Description

Technical Field

[0001] The utility model belongs to the technical field of motor shells, in particular to a high-temperature resistant modified plastic motor shell. Background Art

[0002] Plastics can be modified to improve their quality, such as density, hardness, precision, appearance, processability, transparency, mechanical properties, electromagnetic properties, chemical properties, corrosion resistance, aging resistance, wear resistance, thermal properties, flame retardancy, barrier properties and cost. Therefore, modified plastics are also used in the manufacture of motor housings. The motor housing is an important protective structure of the motor. A heat dissipation port is provided at the rear end of the motor housing. The heat generated by the motor during operation can be discharged from the housing through the heat dissipation port. However, the heat dissipation effect of the plastic motor housing is poor, which often causes the motor housing to be at a higher temperature. Once the temperature inside the housing is at a high temperature for a long time, it will seriously affect the service life of the housing and even cause the housing to deform. For this reason, the present application proposes a high-temperature resistant modified plastic motor housing. Utility Model Content
