ues. How is a shunt motor started? Ans. In starting a shtint motor, no trouble is likely to occurin connecting the field coils to the circuit.

The… … Figs. 739 and 740.—Multiple switch starters. Fig. 739, starter with no voltage release; fig.740, starter with no voltage release and circuit breaker. The multiple switch type ofstarter is designed to overcome the arcing on sliding contacts which, in the case of largemotors would be very severe. The…
