  1. Based on many references form civil and abroad, the author mainly studies the measurment theory and method for flux, raising height, axial power and rotational velocity. avoiding many complicated and intermediate courses for power wastage analysis, introduces the electric measurement and using efficiency curve of motor in measureing axial power, and satisfies the automatization of the device. the paper also provides a new method, inductive winding, in measuring rotational velocity of electromotor, supplys limitations of other method in measuring rotational velocity of electromotor in water, and meet practical needs in developing diving electric pump for corporation
