Title:
REGENERATION CONTROL SYSTEM FOR A SERVO MOTOR
Document Type and Number:
WIPO Patent Application WO/1987/007790
Kind Code:
A1
Abstract:
A regeneration control system for a servo motor (9) of an automatic carrier car which is powered by a storage battery (7) and which effects regeneration control during deceleration. A feedback voltage from a tacho-generator (10) of the servo motor (9) is arithmetically operated by a torque clamp circuit (11), and the output of a speed error amplifier (2) is clamped by a signal obtained from the above operation to limit the regenerated energy to a predetermined value. Thus the instruction value is clamped during regeneration, and a regeneration current that flows through the storage battery (7) is limited.
