Description
Technical field
The present invention relates to a kind of pick-up unit, especially a kind of pick-up unit that is used for AC external rotor type motor stator test run.
Background technology
In the existing three phase alternating current motor production run, the winding iron core rule is arranged after, whether correctly generate rotating magnetic field in order to check its rule, whether its rotating magnetic field of test of all will switching on exists.The detailed process of its detection is: the stator of Y series threephase asynchronous (belonging to inner rotor type motor) for example, energising back stator internal circular surfaces produces rotating magnetic field, a general available steel ball is put into the stator internal circular surfaces, after stirring by the direction of rotating magnetic field with hand, the rotation that steel ball does not just stop at the expulsive force effect lower edge of rotating magnetic field stator internal circular surfaces.If do not rotate, just check out this to have the winding iron core rule incorrect, the processing of can before having winding iron core baking insulating oil to solidify winding, doing over again.The defective of this kind characterization processes is: because the rotating magnetic field of external-rotor-type three phase alternating current motor is the cylindrical that results from winding iron core, so can not use the test technology of inner rotor type motor.
Summary of the invention
At above-mentioned situation, the purpose of this invention is to provide a kind of pick-up unit that is used for AC external rotor type motor stator test run, it was both rational in infrastructure, practical, at first adopted the test working of this device to test AC external rotor type motor stator again in this field.
For achieving the above object, a kind of pick-up unit that is used for AC external rotor type motor stator test run, its base center is provided with vertical axis of a cylinder, the top of this axis of a cylinder is provided with the supporting whirligig, one quoit is fixed on the supporting whirligig through connecting the grizzly bar suspension, and this quoit inner diameter d has been sleeved on the winding iron core outer radius and has kept uniform gap.
For implementation structure optimization, its further step is:
The outer diameter D of base is less than the internal diameter that winding iron core is arranged.
The high H of quoit equals to have the height of winding iron core.
The inner diameter d of quoit is greater than the external diameter that winding iron core is arranged.
The present invention is used in the base center and establishes vertical axis of a cylinder, establish the supporting whirligig in the top of axis of a cylinder and connect firmly quoit through being connected the grizzly bar suspension, this quoit inner diameter d is sleeved on the winding iron core outer radius and keeps the technical scheme of uniform gap, has overcome existing test technology and can not adapt to the defective that external rotor electric machine detects.
The beneficial effect that the present invention is had compared to existing technology:
(1) change steel ball and detect to device detects, set up the device of perfect in shape and function for the three-phase alternating current external rotor type motor stator test run detects first, it provides guarantee for improving this field three-phase alternating current external rotor type motor stator test run accuracy of detection and detection efficiency;
(2) base is adjustable, can make the inner diameter d of quoit and the external diameter that winding iron core is arranged keep the gap even, and the high H of quoit equates with the height that winding iron core is arranged;
(3) simple in structure, this structure with the inner diameter d of quoit greater than the winding iron core external diameter is arranged, be that the external diameter that the inner diameter d of quoit equals winding iron core adds rational electromagnetic induction air gap, the high H of quoit equals to have the height of winding iron core, it is easy to manufacture, use, quick for installation, cost of products is low, and is economical, practical.
It is suitable for the detection of all kinds of three-phase alternating current external rotor type motor stator test runs.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 2 is the front view of the embodiment of Fig. 1.
Among the figure: 1, base, 2, axis of a cylinder, 3, the supporting whirligig, 4, quoit, 5, connect grizzly bar, 6, winding iron core arranged, 7, the gap.
Embodiment
Referring to accompanying drawing, a kind of pick-up unit that is used for AC external rotor type motor stator test run, vertical axis of a cylinder 2 is established at base 1 center, and for ease of the installation of base 1, the outer diameter D of base 1 is less than the internal diameter that winding iron core 6 is arranged; Supporting whirligig 3 is established on the top of axis of a cylinder 2; One quoit 4 is fixed on supporting whirligig 3 through connecting grizzly bar 5 suspensions; In order to improve accuracy of detection, the high H of this quoit 4 equals to have the height of winding iron core 6, and the inner diameter d of quoit 4 has been sleeved on quoit 4 inner diameter d winding iron core 6 outer radius and has kept uniform gap 7 greater than the external diameter that winding iron core 6 is arranged.
During use, earlier base 1 and axis of a cylinder 2 vertically are placed on the plane platform, to there be winding iron core 6 to be inserted on the base 1 again from axis of a cylinder 2, at last with quoit 4 and connection grizzly bar 5, supporting whirligig 3 has been sleeved on winding iron core 6 outer radius and the axis of a cylinder 2, adjust base 1, the inner diameter d of this quoit 4 keeps uniform gap 7 with the external diameter that winding iron core 6 is arranged, quoit 4 high H equal to have the high of winding iron core 6 or both height to equate, after the extension line connection three-phase alternating-current supply of winding iron core 6 will be arranged at last, have the outer round surface of winding iron core 6 external diameters to produce rotating magnetic field, quoit 4 inductions have the rotating magnetic field of winding iron core 6 and rotate.
Below only be preferred embodiment of the present invention, according to above-mentioned design of the present invention, those skilled in the art also can make various modifications and conversion to this, and for example, quoit hangs modification and the conversion that is fixed on supporting whirligig etc. through connecting grizzly bar.Yet similar this conversion and modification all belong to essence of the present invention.
