The motorof this machine has a simple shunt winding with a speed regulating rheostat, connected inseries. The voltage of the generator may be increased or decreased by means of thegenerator field rheostat. The differential motor of Fig. 66 has been explained in Paragraph 40. The principaladvantage of the motor generator in Fig. 66 is that it maintains a uniform speed undervariable load which results in a uniform frequency of current at the terminals of thealternator.
