ABSTRACT:
An ignition distributor for an internal combustion engine including a magnetic pick-up for generating a timing control voltage. The distributor has a rotor comprised of a plurality of radially extending circumferentially spaced permanent magnets that define rotor pole teeth. The permanent magnets are radially magnetized such that the outer tips all have the same magnetic polarity. As the rotor rotates, a voltage is induced in the pick-up coil by flux linking the coil that is provided by the permanent magnets. A combined electrostatic shield and flux shunt is provided that takes the form of a metallic plate of magnetic material that is located between one end of the pick-up coil and one end of the rotor.
