Abstract
PURPOSE: To facilitate ready assembling and alignment of a video head motor by inserting a cylindrical member having a slit on the wheel end surface at the end of a rotary shaft into recess slot of a holder having a light emission element and a photodetector disposed oppositely to thereby detect the rotating angle.
CONSTITUTION: A stator 1 and pneumatic bearings 16, 17 are integrated by a frame 4, a rotor permanent magnet 6 engaged with a rotary shaft 5 is installed in the frame 4, a head drum 7 is at one end of the shaft 7, and a wheel 18 is provided at the other end of the shaft 7. A cylindrical member 18 is coaxially provided with the rotary shaft 5 at the end of the wheel 18 and with a slit 18b. A holder 19 having a light emission element 20a and a photodetector 20b are disposed oppositely is inserted into the annular recess slot oppositely to the member 18a to thereby detect the angle and speed of the rotor. Thus, it can readily execute the fine adjustment of an angle detector 21 as well as disassembly and assembly of the video head motor.
