4734. MOTORS, Alternating Current, Single Phase, 60 Cycle. These General Electric A. C. Power 

 Motors are of the Repulsion Induction Type for constant speed and continuous service. They 

 are so built that they may be used on either 110 volt or 220 volt current. This type of motor 

 requires less starting current than the Split Phase Induction Type and its use is required by 

 some central power stations.

4736. MOTORS, Alternating Current, Single Phase, 60 Cycle. These General Electric A. C. Power Motors 

 are of the repulsion induction type especially adapted to loads requiring heavy starting torque 

 and have the same high operating characteristics as a D. C. Compound Motor. They are pro- 

 vided with sliding base as shown in illustration above. They can be used on either 110 or 220 

 Volt, 60 Cycle, Alternating Current.

MOTORS. Alternating and Direct Current, General Electric. The application of small power 

 notors in industrial and domestic lines has increased to such enormous extent that small 

 motors, of exceptional quality and lightness, are now available at low prices. They are series 

 wound for continuous service, and will not develop an excessive speed when the entire load is 

 thrown off. The A. C. motors operate on 110 volts 60 cycles, and will also operate on 110 volt 

 direct current. The D. C. motors will operate only on 110 volt direct current.
