    Patent number: 3962593
    Abstract: An electromagnetic impulse motor having a stator and a rotor arranged for rotation relative to the stator. Permanent magnets are mounted on either the rotor or stator, while electromagnets are mounted on the other of the rotor and stator in order to cooperate the permanent magnets. A variable speed motor actuates a timing disc to pulse the electromagnets as a function of the speed of the variable speed motor to control the speed of rotation of the rotor of the electromagnetic motor.
