ABSTRACT:
The electronic metronome has a baton reciprocatingly driven by a pulse-drive stepper motor powered by a varying voltage source. Drive circuitry generates and applies drive pulses to the stepper motor, each drive pulse being composed of a plurality of individual pulses having a pulse width which varies in accordance with variations of the voltage source and with the selected tempo at which the baton reciprocates. The stepper motor is thus driven at a constant torque-frequency characteristic despite fluctuations in the power source voltage and the tempo of the metronome.
