What are the roles of motor housings in practical applications?
Apr 03,2024
Motor casing materials are mainly used for winding, motor winding is often used purple copper wire or aluminum wire, it 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, wrapped with insulating film or fiber braid, 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 a winding wire cross-section, by the allowable current density to determine the value of the allowable current density, the design manual recommended values in the choice; using the type of wire specifications, it is calculated from the cross-sectional area and the working conditions of the windings selected in accordance with national standards.
