Abstract
The utility model discloses an iron core structure used for a motor comprises a stator and a rotor. The rotor is constituted by a central ring and an outer ring. An inner wall of the central ring is provided with a groove, and the surface of the outer ring is smooth, and one side edge is provided with an eave. At least three supporting shafts are disposed between the central ring and the outer ring, and one side surface of each of the supporting shafts is provided with a screwed hole. An annular ring is disposed between the inner ring and the outer ring. An opening of a stator air gap faces outwards, and a thickness of the annular-shaped structure of the bottom part does not exceed 3cm. The stator is disposed on the outer part of the rotor in a sleeved manner, and the rotor and the stator are in an interference fit.
Description
Technical field
The utility model relates to a kind of electric machine iron core, relates in particular to a kind of iron core that is applied to the motor of electric bicycle.
Background technology
Along with the current existing electric bicycle motor of technological progress is constantly towards little, the high-power direction progress of volume, yet limited space in motor wheel hub causes each piece volumes in motor constantly to reduce, and causes being difficult for installing.
Utility model content
The purpose of this utility model is to provide a kind of core for dynamo structure, the draw-in groove of centering ring inwall, and the groove at the support column back side etc. is designed with the installation that helps motor internal part, reasonable arrangement space, effectively compression motor volume.
The utility model is the core for dynamo structure that its technical problem of solution proposes, comprise stator, rotor, it is characterized in that: rotor is comprised of centering ring and outer shroud, centering ring inwall is provided with groove one, being convenient to mandrel installs, outer shroud smooth surface, one lateral edges is provided with cornice, is convenient to stator and fixes; 3 back shafts are at least set between centering ring and outer shroud, and its further technical scheme is that 5 back shafts are set between centering ring and outer shroud; Back shaft one side surface is provided with a screwed hole; Between interior ring and outer shroud, be provided with an annular ring;
Stator air gap opening part is outside, and its base circle structural thickness is no more than 3cm; Stator sleeve is connected to rotor exterior, and is interference fit between rotor.
Annular ring is divided into two-layer, and wherein one deck is wider, is connected with back shaft, and another layer is narrower, and its top is provided with draw-in groove, is convenient to install.
The screwed hole on back shaft surface is arranged in circle, is convenient to installing component, makes it stressed even in active procedure.
Back shaft is comprised of two rectangular strip structures, and two list structure junctions are rectangular, effectively strengthen its intensity.
The side that back shaft is not established screwed hole is provided with a depression, is convenient to rotor and installs.
The utility model has the advantage of, the groove of stator center ring is convenient to install mandrel, and the screwed hole on stator support axle is convenient to install miscellaneous part, is not only convenient to install, and can effectively improves space availability ratio, reduces motor volume.
