  • Control method for direct current motor
    Patent number: 4697126
    Abstract: A method of controlling a direct current motor operating in an essentially no torque, discontinuous current mode provides for delivering current pulses to the motor of alternate relative polarity so as to position the motor to rapidly respond to a command signal for torque output. A steering strategy relative to the converters supplying current to the motor prevents a current reversal if the command signal is changing in a direction which would result in increased current to the motor in the direction of the last converter conduction.
