磁気誘導形トルク計

抄録

Generally speaking, there are two major kinds of dynamometers, one is called absorption dynamometer and the others are tortion bar dynamometers. The magnetic induction type torquemeter developed here falls under the classification of the latter, operating on a magnetic induction method to measure a torque from a tortion angle of the rotating shaft. While the conventional torquemeters of this sort have the slip rings, this new meters have no such a device, so that can be used for high speed machines with high accuracy and simple maintenance. In this paper, their principle, design practice, material selection, besides there calibration, and experimental results are described.
