Abstract
An electric strapping tools and methods therefor having an electric motor with an output shaft coupled to a feed wheel, a modulator circuit coupled to a power input of the motor for controlling strap tension. A magnet is disposed on an end of the motor armature and offset from the rotation axis thereof, and a magnetic field detector is disposed near magnet to detect rotation of the armature. The motor rotates the feed wheel and vibrates a welding jaw when the shaft rotates in the same direction, and tool parameter adjustment potentiometers are isolated from abuse by the tool user by corresponding control knobs coupled thereto.
