磁気ギヤ装置
Document Type and Number:
Japanese Patent JP7273744
Kind Code:
B2
Abstract:
To realize a gear device having high cooling performance.SOLUTION: A magnetic geared motor 1 includes a stator 10, a low-speed rotor 20 surrounding the stator 10, and a high-speed rotor 30 surrounding the low-speed rotor 20. The stator 10 includes a plurality of teeth 11 that are arranged in a ring-like shape, and coils 12 wound around the respective teeth 11. The low-speed rotor 20 includes a plurality of magnetic pieces 21 that are arranged in a ring-like shape surrounding the stator 10, and a first support member 40 that supports the magnetic pieces 21. The high-speed rotor 30 includes a plurality of magnets 31 that are arranged in a ring-like shape surrounding the plurality of magnetic pieces 21, and a second support member 50 that supports the magnets 31. A plurality of connection holes 44 that are opposed to the coils 12 of the stator 10 are formed in the first support member 40. A plurality of opening sections 53 that are opposed to the connection holes 44 are formed in the second support member 50.SELECTED DRAWING: Figure 1
