  • Induction heating device with electronic positioning control
    Patent number: 4542272
    Abstract: An induction heating apparatus particularly adapted for precisely positioning the inductor relative to the workpiece before initiating the heating process. The inductor is mounted on the end of an inductor shaft that is carried by a slide. The end of the shaft opposite the inductor is connected to a coupling that couples the shaft to a stepping motor. The slide moves the inductor into engagement with the workpiece and the stepping motor is then energized to move the inductor away from the workpiece the required amount to obtain the desired spacing.
