Title:
CONTROLLER OF DC MOTOR FOR PROPELLING SHIP
Document Type and Number:
Japanese Patent JPS609387
Kind Code:
A
Abstract:
PURPOSE:To improve the safety and maneuvering property of a ship by feeding back a deviation between the set value of a regnerative power setter and the output signal of a regenerative power detector, and a deviation between the set value of a reverse propelling power setter and the output signal of a reverse propelling power detector. CONSTITUTION:A regenerative power controller 17 and a regnerative power limiter 18 are operated to set the difference between the set value of a regnerative power setter 16 and the output signal of a regenerative power detector 15 of a feedback signal of regenerative power to zero to control the speed of a DC motor 1. Similarly, a reverse propelling power detector 20 receives the output signals of a positive current detector 10, a positive voltage detector 19 and a rotating direction detector 14 and controls the output to a reverse propelling power controller 22.
