ABSTRACT:
A method of manufacturing an index apparatus includes thermally transferring a hot stamped section having a low light reflectance onto an outer peripheral surface of a magnet of a frequency generator for speed detection provided on an outer periphery of the motor. The method also includes thermally transferring a hot stamp section having a high light reflectance and a smaller width than the hot stamp section having a low light reflectance onto the hot stamp section having a low light reflectance. A position mark can be provided in the vicinity of the hot stamp section having a high light reflectance. The position mark serves for detecting a position of the hot stamp section having a high light reflectance.
