Electrical machines such as electric motors and compressors. In particular, the invention relates to the setting of the air gap between he bore (72) of a stator (2) formed from a stack (73) of laminations (12) and a substantially co-axial interior cylindrical rotor (1). A method of setting the air gap by pressing the stamped, stacked stator laminations (12) to form a cylindrical bore (72) is disclosed. Whilst in the pressed condition the laminations (12) are secured to the stator frame (8). Apparatus in the form of an aligning press and a stator bore and shaft aligning device is disclosed. These pieces of apparatus include expandable collets (18, 37 and 39). |
