Latest Patents
One of her latest inventions is a waterproof fan. This fan includes a rotor, a stator with a winding, and a circuit board that supplies power to the winding. The design features a resin frame with an undersurface located on one side of the rotor's rotation axis, and a housing space that opens on the opposite side to house the circuit board. A waterproofing resin portion covers the stator and closes the opening of the housing space. Additionally, the fan includes a bearing that rotatably supports the rotating shaft and a cylindrical metal bearing holder that extends along the rotation axis. The frame also has a tubular holder protection portion that separates the stator from the bearing holder.
Another notable patent is for a brushless motor stator with a fitting position determining structure for the circuit substrate. This design allows for application in various types of motors with different rotational speeds by using a single type of circuit substrate. The stator features fitting convex portions that project radially outside of a virtual circle centered on a center line. It also includes fitting concave portions formed in the inner circumferential wall surrounding a through-hole of the circuit substrate. This innovative design enables the selection of a positional relationship between hall elements and stator magnetic poles, corresponding to the speed range of the motor.
