Beschreibung
Zusammenfassung:[Object] To reduce the amount of a rare earth element used in a magnet-embedded reluctance motor without lowering the performance thereof.[Solution] A geared motor includes a synchronous reluctance motor whose maximum rotational speed is 20000 rpm to 45000 rpm and in which rare earth bonded magnets are embedded in a rotor, and a speed reducer which reduces the rotational speed of the synchronous reluctance motor to a rotational speed in a usage range while increasing torque to a predetermined range. When a radius of the rotor is represented by R (cm) and a length of the rotor in an axial direction is represented by L (cm), the rotor has a size which satisfies conditions of 2 cm ≤ R ≤ 6 cm and 2 cm ≤ L ≤ 25 cm.
