.~ Pulse-width modulated power input to motor (e.g., "duty cycle" systems)
DEFINITION
Classification: 318/599
(under subclass 580) Subject matter in which electric power
pulses of fixed magnitude and variable width are periodically applied and removed from the servo motor. The variation in width is in accordance with the servo error signal.
