Abstract

The invention belongs to the technical field of electrical machine processing and discloses a shell of a small and special electrical machine. The shell is prepared from the following raw materials in parts by weight: 100-120 parts of polyphenylether resin, 40-50 parts of polyvinyl chloride, 30-40 parts of styrene-butadiene rubber, 25-30 parts of polycarbonate, 18-20 parts of polyethylene glycol terephthalate, 15-18 parts of chlorinated paraffin, 12-15 parts of glyceryl tristearate, 8-10 parts of polybenzimidazole, 8-10 parts of ethylene-octylene copolymer, 8-10 parts of silicon carbide, 5-7 parts of silicon nitride, 4-5 parts of white carbon black, 3-4 parts of talcum powder, 2-3 parts of triphenyl phosphate and 1-2 parts of antimony trioxide. The shell of the small and special electrical machine, disclosed by the invention, has the advantages of high mechanical properties, good electrical insulation properties, good flame retardance, good corrosion resistance, good heat dissipating performance and the like.

Description

technical field [0001] The invention relates to the technical field of motor processing, in particular to a micro motor housing and its application. Background technique [0002] Micro motors (small and special electrical machines) are motors with small volume and capacity, whose output power is generally below several hundred watts, and motors that require special applications, performance and environmental conditions. The full name is micro special motor, referred to as micro motor. It is often used in control systems to realize the detection, calculation, amplification, execution or conversion of electromechanical signals or energy, or for transmission of mechanical loads, and can also be used as AC and DC power supplies for equipment. The basic composition of micro motors is similar to ordinary motors, including stators, rotors, armature windings, brushes and casings, but the structure is extremely compact. Although the micro-motor is small in size, its composition is ...
