. The street railway review . s the rotor the carcan be run above synchronous speed. This combination with theinduction motor continually running makes it possible to store energywhen the car is coasting or at rest and to utilize this energy duringacceleration. It also permits of the operation of the car by com-pressed air alone for a limited period. Series Motor. The alternating current series motor, as proposed by Laninie andFinzi, made by the Westinghouse company, possesses all the char-acteristics of a direct current series motor and is directly applicableto railroad work.

The alternating current series motor, as proposed by Laninie andFinzi, made by the Westinghouse company, possesses all the char-acteristics of a direct current series motor and is directly applicableto railroad work. As shown in the accompanying illustration thecurrent passes in scries through the field and armature, the latterbeing of the drum type with commutator. .\s the direction of rota- tion in the ordinary direct current motor is not dependent on thedirection of the current, it is seen that this will operate with alternat-ing as well as with diiect current. Since the series commutatormotor cannot be operated at high voltage, it is necessary to use. mm :
