Description
Technical field
The present invention relates to a kind of birotor permanent magnetic motor, in particular on a kind of high-power birotor permanent magnetic motor from
The terminals of external power supply are connected to the structure for the entire transmitting electric energy that fax is given to internal rotor three-phase windings.
Background technique
The structure of double-rotor machine is mainly made of internal rotor, outer rotor, and internal rotor is threephase armature winding, and outer rotor is
Permanent magnet needs when motor operation the external three phase mains that provides to give threephase armature winding power, since internal rotor is rotary body, need to lead to
It crosses brushgear and slip ring assembly introduces external three phase mains；The power supply introducing of traditional double-rotor machine is on electric motor end cap
Power supply is set and introduces binding post, binding post passes through connecting lead wire again and links together with brushgear, general on electric motor end cap
There are three binding posts for setting；But for powerful double-rotor machine, the supply current of the three-phase windings on internal rotor require compared with
Greatly, increase slip ring lead-out wire usually on slip ring, to meet the high current requirement of three-phase windings, generally wanted on every phase slip ring
Multiple brushes are arranged to be shunted, the electric current on multiple brushes of every phase slip ring is respectively connected to the binding post on electric motor end cap
On, which links together with external power supply power supply again；This requires the galvanization abilities of the binding post on electric motor end cap
Want larger, the structure size of the binding post certainly will be required to become larger, be just able to satisfy the requirement that high current passes through, but the volume of motor and
Structure be it is limited, the total of motor cannot be increased, therefore existing to meet requirement of the binding post by high current
Birotor power supply structure be unable to satisfy the high current of high-power double-rotor machine threephase armature and required by electricity.
Summary of the invention

The present invention is to solve the above technical problem by the following technical programs:
The present general inventive concept is: in the outside of slip ring assembly and brushgear, setting collector ring replaces traditional wired column, uses
In introducing high current, after collector ring is shunted high current by multiple brush wires, it is introduced between on multiple brushes, multiple brushes
It is connected as the high-power electric current needed for the phase armature winding provides with certain phase slip ring, that is, it is electronic to meet high-power birotor permanent magnetic
The high current requirement of inboard rotor armature, but no need to increase the volume of motor and structures.
A kind of high-power birotor permanent magnetic motor by electric structure, including electric machine casing, be provided in electric machine casing
Outer rotor and internal rotor are provided with internal rotor armature winding on internal rotor, are provided with slip ring assembly in the shaft of internal rotor,
Brush is provided on slip ring assembly, brush is arranged on brush holder, and brush holder is connected on electric machine casing, internal rotor armature winding
It is electrically connected by armature winding lead wire with slip ring assembly, has been equally spaced arc on the outer circle side of brush holder
Cross-over block is provided with collector ring on the arc cross-over block being positioned apart from, and power supply is provided on collector ring and introduces copper
Row, is provided with drainage thread between collector ring and brush.
6-8 brush is provided on slip ring assembly；Protective cover is provided on the outer circle side of collector ring.
The configuration of the present invention is simple can meet the power reguirements of different high-power spinner motors, and collector ring is by electric energy power
Greatly, power supply structure is safe and reliable.
