Abstract: A motor-operated valve includes a motor, valve seat, valve body, magnetic gear, and controller. The motor generates rotational force when powered, allowing the valve body to open and close the valve port, which permits fluid passage. The magnetic gear transmits this force from the motor to the valve body. The controller regulates the electric current supplied to the motor. During fully-closed operation, the controller limits the current to less than a fully-closed current limit value, ensuring the valve port is completely closed. This limit value is higher than the adjusting current value, which is the current supplied during valve opening adjustments.

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.
