Zusammenfassung:	PROBLEM TO BE SOLVED: To prolong the life time of a durability tester itself by using a driving machine, having a small radius of rotor and a long total use time and durable to high-speed rotation, in the high-speed up-down durability tester. SOLUTION: In the high-speed up-down durability tester, a body T to be tested that is supported by a support bracket B integrated with a base V and a drive shaft 2 of the driving machine M, installed on the driving base V, concentrically with an input shaft 1 of the body T to be tested, are connected via couplings 5, 6, 8, and the rotational speed of the driving machine M is made change up and down at a high-speed, to confirm the fatigue strength of the body T to be tested. The driving machine M is constituted by a permanent magnet type synchronous motor. COPYRIGHT: (C)2007,JPO&INPIT
