He has made significant contributions to the field of electrical engineering, particularly in the development of watertight brushless fan motors. With a total of 2 patents to his name, Takizawa's work showcases his innovative approach to solving engineering challenges.

Latest Patents

Takizawa's latest patents include a method of manufacturing a watertight brushless fan motor. This method involves combining a stator assembly with a stator and a circuit substrate, along with a case, a die, and an annular member. The stator assembly is mounted on the bearing supporting cylindrical section of the case. The die and annular member are fixed to the case, and an insulating resin is poured into the die to mold spaces between the plate-like section and the bearing supporting cylindrical section. This design prevents cracks in the outer surface of the molded part due to molding shrinkage or temperature changes.

Another patent focuses on the watertight brushless fan motor itself. In this design, a first pad is placed in a space between the stator and the circuit substrate, while a second pad is located between the circuit substrate and the plate-like section of the case. The insulating resin forms a molded part that encapsulates the stator and circuit substrate, effectively preventing cracks caused by environmental factors.
