Abstract

1300549 Electric motors ELECTRO DYNAMIC CONSTRUCTION CO Ltd 28 Jan 1970 [29 Jan 1969] 4883/69 Heading H2A A D.C. motor supplied from a controlled rectifier bridge has a salient pole field system comprising U-shaped, laminated sections arranged around the armature 5, adjacent legs A, B of the sections forming the salient poles 2, 3 and the base portions 6 of the sections forming the yoke. Laminated interpoles 4 may be attached to the base portions and the latter may be formed separately from the legs
