inductive winding वाक्य

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
