Abstract

PURPOSE:To reduce number of parts and to shorten the axial length of an outer fan type rotor by integrally forming the center hub of a rotation brake disk and an outer van to surround the outer periphery of a detector coupled with a rotational shaft at the center of the outer fan cover. CONSTITUTION:A center hub 13b formed in the shape formed with an annular recess in the extending direction of a rotational shaft 11a is mounted at the end of the shaft 11a, a rotary brake disk 13a is supported to the outer periphery of the hub 13b, and an outer fan 12 is integrally formed. Rotary detector 5 is supported to an arm 15 formed inside the center of an outer fan cover 14, disposed on the inner peripheral recess of the hub 13b, and the rotational shaft 1a of the detector 5 is mounted at the end of the shaft 11a. Thus, the supporting members of the disk 13a and the fan 12 can be commonly used, and even if the detector 5 is provided, the axial length is not increased.

In this figure, the detector 5 is mounted and supported inside the center of the outer fan cover 14 that surrounds the outer fan 12 via an axial support arm 15, and the rotating shaft 5a is connected to the rotating shaft 11 & of the motor body 11 at the end surface. The tip is directly fitted into the insertion hole provided in the holder. A center hub 18b that supports the rotational braking disk tga of the electromagnetic brake 18 is fitted to the end of the rotating shaft 11a on the detector 5 side. It is integrally formed with the outer fan 12 surrounding the outer periphery. The outer fan 12 can also be screwed to the rotational braking disk taa support portion of the center hub 18b.
