Abstract
The invention discloses a commutating pole structure for a direct current motor, which comprises a wound upper commutating pole coil, a wound lower commutating pole coil, a stacked commutating pole iron core and a pressing plate, wherein the upper and lower commutating pole coils are sleeved on the commutating pole iron core; the upper and lower commutating pole coils are clamped by a circular steel which passes through the commutating pole iron core; a annular insulation plates is respectively arranged between the upper commutating pole coil and the circular steel and between the upper commutating pole coil and the lower commutating pole coil; the pressing plate is arranged under the commutating pole iron core; a rectangular insulation plate is arranged between the commutating pole iron core and the pressing plate; and the commutating pole iron core and the pressing plate are fixed with bolts. The commutating pole structure for a direct current motor has compact and firm structure and, has strong integrity and obvious action effect. When the motor is in short circuit caused by instant fault, the structure can be used for well protecting the commutating pole from being influenced and preventing the commutating pole from collapsing towards one side under the action of an overlarge magnetic pull force.
Description
Technical field
The present invention relates to the commutating pole structure of DC motor.
Background technology
The DC motor commutating pole structure of common Z series after iron core and the mounting coil, normally with the colligation of insulated binding band, reaches the globality of compole core and coil; But direct current machine for Z800 ~ Z1000, continuous increase along with capacity motor, when motor breaks down instantaneous short circuit, at this moment the electric current by commutation coil increases suddenly, be subjected to the influence of stray field, the suffered magnetic pull of coil this moment will increase moment, because structural shortcoming, commutating pole just can cause badly damaged along with pulling force collapses to a side.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, guaranteeing motor thereby provide a kind of
Under maximum power, commutating pole can bear big relatively magnetic pull, and sound construction is reliable, guarantees the commutating pole structure of the normal direct current machine that uses of motor.
Technical scheme of the present invention is as follows:
A kind of commutating pole structure of direct current machine, comprise the good upper and lower commutation coil of coiling, the compole core that laminates and pressing plate, upper and lower commutation coil is sleeved on the compole core and by the round steel that passes compole core upper and lower commutation coil is blocked, between last commutation coil and the round steel, all be lined with annular insulation board between last commutation coil and the following commutation coil, pressing plate is arranged on the compole core below and is provided with the rectangle insulation board between the two, and pressing plate and compole core pass through screw.
Further advance, the two ends of compole core are with commutating pole pad and cushion block jam-pack, and with screw commutating pole pad and cushion block and compole core are fixed together.
Further, described screw is the galvanized steel sunk screw.
Useful technique effect of the present invention is:
Compact conformation of the present invention, firmly, globality is strong, and action effect is obvious; In the short circuit of motor generation transient fault, when the electric current that passes through was excessive, although suffered magnetic pull is very big, this kind structure also can be good at protecting commutating pole unaffected, prevented that commutating pole from collapsing owing to magnetic pull is excessive on one side.

Fig. 1 is a commutating pole structural representation of the present invention;
Fig. 2 is the side-looking structural representation of Fig. 1.
Mark is illustrated as among the figure: 1.1, the upper and lower commutation coil of 1.2-; 2-commutating pole pad; The 3-cushion block; 4.1, the 4.2-screw; The 5-compole core; The 6-round steel; 7-annular insulation board; 8-rectangle insulation board; The 9-pressing plate.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes the good last commutation coil 1.1 of coiling, following commutation coil 1.2, compole core 5 that laminates and pressing plate 9, commutation coil 1.1 and passing between the round steel 6 of compole core 5, on, following commutation coil 1.1,1.2 between be provided with annular insulation board 7, treat, following two commutation coils 1.1, after 1.2 suit puts in place, process the position of two row's screwed holes in advance in compole core 5 bottoms, rectangle insulation board 8 and pressing plate 9 have successively been filled up, utilize galvanized steel sunk screw 4.1 that compole core 5 and pressing plate 9 are fixed, and screw 4.1 all need be cut a hole hair, to guarantee smooth surface; For preventing to be subjected to displacement between commutation coil 1.1 and the compole core about 5, with commutating pole pad 2 and cushion block 3 jam-packs, and be fixed with galvanized steel sunk screw 4.2 at the two ends of compole core 5.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
