For the rotor of above-mentioned electric rotating machine, also exist the problem of cost and design aspect, corresponding as the armature frame of stator for the magnetic pole of alternately arranging with stator, must be provided with the axial notch of relative dense arrangement, and armature winding also will be arranged according to the polarity of stator and twine, simultaneously, for the winding that satisfies thereon can have electric current to pass through simultaneously, two leading-out terminals of each coil must be connected to a commutator segment, so, the structure of this kind motor is comparatively complicated, be not easy to processing, thus the raising that brings cost.
In addition, the motor of said structure is not because the rotating magnetic field that stator provided is equally distributed at magnetic loop, so, the armature frame can produce relatively large eddy current loss and magnetic hysteresis loss, simultaneously, because of the existence of armature frame teeth groove, its air-gap flux can produce big or small pulsating and the problem of vacillating now to the left, now to the right also can cause certain loss, so the mechanical efficiency of this kind motor is relatively low.
Summary of the invention:
Task of the present utility model provides a kind of mode that does not almost have air gap between magnetic pole of utilizing and provides rotating magnetic field for rotor, so that it reaches high power output and electric rotating machine simple in structure is arranged.
The electric rotating machine that the utility model proposed, support with a band circular hollow, in described support is hollow, be provided with stator and rotor, described stator is arranged installation and reeded stator frame of peripheral band and the excitation winding that is wrapped in each stator frame groove by one group along the hollow circumferencial direction of support, and the brush that is connected with two terminals of described excitation winding respectively constitutes; Described rotor is equipped with the armature frame of the commutator that can contact with brush and is wrapped in the interior armature winding formation of described armature frame parallel groove by parallel groove and the two ends along the hollow axially spaced-apart preset distance of stator.
Described stator frame is by a long limit and a minor face, and vertical edge form be similar to the I-shaped body, and by stator frame and the two ends of twining the stator that excitation winding thereon forms also be separately installed with annular baffle, and two terminations of the excitation winding lead on each stator frame are connected with brush after passing baffle plate respectively.It is identical that stator is divided into number along hollow diameter, opposite polarity two groups of stator frames and twine thereon excitation winding, and two lead terminations of each excitation winding are extended the baffle plate at its two ends respectively and are connected with brush.
Two ends of described armature frame are provided with the commutator that is made of two semicircle conductors, and two commutators are formed a round with keeping at a certain distance away, are separately installed with rotation axis in this round centre.
Described rotation axis and armature frame axially be provided with the through hole that can allow current supply line to pass, and this current supply line is electrically connected in support respectively with excitation winding and armature winding by commutator.
The stator of the electric rotating machine that the utility model proposed adopts the excitation winding of arranging along support circular hollow direction, make it between winding, not have air gap, so, the stator of this kind structure can be rotor rotating magnetic field very uniformly is provided, and what stator adopted is I-shape construction, and its cost of manufacture is relatively low; And rotor also has only quite simple commutator of structure and armature frame and armature winding to constitute, so the structure of rotor is also very simple; Simultaneously,, can not produce the phenomenon of eddy current loss and magnetic hysteresis loss,, use this kind motor to economize on electricity so the mechanical efficiency of this kind motor is higher relatively because the formed rotating magnetic field of the stator of this kind structure is very even.
