Stator easing for a surface cooled electrical machine

Abstract

Abstract 1. Stator housing for a surface-cooled electric machine having cooling fins which are parallel to the longitudinal axis of the machine housing and to each other and having a connecting flange (6A, 7A) for a terminal box (9), which connecting flange (6A, 7A) lies between the cooling fins and has a channel (6') open towards the housing interior (1A) and the flange plane of which is at a distance from the adjacent fin edges, characterised in that with a segment-type arrangement of the cooling fins and at least one housing portion (6 or 7) arranged obliquely between two adjacent segments of fins (2, 3), said housing portion is formed along one portion of its length as a closeable planar connecting flange (6A, 7A) with the channel (6') opening towards the housing interior (1A), the width of the connecting flange (6A, 7A) being dimensioned so that it is at most equal to the width of the housing portion (6, 7), and in that, furthermore, the terminal box (9) which is formed with a wider box flange (8B) is secured to the connecting flange (6A or 7A) by way of an adaptor console (8) which is provided with connecting surfaces which are correspondingly adapted to its desired inclination in respect of the connecting flange.
