Abstract

PURPOSE:To enable to withstand the condition of operation encountering high energy loss when a high speed response is performed by a method wherein a non- magnetic member, with which a magnetic member and the first coupling main body are magnetically disconnected, is provided at the aperture part on a coupling section, and a device with which cooling air will be feeded to the coupled section is provided. CONSTITUTION:The magnetic member 7, which is opposing to a magnetic pole piece 2 through the intermediary of an annular void 8 and cylindrically formed on the first coupling main body 3 through a non-magnetic member 9, is securely provided and a plurality of grooves 7a are formed in axial direction on the main shaft 1 on the inner circumferential surface of the above. Also, on the non-magnetic member 9 consisting of aluminum and the like, a plurality of ventilating holes 9a and a plurality of vanes 9b, which were arranged between the ventilating holes, are formed in a body and constitutes a ventilating device. Besides, a magnetic pole piece 2 and the non-magnetic section 9 are arranged in an annular void 8 through the intermediary of a void in radial direction, a conductive plate 10 which was cylindrically formed with a thin copper plate and the like is supported by a support 11, and the second coupling main body 12 is constituted by the conductive plate 10 and the support 11.
