Abstract
The invention discloses a non-salient pole shaded-pole motor, comprising a main winding and a shaded-pole winding which are embedded in a stator slot with different electrical angles; a capacitor is connected in series between the two ends of the wire winding of the shaded-pole winding; when the main winding is energized, the shaded-pole winding obtains an induced potential and a leading current to help the main winding excite, and the excitation current and power of the main winding are reduced; therefore a startup torque is obtained to lead the rotor of the motor to rotate correspondingly to a stator; meanwhile, working in high efficiency is realized. The design of the motor has the advantages that the shaded-pole motor can interchange with a traditional capacitive operation motor, so the generality of the two motors is projected, and the efficiency and volume of a capacitive operation motor can be approximately realized; therefore production and operation are more convenient, reduction of production cost is facilitated and motor efficiency is improved.
Description
Technical field
The present invention relates to a kind of motor, especially relate to a kind of hidden pole type motor with cup rotor.
Background technology
Shadedpole motor is the simplest a kind of in the one-way communication motor, adopts cage modle skewed slot cast-aluminum rotor usually.It is divided into salient pole type shaded pole motor hidden pole type shaded pole motor again according to the difference of stator contour structures.
The stator core profile of salient pole type shaded pole motor is square, rectangle or circular field frame, and magnetic pole protrudes, and one or more short circuit copper rings that help out is all arranged, i.e. the split-pole winding on each magnetic pole.Concentrated winding on the magnet limbs is as main winding.The salient pole type shaded pole motor is simple in structure, but efficient is relatively low, and can not be general between its structure and the capacitor-operated motor.
The stator core of hidden pole type shaded pole motor is identical with the iron core of common single-phase motor, its stator winding adopts distributed winding, main winding is distributed in the stator slot, the split-pole winding is without the short circuit copper ring, but be inlaid in the stator slot (be about total groove number 1/3) with thicker enamelled wire coiled distributed winding (short circuit voluntarily after the series connection), play assisted group, main winding and split-pole winding in the space at a distance of certain angle.
After the main winding energising of shaded pole motor, the split-pole winding also can produce induced current, makes magnetic pole of the stator be covered the magnetic flux of part and not cover the direction rotation of part to the quilt cover part by the split-pole winding.
But still there is inefficient problem in present hidden pole type motor with cup rotor.Its efficient is suitable with the salient pole motor with cup rotor.
Summary of the invention
Based on above-mentioned many deficiencies, the object of the present invention is to provide a kind of high efficiency hidden pole type motor with cup rotor, keep common hidden pole type motor with cup rotor versatility, the advantage of simplified manufacturing technique because the efficient height has reduced the material consumption of motor, is saved cost.
For realizing this purpose, the present invention takes following technical scheme:
Hidden pole type motor with cup rotor of the present invention, comprise the main winding and the split-pole winding that are flush-mounted in the stator slot and differ certain electrical degree, be serially connected with capacitor between the coiling two ends of split-pole winding to form leading short circuit current, help the main winding excitation, the exciting current and the power of motor have been reduced, the split-pole winding obtains induced potential and capacity current when main winding is switched on, make the rotor relative stator of motor be rotated efficient simultaneously operation at the acquisition starting torque.Described main winding shared volume in stator slot is 3/6 to 5/6.Described capacitor is the perhaps electrochemical capacitor of differential concatenation of alternating current.This motor has the punching identical with capacitor-operated motor, and close efficient and exerting oneself can replace capacitor-operated motor in some occasions.Versatility height structurally.
Compared with prior art, the present invention has following advantage: at first, motor of the present invention can obtain higher efficient, levels off to the efficient of capacitor-operated motor; Secondly, can exchange structure with capacitor-operated motor; Moreover the use of common punching makes it have stronger versatility on manufacture craft, and this structure also can make copper consumption save nearly 1/4; In addition, simple in structure, easy-to-connect, workable.
Description of drawings
Fig. 1 is the electrical principle schematic diagram of hidden pole type motor with cup rotor of the present invention.
Embodiment
The present invention will be described in detail to see also Fig. 1:
Hidden pole type motor with cup rotor of the present invention adopts the punching (not shown) identical with known capacitor-operated motor, so that keep versatility each other, and interchangeable each other structure.
It is (not shown that this hidden pole type motor with cup rotor has the stator slot of being inlaid in, main winding 2 and split-pole winding 4 down together), main winding 2 differs certain electrical degree with split-pole winding 4, and the difference on this electrical degree is adjustable, also is that those skilled in the art are known.
Main winding 2 occupies 2/3 of stator slot overall volume, and the volume of split-pole winding 4 then only accounts for part to tens/one of main winding 2 volumes, is determined on a case-by-case basis.
Capacitor 6 of coiling two ends serial connection of split-pole winding 4, after these capacitor 6 serial connections, form leading short circuit current, this mode had both played the effect of the short circuit copper ring of traditional salient pole type motor with cup rotor, can help the main winding excitation again, obtain more excellent efficient.Particularly: when main winding 2 energisings, split-pole winding 4 will obtain an induced potential and induction capacity current, thereby obtain starting torque and magnetic assist electric current, and the drive rotor is rotated with respect to stator and efficiently operation.Split-pole winding 4 had both formed the same short-circuited conducting sleeve of common salient pole winding, and and for example asynchronous generator is the same, because split-pole winding 4 has obtained capacity current, the effect of additive excitation was arranged, and had reduced the exciting current of motor, can improve efficiency of motor widely.
Preferable scheme, this capacitor 6 adopts the electrochemical capacitor of two differential concatenations, to obtain the low pressure large bulk capacitance, but and this main winding 2 shared volume flexible in stator slot, especially occupy regulate between the stator slot 3/6 to 5/6 the most suitable, can realize Sine distribution, reduce harmonic loss, split-pole winding 4 shared volumes then can be obtained according to known account form debugging by those skilled in the art.
This design of the present invention, make hidden pole type motor with cup rotor keep interchangeable structure both and between traditional capacitor-operated motor, may replace capacitor-operated motor in some occasions again, enlarge the purposes of motor, given prominence to versatility, can keep the structure of simplifying again, thereby make production, the operation more convenient, also help reducing production costs.
