f 100 r.p.m. In the past, speeds as low as 30 r.p.m.were employed. Starting motors are series wound, so that it isconvenient to rate them in terms of torque rather than of horse-power. Fig. 36 shows the breakaway and running torque as afunction of the total cylinder displacement of the engine at a… … 114 DESIGN OF SMALL MOTORS 115 as well as upon its cylinder displacement, while the breakawaytorque depends merely on cylinder displacement. At usual enginespeeds, however, 200 cubic inches displacement would correspondto 20-25 hp. Low Voltages Employed. The design of the starting motor…
