Title:
DRIVE CONTROL DEVICE AND DRIVE DEVICE
Document Type and Number:
Japanese Patent JP2018147264
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manipulator 200 capable of avoiding an increase in cost by providing plural dedicated temperature sensors corresponding to each of plural speed reducers 106.SOLUTION: A manipulator 200 includes a motor 105, a speed reducer 106, and a microcomputer 210 that controls driving of the motor 105 on the basis of a result of estimation of viscous friction in the speed reducer 106 which is performed based on a temperature of a lubricant in the speed reducer 106, and a rotating speed and a driving time of the motor 105. The microcomputer 210 includes a temperature estimation unit 242 that calculates a lubricant temperature estimated value which is an estimated value of the temperature of the lubricant, and is designed to estimate the viscous friction on the basis of the lubricant temperature estimated value, the rotating speed, and the driving time.SELECTED DRAWING: Figure 4
