1901 Emerson Repulsion Start Induction Run AC Motor

A repulsion motor is a type of electric motor which runs on alternating current (AC). It was formerly used as a traction motor for electric trains but has been superseded by other types of motors.

Repulsion motors are classified under single phase motors. In repulsion motors the stator windings are connected directly to the AC power supply and the rotor is connected to a commutator and brush assembly, similar to that of a direct current (DC) motor.video by: EPHF Museum

Edmonton Power Historical Foundation presents the Emerson 1901, one half horsepower single phase AC induction motor.This is a repulsion-start induction-run motor.


It starts as a repulsion motor and runs as an Induction motor. Until capacitors were added to the split phase stator winding, this scheme provided the starting torque needed for high starting loads.via/read more: ephf
