Title: Pulse width modulation method
Inventor: NAKAMOTO NOBORU
IPC: H02P25/04
Filed: 1986-01-17
Abstract: PURPOSE:To modulate a pulse width to an optimum state corresponding to a command value and rotational state of a load, by a method wherein operation result started in a prescribed counter is subtracted by output pulse of an oscillator, and the pulse width is controlled corresponding to the subtraction time. CONSTITUTION:When rotational speed of a motor 7 becomes rapid, a position detection signal G becomes much and an adder-subtractor output C becomes small. When the rotational speed of the motor 7 becomes slow, the position detection signal G becomes little and the adder-subtractor output C operated in the adder-subtractor 3 becomes large. Consequently, if the rotational speed of the motor 7 is decreased (increased) with respect to a command value, pulse width of a pulse-width modulation pulse E modulated is pulse width modulation by a down counter 4 is increased (decreased) thereby the rotational speed of the motor 7 is made constant.
