Device for heating up machine part of electrically conductive material has rotary body driven by motor and with circumferentially spaced permanent magnet poles

摘要

The device (4) has a rotary body (7) which is driven by a motor (5) and which can be mounted in the region of the bore hole (2) which is used for the shrink-fit holding of a slightly oversized cylindrical component. The rotary body has circumferentially spaced permanent magnet poles (N, S) of alternating polarity. The rotary body fits coaxially inside the bore hole.
