▎ 摘  要

NOVELTY - The motor has a rotor provided with a rotor iron core (1), a graphene guide strip (2) and an end ring (3). The rotor iron core is composed of silicon steel stamped steel. The rotor iron core is provided with a guide strip groove (4) passing through two ends. The graphene guide strip is circumferentially pre-inserted in the guide strip groove. The end ring is cast and formed at two ends of the rotor iron core. The end ring is melt connected with the graphene guide strip, where length of the graphene guide strip is greater than length of the rotor iron core. Two ends of the graphene guide strip are provided with an extension section extending out of the rotor iron core. USE - Graphene guide mouse cage type three-phase asynchronous motor. ADVANTAGE - The graphene guide strip does not need to perform centrifugal casting or pressure casting aluminum, and only needs to cast the outlet end ring when processing the rotor, so as to reduce the casting difficulty and casting cost, improve the casting process. The graphene guide strip and the end ring are connected firmly, which is stable and comprehensive, and can form the short circuit ring with stable quality, thus improving the stability of the motor operation. The conductivity of the graphene conducting strip is 5-20% higher than the traditional aluminum alloy conducting strip, which greatly reduces the loss of squirrel-cage rotor when working, reduces motor heating, improves the motor efficiency or increases the output power of motor. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene guide mouse cage-type three-phase asynchronous motor. 1Rotor iron core 2Graphene guide strip 3End ring 11Guide strip groove 21Epitaxial segment
