Title: Current control device of dc motor
Inventor: TOBIYO MASAHIRO
IPC: H02P7/292
Filed: 1986-10-01
Abstract: PURPOSE:To strive for more precise location and shorter positioning time required by heightening the current change rate in a low speed area. CONSTITUTION:A current limiter operates the difference between a current command value 10 and a current feedback value 11. It decides whether a speed feedback value 15 is less than the predetermined value. If the speed feedback value is more than the predetermined value, a normal gain of the current control system is multiplied to the result of the operation. If it is less than the normal gain of the predetermined value, a gain higher than the normal gain of the current control system is multiplied to the result of the operation. From this result of operation, the phase angle of a gate pulse is operated, which is given to a gate pulse generator 9. Thus, in positioning, i.e. in its low speed, it can be of a high response control system.
