Abstract
1276135 Electric motors LICENTIA PATENT-VERWALTUNGS-GmbH 30 May 1969 [30 May 1968] 27610/69 Heading H2A A control circuit for controlling the controlled semi-conductors of an electronically commutated D.C. motor comprises devices 8, 9, 10, sequentially producing first signals representative of rotor position, a converter operating on the first signals to produce proportional and negated second signals and a logic circuit 7 producing third signals S 4 , S 5 , S 6 , for controlling the semi-conductors. Individual converters 12, 13, 14, are provided for the first signals P 1 , P 2 , P 3 , in the circuit shown. A fourth converter 15 feeds to the logic circuit proportional and negated signals of a reversing signal R. The converters are Schmidt triggers. The devices 8, 9, 10, which produce as many first signals as there are windings on the motor, may be magnetic field dependent resistances or induction coils. The logic circuit is a rectifier network, Fig. 2 (not shown), producing only one output control signal S 4 , S 5 or S 6 at a time.
