To provide a coreless motor design device and method capable of calculating a magnetic flux density distribution and an induced voltage distribution close to an actual coreless motor.
The design device of a coreless motor having a rotor magnet and an electromagnetic coil includes a magnetic flux density calculation part for calculating a magnetic flux density distribution received from the rotor magnet performing no-load rotation, a coil wiring position calculation part for calculating the position of a single line between coil 1 windings of the electromagnetic coil, and an induced voltage calculation part for calculating an induced voltage that occurs in the single line by using the magnetic flux density distribution and the arrangement of the single line, and calculating an induced voltage distribution on an electrical angle by a set of induced voltages that occur in the single line.
