Abstract
The utility model discloses a rotor of a series excited machine. The rotor comprises coils and commutator copper sheets, wherein each coil is connected with each commutator copper sheet by an enamelled wire, and is connected with a copper wire formed by multiple strands of copper wires through a copper belt cold rolling point at the front end of a welding point of each enamelled wire and each commutator copper sheet; and the copper wires and the enamelled wires are welded with the commutator copper sheets. According to the rotor of the series excited machine, the structure is reasonable, a section of connecting wire is added on each group of the enamelled wires by which one of the coils is connected with one of the commutator copper sheets, the mechanical strength of the connecting wires is enhanced, the service life of the series excited machine is prolonged manyfold, and the application value of an electric tool can be increased greatly when the rotor is applied to the electric tool.
Description
Technical field
The utility model relates to a kind of series excited machine rotor.
Background technology
Tradition series excited machine rotor; All be enamelled wire and commutator with every group of coil be welded direct to commutator copper sheet on; The rotor that this technology is made extremely under the condition of severe, uses the short time at operational environment; The phenomenon that the enamelled wire of copper segment root will occur rupturing causes rotor to damage and makes the motor cisco unity malfunction.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the series excited machine rotor of motor long service life.
The technical solution of the utility model is:
A kind of series excited machine rotor comprises coil, copper segment, and coil is connected with copper segment through enamelled wire, it is characterized in that: enamelled wire with copper segment pad front end, be connected with the copper cash of forming by the multiply annealed copper wire through the cold rolling point of copper strips; Said copper cash and enamelled wire weld with copper segment together.
The utility model is rational in infrastructure; Every group of coil connects on the enamelled wire of copper segment, increases by one section connecting line, to strengthen the electric conductivity and the mechanical strength of connecting line; Can significantly improve the useful life of motor, be used for to improve greatly on the electric tool use value of electric tool.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
