Abstract

This standard relates to all kinds of rotating electrical machines with a horizontal shaft, and with any one of three specific types of foot mounting - i.e. machines with feet down, machines with feet up, and machines for which the bedplate is an integral part - and with mounting flange for which the shaft height in the feet down version is between 355 mm and 1000 mm and pitch circle diameter of fixing holes between 1180 and 2360 mm.
