DRIVE MACHINE SERVICE LIFE EVALUATION DEVICE AND DRIVE MACHINE SERVICE LIFE EVALUATION METHOD

WIPO Patent Application WO/2016/147360

A1

A drive machine service life evaluation device 100 for evaluating the service life of a drive machine 200 that has a motor 201 and a load device 202, the device 100 being provided with: an input unit 104 for receiving, as input, a service life equation used in evaluating the service life of the drive machine 200, and an operation target value of the drive machine 200; a control unit 105 for controlling the drive machine 200; and an evaluation processing unit 106 for evaluating the service life of the drive machine 200. The control unit 105 acquires an operation state quantity of the drive machine 200 on the basis of a feedback value outputted from the drive machine 200, and causes the feedback value from the drive machine 200 to follow the inputted operation target value. The evaluation processing unit 106 acquires the operation state quantity from the control unit 105, uses the operation state quantity to execute a calculation of the service life equation inputted to the input unit 104, and evaluates the service life using the result of calculation.
