Abstract
In a coreless-brushless motor in which a driving coil block is mounted on a stator yoke, a bearing is fixed to the stator yoke in alignment with the central portion of the driving coil block, a rotary shaft is rotatably supported by the bearing, a rotor yoke is affixed to the rotary shaft and a rotor magnet is mounted on the rotor yoke in adjacent and opposing relation to the driving coil block, a magnetoelectric transducer pellet is housed in a recess made in the stator yoke on the side of the driving coil block, for detecting magnetic fluxes emanating from the rotor magnet. The magnetoelectric transducer pellet is connected to wires of a flexible printed circuit sheet, which is disposed between the stator yoke and the driving coil block.
