Latest Patents

One of Hunter's latest patents is the Flywheel-driven fastener driving tool and drive unit. This power tool features a flywheel that drives a working member, such as the driver of a fastener tool. A motor located at the rear end of the tool handle powers the flywheel, which is mounted in the tool housing at the front end of the handle. The design includes a cable secured to a drum and the working member, with a clutch that selectively couples the flywheel to the drum. This mechanism allows for the winding of the cable and forceful driving of the working member. Additionally, a return cable is wound on the driver drum against a spring bias, enabling the working member to return to its prior status when the clutch decouples the flywheel from the drum. The electronic control system operates the motor to recapture the initial speed within 500 milliseconds of any speed reduction, utilizing a phase-locked loop velocity control.

Another notable patent by Hunter is the Speed control for a universal AC/DC motor. This invention involves a series universal AC/DC motor that is regulated by switching the phase angle of an AC signal using a triac power switch. The motor control provides a phase-locked loop velocity control, where a speed command circuit generates a reference frequency corresponding to a selected motor speed. The reference frequency is compared to a feedback frequency that represents the actual motor speed, allowing for precise regulation of the motor's speed.
