Background
An electric machine, commonly known as a "motor", refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as power source of electric appliance or various machines. The main function of the generator is to convert mechanical energy into electric energy, and the most common generator at present utilizes heat energy, water energy and the like to drive a generator rotor to generate electricity. In the motor, the existing motor is directly assembled in the front end cover after the stator is prepared, so that the insulativity, the stability and the safety of the motor are reduced, and the cost reduction of the motor and the safety of personnel are not facilitated.
BMC materials are acronyms for Bulk molding compounds, i.e., Bulk molding compounds. It is commonly called unsaturated polyester bulk molding compound in China. The prepreg is a material block prepared by fully mixing GF (chopped glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives. This material was first used in the 60 s of the twentieth century in the first west de and uk, and was then greatly developed in the united states and japan in the 70 s and 80 s, respectively. The BMC bulk molding compound has excellent electrical properties, mechanical properties, heat resistance, insulativity and chemical corrosion resistance, is suitable for various molding processes, and can meet the requirements of various products on the properties, so the BMC bulk molding compound is more and more popular with the users.
Bulk Molding Compounds (BMCs) are thermosetting plastics in which various inert fillers, fibrous reinforcements, catalysts, stabilizers and pigments are mixed to form a tacky "putty-like" composite for compression molding or injection molding. According to different final application fields, the prepared composite material can accurately control the size, has good flame retardance and anti-electric mark property, very high dielectric strength, corrosion resistance and pollution resistance, excellent mechanical property, low shrinkage and stable color. Bulk Molding Compounds (BMCs) are excellent in flow characteristics and insulation and flame retardancy and are well suited for a variety of applications where precise details and dimensional requirements are required.
