  • Microangle drive system for stepping motor and microangle drive circuit therefor
    Patent number: 4755732
    Abstract: A microangle drive circuit for a stepping motor and the system therefor comprising output elements pairs of which are connected to one another in series, a sense resistance connected to the output elements in series to make a motor coil control circuit for a phase or coil, a stepping motor control circuit made for n-phases, and motor coils. These circuit and system increase accuracy in rotation and stop by dividing the rotation angles of the stepping motor into microangles.
