Fig. 351. -Connections for a small three-phase, squirrel-cage inductionmotor. Motors with an output of 5 h.p. or less are generallyconnected directly to the line without a starter, by means of adouble-throw switch such as that shown diagrammatically inFig. 351. This switch is so constructed that it… … Auto Transformers Fig. 352.—Connections of a starting compensator for a three-phase,squirrel-cage induction motor. Motors with an output which is greater than 5 h.p. aregenerally started up on reduced voltage by means of autotrans-formers connected as shown in Fig. 352. By this means the start-ing…
