Abstract: A power transmission device includes a magnetic gear with an input shaft magnet that receives rotational driving force, a magnetic modulator to modulate magnetic flux, a multi-pole magnet with more poles than the input shaft magnet, and an output shaft rotating with either the magnetic modulator or the multi-pole magnet. The device also features a magnetic circuit where the magnetic flux flows in parallel from the input shaft magnet. Between the input shaft magnet and the magnetic modulator is a flux-forming member with higher magnetic permeability than a vacuum, forming a short-circuiting flux path. The magnetic circuit creates two paths: a torque generation path, where magnetic flux flows through the magnetic modulator and multi-pole magnet, and a short-circuit flux path, where it bypasses the magnetic modulator. The flux-forming member's magnetic permeability is within ±20% of the value that maximizes torque.
