Abstract

PURPOSE: To simplify the structer of a coreless motor with an encoder to reduce the cost thereof by containing the interior of the motor with the encoder portion.
CONSTITUTION: An encoder slit disk 101 is fixed to the winding holding disk periphery of the rotor of a coreless motor with an encoder, and incorporates small recesses 117 and 118 for containing a photosensitive element and a light source lamp at the outer cylinder making contact with the surface thereof with light receiving photoelectric element and an LED arranged in the recesses, respectively. The light from the light source is received at the photosensitive element in the recess 117 as the reflected light via moire pattern on the disk 101 to produce a speed signal corresponding to the speed at the output. Since the encoder portion is contained in the motor as above, it can simplify the structure of the motor so as to reduce the cost thereof.
