Motor shell materials are mainly used for the winding, motor winding is often used purple copper wire or aluminum wire, which has good electrical conductivity, resistance loss IzR small.
Motor shell materials are mainly used for the winding, motor winding is often used purple copper wire or aluminum wire, which has good electrical conductivity, resistance loss IzR small.
The outer surface of the winding wire are wrapped with insulating materials, such as coated with insulating varnish film, insulating film or fiber braided tape wrapped, but also coated with epoxy resin. Due to the different levels of insulation materials, and the cooling conditions of the winding are different, and thus the permissible current density of the wire is different. The size of the cross-section of a winding wire, by the allowable current density to determine the value of the allowable current density, the design manual recommended value of the choice; using the type specification of the wire, the cross-sectional area calculated by the working conditions of the windings and the national standards selected.
Magnetically conductive materials, also known as ferromagnetic materials, motor magnetic circuit of ferromagnetic materials are mainly silicon steel sheet. The permeability of ferromagnetic material has non-linearity to the magnetic field, and irreversibility and hysteresis phenomenon in the process of magnetization; hysteresis loss and eddy current loss under the action of alternating magnetic field.
The appearance of the product is the face of the product, injection molding after the panel, chassis, after spraying, silkscreen, hot stamping and other processes, has become a major component of the electronic machine products. In order to meet the quality requirements of the whole product, plastic panels, chassis in the assembly line assembly, pay attention to the following requirements:.
( 1 ) When carrying injection molded parts by delivery truck, it should be placed in a single layer.
( 2 ) The station operator should wear gloves to prevent the injection molded parts from being stained with oil, sweat, and so on.
( 3 ) should be assembled before the panel, motor casing quality inspection, the surface should not be obvious scratches, cracks, color, surface coating Xiaxian should not blistering, cracking and peeling. After inspection, the appearance of unqualified workpieces to make a good record, isolated storage; qualified workpieces covered with flannel or plastic foam made of shroud, gently placed on the conveyor belt to the assembly line.
( 4 ) in the production line workstations, all panels, chassis contact with the work surface, should be placed on the plastic foam pad or rubber cushion, to prevent the assembly process scratches on the outer surface of the workpiece. Carrying panels, chassis should be gently held and placed, can not be touched and pressed.
( 5 ) panel, chassis and other parts of the connection assembly procedure is generally the first light and then heavy, first low and then high, first inside and then outside. The use of electric screw fastening self-tapping screws, screws and workpieces should be perpendicular to each other, can not be skewed. And the size of the torque to be appropriate, both to be able to fasten, but not too much torque caused by slippery teeth or even penetration, damage to parts. Various movable parts assembled on the panel should be operated flexibly and reliably.
