate means of measuring localised rotational flux density which avoids the need to drill holes in samples for search coils. The results of measurements on non-oriented, grain-oriented and amorphous material are presented and the difference between the measured rotational loss for clockwise and anticlockwise rotation of the flux is discussed.
