Abstract
The invention discloses a rotor of a series excited machine. The rotor comprises a coil and a commutator copper sheet, wherein the coil is connected with the commutator copper sheet by an enamelled wire, the front end of a welding point of the enamelled wire and the commutator copper sheet is connected with a copper wire formed by multiple strands of copper wires and a copper belt cold rolling point; and the copper wires and the enameled wire are welded with the commutator copper sheet. According to the rotor of the series excited machine, the structure is reasonable, each group of coil is connected on the enamelled wire of the commutator copper sheet, so that a section of connecting wire is additionally arranged, so that the mechanical strength of the connecting wire is enhanced, the service life of the machine is prolonged manyfold, the rotor is used for an electric tool, so that the using value of the electric tool is increased greatly.
Description
Technical field
The present invention 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
The object of the present invention is to provide a kind of rational in infrastructure, the series excited machine rotor of motor long service life.
Technical solution of the present invention 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 present invention 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 present invention is described further.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
