AI Technical Summary
In existing generators for small gasoline engines, the stator coils are prone to contacting the engine casing, causing short circuits.
A novel flywheel coil assembly structure is designed, wherein the flywheel design includes equidistantly spaced magnet plates and a ring frame, a wiring groove in the ring frame, and insulating material. Several spacers are provided on the end face of the ring frame, which are also made of insulating material. The flywheel design includes equidistantly spaced magnet plates and a ring frame, and inner ring plates, outer ring plates, and spacers on the end face of the ring frame, forming a reasonable wiring groove to avoid contact between the coil and the engine housing.
This technology improves power generation, enables rapid battery charging with stable voltage, and avoids contact between the coil and the engine casing, thus enhancing the reliability and safety of the device.
