Title:
MAGNETIC GEARED MOTOR AND MANUFACTURING METHOD OF MAGNETIC GEARED MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/080110
Kind Code:
A1
Abstract:
Magnetic geared motors are expensive because a large amount of permanent magnets are used in both a high-speed rotor and a low-speed rotor. In addition, magnetic geared motors cannot be started unless the phase of a rotor and the rotating magnetic field of a stator are synchronized, and thus have the problem of requiring a starting circuit such as an inverter. Therefore, according to the present invention, coils (331, 332) are wound on a stator (3) of this magnetic geared motor and a single-phase AC power supply (9) or a DC power supply (10) is connected to the coils (331, 332), and thus the magnetic geared motor can be started by directly inputting voltage and current without using an inverter or the like, the number of permanent magnets can be reduced, and the cost of the motor can be reduced.
