(1) In this research a kind of electrical motor pole piece was introduced, whose model was made by the CAD technology. The forming process of electrical motor pole piece was simulated by FEM software.

(2) Also because of closely spaced pole piece and the associated capability of focusing low-voltage beams, folded waveguide circuit is well suited for light weight applications.

(3) The device consists of a single-shot molded plastic package that includes a samarium cobalt pellet, a pole piece , and a Hall effect IC that has been optimized to the magnetic circuit.

(4) We use the finite-element method for calculating the magnetic field strength in pole piece tooth space, where its shape is complicated and changeable in the paper.

(5) The utility model discloses a device for removing dust during the shearing of a lithium ion battery pole piece, in particular to a brush device of a shearing machine.

(6) The manufacturing method of the polymer lithium ion battery comprises steps of pole piece preparation, polymer coating, nude cell assembling, cell soaking and the like.

(7) The over-molded package, holds together a samarium cobalt pellet, a pole piece and a true zero-speed Hall IC that has been optimized to the magnetic circuit.

(8) There is however a gap in the magnetic circuit between the pole piece and armature so a force is created which acts to close this gap and complete the magnetic circuit.

(9) A pair of capacitative rings attached to the respective pole piece is used to detect movement of the coil.

(10) Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear and modulation distortion and increase the overload margin.

(11) The outer layer of the lithium ion battery pole roll is wrapped by a metallic foil used for preventing the outer and the side surface of the pole piece and stuck with a label.

(12) The progeny of the research can provide accordance for other pole piece production and mould design and it also can be used for the leading production directly.
