Abstract
The utility model discloses a non-salient-pole type shaded-pole motor, which comprises a main winding and a shaded-pole winding with certain electrical degree differences embedded into a stator groove; a capacitor is in series connection between the both ends of the winding of the shaded-pole winding; the shaded-pole winding can obtain the induced potential and the leading current when the main winding is electrified, so as to benefit the main winding to excite and reduce the exciting current and power of the motor; thereby reaching the high-efficiency operation while obtaining the starting torsion to lead the motor to be rotated relatively to the stator at the same time. The design of the motor can keep the interchangeable structure between the shaded-pole motor and the traditional capacitance operating motor, so as to emphasize the universality between each other and also reach the efficiency and volume similar to the capacitance operating motor; the production and operation is more convenient, the production cost is helpfully reduced, and the motor efficiency is improved.
Description
Technical field
The utility model relates to a kind of motor, especially relates 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.
The utility model content
Based on above-mentioned many deficiencies, the purpose of this utility model is to provide a kind of high efficiency hidden pole type motor with cup rotor, keeps 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, save cost.
For realizing this purpose, the utility model is taked following technical scheme:
Hidden pole type motor with cup rotor of the present utility model, 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 utlity model has following advantage: at first, motor of the present utility model 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 the utility model hidden pole type motor with cup rotor.
Embodiment
Seeing also Fig. 1 is described in detail the utility model:
Hidden pole type motor with cup rotor of the present utility model 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.
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 utility model, 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.
