Abstract

Improvements introduced in a method of driving a handwheel for an electric clock, characterized by two that permanent magnets are mounted on said handwheel and a bridge circuit includes two pairs of complementary transistors connected between the positive and negative terminals of a voltage source, and a drive coil of said flywheel which is connected between the points of attachment of said pair of complementary transistors, a resistor and a capacitive element serving as a source of polarization energy connected to a base electrode of each of said complementary transistors, said drive coil being alternately supplied with the drive energy.
