Abstract: Motor control device includes a controller controlling a motor (a calculator controller and an electric current controller), and a detector (an electric current loop) detecting an electric current of the motor and returning the detected electric current to the controller. The electric current loop includes a first detection system, a second detection system, and an electric current calculator which sums output signals from each system. Each detection system includes a sensor detecting the electric current of the motor, and a weight adjuster outputting to the electric current calculator, a detection electric current value from each sensor multiplied by a weight coefficient.

Abstract: There is provided a movement mechanism including a Z spindle the posture of which is hardly changed when the Z spindle is moved upward and downward, and having less measurement errors due to hysteresis.
A movement mechanism includes a Z-axis movement mechanism and an X-axis movement mechanism that moves the Z-axis movement mechanism in the horizontal direction. The Z-axis movement mechanism includes a Z spindle having a length in the vertical direction and a Z-axis drive unit that moves the Z spindle in the vertical direction. The Z-axis drive unit includes an open belt having an upper end fixed near an upper end portion of the Z spindle, and a lower end fixed to near a lower end portion of the Z spindle, a drive pulley around which the open belt wounded and that feeds and drives the open belt upward and downward, an upper tension roller that pushes the open belt against the Z spindle, and a lower tension roller that pushes the open belt against the Z spindle. A frame part of the X-axis movement mechanism supports the Z-axis drive unit at a position facing an X-axis guiding part by interposing the Z spindle.

Abstract: A base of a measurement apparatus in which decrease in strength can be prevented while reducing weight is achieved. A base (10) of a three-dimensional measurement apparatus (1) configured to measure a workpiece (W) with a probe (30) includes a placement unit (12) on which the workpiece (W) is placed, and a guiding unit (14) provided on a side surface (12e) side of the placement unit (12), and configured to guide a column (22) supporting the probe (30), movable in the movement direction. A guiding unit one end (14c) and a guiding unit other end (14d) of the guiding unit (14) in the movement direction extend out of a placement unit one end (12c) and a placement unit other end (12d) of the placement unit (12) in the movement direction.

Abstract: A measurement apparatus includes a probe that measures a workpiece; a moving body that moves upon receiving a driving force from a drive part while supporting the probe; a position detection part that detects a position of a moving body when the probe measures the workpiece while the moving body is moving; a displacement acquisition part that acquires an amount of displacement of the probe when the moving body moves on the basis of a detection result of a detection sensor; and a measurement value acquisition part that acquires a measurement value of the workpiece on the basis of the position of the moving body detected by the position detection part and the amount of displacement of the probe acquired by the displacement acquisition part.
