Induction heating represents a valid solution for hot assembly when coupling metal parts, since it allows to compensate interference with thermal expansion and subsequent driving with definitely smaller forces: productive results are significant.
Hot assembly is particularly widespread in the field of electrical motors: for die-cast cage rotors, when detaching the aluminum from the rotor pack, improving overall motor characteristics; for rotors in general, when keying the rotation shaft; for aluminum motor housings, when inserting the stator pack with interference in its apposite seating; for fitting ball bearings in their apposite seats.
