Abstract
An apparatus and related method for inductively heating a workpiece is disclosed. A first magnetic unit is rotated about a metallic workpiece utilizing a super-conducting spool, while a second magnetic unit can be utilized to generate an exterior magnetic field operable to drive the first magnetic unit.
Claims14
A method for induction heating of a workpiece, the method comprising:
- (a) rotating a first magnetic unit with at least one superconducting coil about the workpiece, wherein the first magnetic unit rotates about a rotational axis;
- and
- (b) generating a magnetic field with a second magnetic unit, wherein the magnetic field rotates about the rotational axis of the first magnetic unit and drives the first magnetic unit.
An apparatus for induction heating of a workpiece clamped in a workpiece holder, the apparatus comprising:
- a first magnetic unit having a rotational axis, the first magnetic unit including at least one superconducting coil, wherein the first magnetic unit is rotatable about the workpiece, and wherein the superconducting coil generates a magnetic field that penetrates the workpiece;
- and
- a second magnetic unit to generate a magnetic field that rotates about the rotational axis of the first magnetic unit in order to rotate the first magnetic unit about the workpiece.
