Permanent magnetism not brushes the wheel hub electrical machinery

Because the magnetoelectric machine the slot effect produces the detent torque and the torque pulsation, is especially remarkable in the rotational speed low wheel hub electrical machinery. Not brushes the direct current machine commonly used integer trough winding pitch to be big, and the winding overlaps mutually, causes the winding over-hang to be very big. This article hub motor the contrast research regarding the number of pole-pairs different integer trough winding electrical machinery model and the score trough winding electrical machinery model's winding and the detent torque. The theoretical analysis indicated that the score trough winding can reduce the electrical machinery detent torque and the torque pulsation effectively, reduces the winding over-hang length. Finally the use finite element simulation has carried on the confirmation to the theoretical analysis.

Carboxymethylcellulose important characteristic

The CMC food grade important characteristic important characteristic is the shape becomes the macroviscosity colloid, the solution, has the coherence, dewaters, the flowing, the breast decompose disperses, the size enlargement, guarantees the water, the protective colloid, the thin membrane formation, acidproof, bears the salt, hangs and so on characteristics muddy, and the physiology is harmless, because this in domain productions and so on food, medicine, date, petroleum, papermaking, spinning and weaving, building to widespread should use. Is popular the happy carboxymethyl cellulose is the specialized production and sells each kind of cellulose, the cellulose may take the minute as: The well drilling putty thick liquid uses, to make the balm powder to use, the ceramics use, the papermaking uses, the spinning and weaving uses, food uses and so on. The level simple flat structure is the most advantageous place which we organize. Thus, between the member can communicate, the exchange mutually well, study and encourages, the greatest degree realizes the CMC battery grade sharing, and maintains throughout to the outside makes the rapid reaction to be able the strength. Our company improved the enterprise environment diligently, the reform personnel machine-made shape has become the enterprise formidable cohesive force and the battle efficiency

The round loom two kinds stop the latitude automatically the original principle

Old style electromagnetic induction installment:

Is the installment has the pro and con circular loom in the weft bobbin the beginning of base, the round loom starts, the bobbin starts to rotate, like this cuts the magnetic line of force to produce the electrical signal the launcher to send through the ammunition clip end shoots, (on leads link) in the ammunition clip vertical upper extreme above to have one to accept the installment (and has holding wire to connect apparatus cabinet), like this has not monofilament extrusion will receive 6 signals (six shuttles machine), will receive 8 signal numbers (eight shuttles machine) like the fruit latitude to break the bobbin to stop transfers little will receive a signal, in the apparatus cabinet PLC will send the signal engine off. The latitude has been simpler, the weft tensity adjustment must be the steel wire brush-like, when the weft uses up the bobbin exposed comes out, steel wire brush immediate contact zipper machine, closed circuit, signal feedback, direct engine off.

Multi-while going along straight forward system drawing machine control system's design

The tape extruder craft is one in metallurgy production important links, the drawing machine realizes the drawing process major installation. At present in drawing machine's prime task way, the multi-while going along straight forward system drawing machine is the most commonly used one kind. It requests to draw in the process many wiredrawing electrical machinery by the high speed, the high accuracy, high coordinatively realizes the multi-electrical machinery's linkage movement. And the guarantee system has the good dynamic property and the resistance to interference. The tape making machine drawing machine control mode uses the cocurrent to modulate velocity and to simulate the quantity control mode usually. But this control mode has the anti-jamming to be bad, the dynamic property is not ideal, shortcomings and so on multi-electrical machinery coordinative insufficiency, specially when over oversized time is very difficult to carry on the tape stretching line, thus causes the silk size of twine to be uneven, even breaks the silk.
