TURNING CONTROL DEVICE FOR SHIP PROPULSION DEVICE

Title:

TURNING CONTROL DEVICE FOR SHIP PROPULSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/054304

Kind Code:

A1

Abstract:

[Problem] To balance the load distributed on multiple AC servomotors of an electric turning control device. [Solution] A turning control device (2) for controlling a turnable ship propulsion device has: a turn control board (7) that computes a digital motor-speed command value from a deviation between a signal from a sensor (6), which detects a turn position of the ship propulsion device, and a handle signal; and multiple AC servo amplifiers (A1, A2) that output motor-speed command values upon receiving the motor-speed command value from the turn control board in order to drive AC servomotors (M1, M2). Each amplifier reduces the motor-speed command value in accordance with the amount of load during a motoring operation of the motor, increases the motor-speed command value in accordance with the amount of load during a regenerative operation, or makes no correction if the amount of load on the motor is equal to or less than a fixed value. The loads on the multiple AC servomotors can be distributed with a uniform value.
