Electric machine e.g. electric motor comprises external supports welded on outer side from outwards, for terminal boxes, terminal boards, earthing and/or shielding bolts

摘要

A support takes the form of a threaded welding bolt (1) with an external thread. An axially protruding spark point (4) has a front end with a flange part (3). These allow the threaded welding bolt to be welded onto the base or outer side (5) of electrical equipment. The support acts wholly or partially as a welding bush with an external thread.
