The alternating current commutator motor, and the leakage of induction motors
Rudolf Goldschmidt's 1909 technical treatise on alternating current commutator motors and induction-motor leakage, published in London by "The Electrician" for electrical engineers and works designers. The plates mix halftone photographs of A.E.G. motor housings, armatures and stator frames against grey blocks with line-drawn sectional elevations dimensioned in millimetres, offering machined forms, laminated ribbing and numbered figure captions.
