<p>PURPOSE:To elevate the measuring accuracy, by arranging a sensor for measuring the positions and an arithmetic unit which calculates the magnetic center of a stator based on the position of the mobile body measured with the sensor. CONSTITUTION:Sensors 15 are positioned in the directions X and Y with respect to the circumferential surface of a mobile body 10. The detection signals as outputted as analog signal with the magnitude corresponding to the desired measuring distance from the sensors 15 are amplified with an amplifier 16 and then, inputted into a computing means 17 to calculate the magnetic center of a stator 1. In this case, the computing means 17 determine the maximum and minimum of detection signals from the sensors 15 with a peak holding circuit 18. Then, the results of the measurement with the holding of peaks are averaged by a computation thereby enabling the measurement of the magnetic center at a high accuracy in a short time.</p> |
