Summary of the invention:
The purpose of this utility model provides a kind of series excited machine rotor that can effectively reduce the electric machine structure noise.
The purpose of this utility model is achieved by following technical proposals.
A kind of series excited machine rotor, comprise rotor core, coil windings, rotating shaft and commutator, rotor core is installed in the rotating shaft, commutator is installed in rotating shaft one end, have line embedding groove on the rotor core, on the internal face of line embedding groove, be equipped with insulation tank paper, coil windings is embedded into the line embedding groove the inside and is insulated the groove paper bag, notch place at line embedding groove is provided with slot wedge, space between each enamelled wire of composition coil windings is filled with insulating varnish, and near the idle area that forms the notch of line embedding groove fills up filler.
Above-mentioned described filler can form one with slot wedge.
Above-mentioned described filler can be a block independently.
Above-mentioned described filler can be made up of attachment flaps and the attachment that sticks on the attachment flaps.Attachment is the insulating varnish that solidifies, and attachment flaps is the paper shape thing of arc.
The utility model compared with prior art, have following effect: 1) space between each enamelled wire of composition coil windings is filled with insulating varnish, near the idle area that forms the notch of line embedding groove fills up filler, when the rotor high-speed running, axial blowing can not be passed through the gap of the line embedding groove of rotor, thereby can not form sharp-pointed noise; 2) in the idle area on line embedding groove top, attachment flaps is set, has strengthened adsorption capacity, simplified technology insulating varnish; 3) shaped design of attachment flaps is an arc, and adsorption surface area was bigger when insulating varnish was injected, and attachment flaps is best to the adsorption effect of insulating varnish; 4) filler can form one with slot wedge, makes structure, technology simpler.
