Problems solved by technology

However, this electric propulsion method still faces the following problems: First, generators, frequency converters and propulsion motors need to be added, which not only requires a large initial investment and low efficiency, but also greatly increases the volume and weight of the propulsion system
In addition, when the frequency converter is working, it will generate harmonics, which will interfere with the ship network

Abstract

The invention provides a magnetic coupling propulsion system and its application in ship propulsion. The magnetic coupling propulsion system includes a prime mover, a magnetic coupling governor, a propulsion motor, a control device and a propulsion mechanism. The magnetic coupling governor The output shaft is connected to the input shaft of the propulsion motor, and the windings of the rotor of the magnetic coupling governor and the windings of the propulsion motor are respectively connected to the control device. In this solution, the prime mover can run at the optimal speed and at a constant speed. Since the magnetic coupling governor can adjust the output power and torque, it can make the prime mover run at a constant speed and keep it in the optimal operating state, improving the efficiency of the prime mover. motivational efficiency. Among them, the magnetic coupling governor generates electric energy while transmitting torque, and the electric energy provides power for the propulsion motor, which improves the utilization rate of energy as a whole. Since the electric energy required by the propulsion motor is generated by the magnetic coupling governor itself, there is no connection with the ship network, and there is no problem of electromagnetic interference.

Description

technical field [0001] The invention relates to a power system, in particular to a magnetic coupling propulsion system. Background technique [0002] There are two main types of ship propulsion systems: mechanical propulsion and electric propulsion. Mechanical propulsion is a traditional propulsion method. From the successful sea trial of the steam engine ship "Claremont" designed by Fulton in 1807 to the present, mechanical propulsion has developed into a very mature technology, mainly including diesel engine propulsion, steam turbine propulsion and gas turbine propulsion. Due to the complex construction of the shafting system in the mechanical propulsion system and high alignment requirements, not only the production and processing requirements are high, but also the maintenance of the system is complex and requires a large amount of maintenance. In addition, the noise and vibration of the mechanical propulsion method is large, the efficiency is low when running at low sp...
