SYSTEM FOR MEASURING AND COMPENSATING MASS UNBALANCE IN A ROTATING BODY DIRECTLY DRIVEN BY A SEGVOMOTOR

摘要

PURPOSE: A weight unbalance measuring/correcting system of a rotator for driving a servo motor is provided to enable accurate correction of weight unbalance of a rotator for driving a servo motor. CONSTITUTION: A weight unbalance measuring/correcting system of a rotator for driving a servo motor comprises a sub-motor torque measuring unit(110), and a computer system(120). The sub-motor torque measuring unit measures the torque of the rotator for driving a servo motor. Based on torque characteristic data, the location deflection value the rotator for driving a servo motor and weight unbalance rate for correction are calculated using software program.
