摘要
A TIP drive unit that calculates a cable drive torque stably is provided. In accordance with the invention, Traversing In-core Probe (TIP) drive unit includes a housing, a storage reel configured to storage the probe cable, a drive mechanism including a motor, and configured to feed the probe cable form the storage reel and spool the probe cable onto the storage reel, a motor controller configured to drive the motor at a predefined rotating speed, a processor configured to calculate a cable drive torque that is a torque necessary for moving the TIP and the probe cable by using a value of supply power necessary for driving the motor, a value of the predefined rotating speed of the motor, and a loss torque that is a torque necessary for driving the drive mechanism, and a noise filter configured to remove noise included in a signal indicating the value of the supply power.
