Plunger

The specific roller reducer has been working under the condition of communication and alternating current. The loss of output power is not only on the resistor of the electromagnetic coil, but also on the iron integrated chip when the alternating current is magnetized. Eddy current loss is caused by eddy current loss in the whole process of magnetization of iron integrated chip. The size of such loss is proportional to the total area surrounded by the hysteresis loop of the raw material. The hysteresis loop of silicon steel is narrow, and the eddy current loss of transformer core using it as transformer is small, which can greatly reduce its scalding level.

When the transformer works, there is alternating current in the solenoid coil of roller pump, and the magnetic flux caused by it naturally changes alternately. The flux of this transformation causes the induced electromotive force in the transformer core. The induced electromotive force caused by iron integrated IC is applied in the plane of vertical bisector flux direction, and the eddy current loss makes the transformer core hot.

In order to reduce the eddy current loss, the transformer core of the transformer is folded into ferrite cores with mutual insulation layer, so that the eddy is in the control circuit of the slender shape, and the resistor on the eddy channel is expanded according to the smaller cross section; in addition, the silicon in the silicon steel makes the resistance of the raw material expand, which also has the effect of reducing the eddy.
