Title:
CONTROL ROD POSITION DETECTING DEVICE
Document Type and Number:
Japanese Patent JP2001208886
Kind Code:
A
Abstract:
To precisely measure the position of a control rod even if the displacement of a coupling uniting a ball screw with a driving shaft of a motor is produced.
A position detector 8 and a torque detector 29 are attached to a driving shaft 12 of a motor 10, and an arithmetical unit 30 for inputting signals of the position detector 8 and the torque detector 29 is installed. A control rod position indicating device 31 for inputting an output signal of the arithmetical unit 30 is installed. A position of a control rod 22 is detected from rotations of the driving shaft 12 of the motor 10 by the position detector 8, and corrected by the arithmetical unit 30.
