Ship motor forward and reverse rotation control system and control method

Abstract

The invention discloses a ship motor forward and reverse rotation control system, which is characterized by comprising a main circuit connected with the motor and a control circuit for controlling components. One ends of three phases of windings U, V and W connected to a motor in the main circuit are provided with thermal relays; one end of a contact of a contactor a is connected with power inputends L1, L2 and L3, and the other end is connected with output ends U2, V2 and W2; the contact of a contactor b and the contact of the contactor a are connected in parallel. The control circuit comprises a motor forward operation control circuit and a motor reverse operation control circuit, and the forward operation control circuit and the reverse operation control circuit are connected in parallel. The ship motor forward and reverse rotation control system has the advantages of good stability, convenience in operation and high safety performance, the forward and reverse switching of the motor is simpler, faster, safer and more reliable, a motor wiring mode does not need to be disassembled, the time is saved, the workload of the crew is greatly reduced, the working efficiency of the crewis improved, and the device is widely applied to ships.

Description

technical field [0001] The invention relates to the field of motors, in particular to a forward and reverse control system and control method of a marine motor. Background technique [0002] The forward and reverse control of marine motors means that the staff controls the motor to run forward or reverse according to needs. At present, the control of marine motors generally adopts a one-way control method, which requires manual manual rerouting, and the operation process is complicated. , it is very inconvenient, the safety performance is low, the time required to change the running direction is long, and the work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a forward and reverse control system and control method of a marine motor, which is easy to operate, improves work efficiency, and solves the above technical problems. [0004] In order to achieve the above-mentioned technical purpose and meet the above-menti...
