PCT No. PCT/JP89/00083 Sec. 371 Date Sep. 11, 1989 Sec. 102(e) Date Sep. 11, 1989 PCT Filed Jan. 27, 1989 PCT Pub. No. WO89/07364 PCT Pub. Date Aug. 10, 1989.A velocity control apparatus in which velocity of a servomotor (12) is controlled by PWM-control of an inverter is so adapted that the gain (K') of an amplifier section (11) in a current loop is held constant by detecting the power supply voltage of the inverter.
