Abstract
A coreless motor may include: a rotor having a magnet whose circumferential face is magnetized to multiple poles; a stator for rotatably supporting said rotor with a bearing interposed between said stator and said rotor; a coreless coil which is opposed to said circumferential face of said magnet with a space interposed between said coil and said circumferential face and which has a plurality of effective conductors that contribute to torque generation and a plurality of connection conductors that connect the adjacent effective conductors; and a support member having a coil supporting portion that supports said coreless coil; wherein said coil supporting portion supports circumferential faces of said connection conductors to position said coreless coil in the radial direction.
