Abstract
The utility model relates to a short circuiting ring of a shaded pole motor, which comprises the front support and the rear support of the shaded pole motor. Rotor assemblies, stator assemblies and coil assemblies are arranged in the front support and the rear support. The rotor assemblies in the front support and the rear support comprise cast-aluminum rotors, shafts and gaskets, and the stator assemblies in the front support and the rear support mainly comprise short circuiting rings and main stator cores. The short circuiting rings are arranged on the salient magnetic poles of the main stator cores of the stator assemblies; and the coil assemblies in the front support and the rear support are arranged on the salient magnetic poles of the main stator cores and are distributed in a stator slot. The utility model has the advantages that aluminum materials are adopted so as to replace expensive red copper or other metallic copper materials, and thereby, the production cost is greatly reduced and the valuable red copper materials of strategic resources are saved for China. The short circuiting ring can be widely applied to assorted shaded pole motor devices in various household appliances.
Description
Technical field
The utility model relates to a kind of kit of motor with cup rotor, especially relates to a kind of motor with cup rotor short-circuited conducting sleeve that adopts the low internal resistance electric conducting material of aluminium matter to make.
Background technology
Motor with cup rotor comprises rotor and two critical pieces of stator, described rotor adopts cage modle skewed slot cast-aluminum rotor and axle usually, its core magnetic pole of described stator protrudes, the short circuit copper ring that all has one or more to help out on the magnetic pole, it is the split-pole winding, described short-circuited conducting sleeve must be made by low-resistance metal material, its effect is the part magnetic field short circuit with the split-pole winding, the split-pole winding can produce induced current, cover sub-fraction main pole magnetic field, thereby produce another and the dephased split-pole of main field magnetic field, the concentrated winding on the magnet limbs is as main winding, and main winding is distributed in the stator slot.Main winding and split-pole winding in the space at a distance of certain angle, after the main winding energising, just formed a circle or elliptical rotating field with the interaction of split-pole winding, made magnetic pole of the stator be covered the magnetic flux of part and cover part to quilt cover direction rotation partly by the split-pole winding.
In order to reduce the temperature rise that described short-circuited conducting sleeve induced current is produced, require described short-circuited conducting sleeve to adopt low-resistance material, at present, the manufactured materials and the method for manufacturing technology of the short-circuited conducting sleeve in the domestic motor with cup rotor that generally uses are to be finished through punching out as raw material by red copper sheet material, yet as raw-material red copper is the strategic resource of national precious, and price is higher; With red copper material short-circuited conducting sleeve and be widely used in the motor with cup rotor supporting in all kinds of household electrical appliance, not only increase product cost, also be very unfortunate really.
The utility model content
The purpose of utility model is exactly in order to overcome above-mentioned weak point of the prior art, and a kind of motor with cup rotor short-circuited conducting sleeve that adopts the low internal resistance electric conducting material of aluminium matter with alternative metals copper is provided.
The utility model is by providing a kind of motor with cup rotor short-circuited conducting sleeve with following manufactured materials and method of manufacturing technology to realize, it comprises fore-stock, the after-poppet of described motor with cup rotor, be provided with rotor assembly in described fore-stock, the after-poppet, stator module and solenoid component.Rotor assembly in the described forward and backward support is made up of cast-aluminum rotor, axle and pad, in the described forward and backward support stator module mainly form by short-circuited conducting sleeve and main stator iron core.Solenoid component in the described forward and backward support is arranged on the main stator iron core magnet limbs, be distributed in the stator slot, an end of solenoid component is provided with the lead-out wire that connects the AC power winding coil, after lead-out wire is connected AC power, make the armature spindle rotation, and the output torque drives equipment work.
Described short-circuited conducting sleeve is to be made by aluminum material, and described short-circuited conducting sleeve is by the cold punching technology moulding.
Described short-circuited conducting sleeve is arranged on the protrusion magnetic pole of main stator iron core of described stator module.
Compared with prior art, the invention has the advantages that: 1. adopt aluminum to substitute red copper, reduce production costs greatly; 2. be the red copper material that country saves valuable strategic resource; 3. can be widely used in the motor with cup rotor device supporting in the household electrical appliance miscellaneous.
Description of drawings
Fig. 1, Fig. 2 are the structural representations of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1, Fig. 2 show execution mode of a kind of motor with cup rotor short-circuited conducting sleeve of the utility model.It comprises the rotor assembly that is provided with in described fore-stock 1, the after-poppet 2, rotor assembly has stator module outward, rotor assembly in the described forward and backward support is provided with cast-aluminum rotor 3, axle 4 and pad to be formed, and described stator module is provided with short-circuited conducting sleeve 5 and forms with main stator iron core 8.。One end of described solenoid component 6 is provided with the winding coil lead-out wire 7 that connects AC power.After lead-out wire 7 is connected AC power, make axle 4 rotations.
Short-circuited conducting sleeve 5 is that the shape of short-circuited conducting sleeve 5 can be miscellaneous by the aluminum material making and by the cold punching technology moulding.
Short-circuited conducting sleeve 5 is arranged on the protrusion magnetic pole of the main stator iron core 8 of described stator module.A kind of motor with cup rotor short-circuited conducting sleeve of the utility model is made to substitute the effect of red copper by aluminum material, and is pretty good through the practical measurement effect.
For example: when external diameter is 58 millimeters a motor with cup rotor when adopting the short-circuit piece that aluminum material makes, be to work under 220 volts the power supply at alternating voltage, its output torque is 74 to restrain * centimetre; When the motor with cup rotor of same outer diameter as and thickness adopts its output torque of short-circuited conducting sleeve of red copper material is * centimetre of 80 gram.Its output torque of short-circuited conducting sleeve that promptly adopts aluminum material to make slightly reduces than the short-circuit piece output torque that adopts the red copper material, and its reduced rate is about 8 percent, but output torque still is much higher than * centimetre of 68 gram of the industry standard of China; And production cost significantly reduces.
