Book excerpt: Excerpt from Single-Phase Commutator Motors A Treatise on single - phase motors is largely a treatise on the sparking problem, for a thorough knowledge of the phenomenon of commutation is of even more importance in connection with single-phase than in connection with continuous-current motors. Electrical science is particularly indebted to Messrs' Parshall and Hobart, the authors of Electric Generators, and to Prof. E. Arnold, the author of Die Gleichstrommaschine, for investigating and elucidating the problem of sparking. Whilst Messrs Parshall and Hobart have evolved a simple and eminently practical criterion for predetermining sparking, Prof. Arnold has overcome the difficulties connected with a close mathematical treatment on this difficult subject. Amongst the other investigators who have contributed to our present knowledge, the names of Thornbume Reid, Pichelmayer, Rothert, Fischer-Hinnen, Prof. G. Kapp, and Niethammer may be mentioned.
