In a coreless-brushless motor in which a driving coil block (21) is mounted on a stator yoke (11), a bearing (16) is fixed to the stator yoke in alignment with the central portion of the driving coil block, a rotary shaft (17) is rotatably supported by the bearing (16), a rotor yoke (18) is affixed to the rotary shaft (17) and a rotor magnet (19) is mounted on the rotor yoke (18) in adjacent and opposing relation to the driving coil block (21), a magnetoelectric transducer pellet (35) is housed in a recess (34) made in the stator yoke (11) on the side of the driving coil block (21), for detecting magnetic fluxes emanating from the rotor magnet (19). The magnetoelectric transducer pellet (35) is connected to wires of a flexible printed circuit sheet (36), which is disposed between the stator yoke (11) and the driving coil block (21). |
