Description

A kind of outer-rotor permanent magnet motor
Technical field
The utility model relates to technical field of motors, particularly relates to a kind of outer-rotor permanent magnet motor.
Background technology
In the large-scale permanent magnet generator of prior art, generator mainly contains inner rotor core and outer-rotor structure, the generator of outer-rotor structure is generally all provided with two bearings and supports, and two bearings bear axial force and radial load respectively, not only cost compare is high for the motor of this structure, and because be provided with two bearings, so the concentric problem of two bearings must be ensured when installing, install cumbersome.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of cost lower and install outer-rotor permanent magnet motor eaily.
The technical scheme that the utility model adopts is: a kind of outer-rotor permanent magnet motor, it comprises stator, rotor, permanent magnet, stator support and bearing, described stator is connected by hot jacket interference fit with stator support, it also comprises bearing outside, bearing plate and bearing supports, described rotor is cup-shaped rotor, described cup-shaped rotor inner ring is provided with permanent magnet, and leave gap between described permanent magnet and stator, described cup-shaped rotor bottom, outer ring and the bearing outside of bearing are fixedly connected with by securing member, the inner ring of described bearing is connected by hot jacket interference fit with bearing supports one end, described bearing supports one end is fixedly connected with by securing member with bearing cover, and the described bearing supports other end is fixedly connected with by securing member with stator support.
Adopt above structure compared with prior art, the utility model has the following advantages: adopt the bearing of said structure to come connecting stator and rotor, this single bearing can bear axial force and radial load simultaneously like this, so the effect needing two bearings just can reach before only needing a single bearing just can reach, not only decrease cost, and because only need a bearing, so do not need to consider concentric problem, so install very convenient yet.
As preferably, described stator support comprises the first stator support and the second stator support, circumferentially multi-disc reinforcement is evenly provided with between the outer ring of described first stator support and the inner ring of the second stator support, and described first stator support is cup type structure, the described bearing supports other end is fixedly connected with by securing member with the bottom of the first strutting piece, and described stator is connected by hot jacket interference fit with the second strutting piece.The structural strength arranging stator support is like this higher, and radiating effect is better, and installs more convenient.
As preferably, described first stator support, near being provided with a labyrinth seal assembly for preventing rainwater dust from entering motor between rotor one end and rotor, is respectively equipped with a labyrinth seal assembly for preventing rainwater dust from entering motor between described second stator support two ends and rotor.Multiple labyrinth seal assembly is set between stator support and rotor, effectively can prevents rainwater dust etc. from entering motor like this, affect the normal operation of motor.
As preferably, between described bearing outside and bearing plate, be provided with a bearing seal assembly.Arrange like this and can effectively prevent rainwater dust etc. from entering in bearing, affect the normal rotation of bearing.
As preferably, described rotor bottom is provided with multiple louvre.Such thermal diffusivity that can strengthen motor.
