  • Publication number: 20220267250
    Abstract: A novel promotor which contains an aniline derivative is introduced. By using the promotor alone, the time and temperature of the curing reaction of the vinyl ester resin can be controlled by the unique steric effect and electronic properties of the aniline derivative. A method for preparing the above promotor is also introduced.

  • Publication number: 20220103028
    Abstract: A motor rotor plate includes a rotating shaft, a connecting portion coupled to the rotating shaft to drive the rotating shaft to rotate, and a plurality of electrode portions used to wind a coil. The electrode portions are spaced around the connecting portion at a same interval. One end of each electrode portion is coupled to the connecting portion. Another end of each electrode portion extends outward in a radial direction of the connecting portion. A width of each electrode portion gradually increases along the radial direction of the connecting portion to increase an area of the electrode portion, thereby increasing a magnetic flux, so that an electric current of the coil is reduced while maintaining a certain rotation speed to reduce heat generation.
