Embodiment 1

[0045] Embodiment one: single-group drive, such as Figure 5 shown.

[0046] When the deck space of the ship where the wind-assisted rotor is installed is sufficient, it is sufficient to support the installation of a larger-diameter wind-assisted rotor. In order to reduce the center of gravity of the rotor system, a space is established between the rotating drum and the internal support tower 1 to install the multi-pole stator. See Figure 1 ~ Figure 4 . Between the drum and the inner supporting tower 1 is defined a space surrounding the rotor, called the drive chamber 7 . At the upper and lower ends of the driving chamber 7, an annular slot 10 is installed between the drum and the inner supporting tower 1, the outer ring of the slot rotates with the drum, and the inner ring is fixed on the supporting tower to protect the drum. At the same time, the airtightness of the driving space is ensured, and the harm caused by the external environment to the life of the electromagnet...

Embodiment 2

[0049] Embodiment two: multi-group drive, such as Image 6 shown.

[0050] The multi-group drive is to arrange electromagnetic drive equipment at one or more positions on the top, bottom and middle of the wind booster rotor according to the actual situation. The structural form is the same as the single-group drive form, and the arrangement of the electromagnetic drive forms at both ends is shown in Figure 5 , multi-group electromagnetic drive layout see Image 6 . In addition, segmented multi-group drives and variable-section internal support tower 1 multi-group drives are within the scope of the description.

[0051] During the working process, the multi-group drive form must maintain the power regulation between the various drive chambers 7 to ensure that the phases of the multi-pole stators 5 in all drive chambers 7 are coordinated with the phases of the permanent magnets 4 on the drum, and the input power Control according to actual environmental conditions. When st...

Abstract

The invention relates to a wind-assisted rotor internal electromagnetic driving device, comprising a hull deck. The hull deck is fixedly provided with an internal support tower, the top surface of theinternal support tower is provided with a rotating shaft through a thrust bearing, the outer wall of the internal support tower is provided with an outer rotating cylinder through an electromagneticdrive assembly, and the bottom surface of the outer rotating cylinder is spaced from the hull deck and is rotated by the electromagnetic drive assembly. The wind-assisted rotor internal electromagnetic driving device has the advantages of compact and reasonable structure and convenient operation. The ingenious design is that the electromagnetic drive assembly is installed between the outer wall ofthe internal support tower and the inner wall of the outer rotating cylinder, so that the rotation of the whole rotor can be conveniently realized, the working reliability is good, the mechanical loss of the rotor during the transmission process is avoided, the energy consumption of the wind-assisted rotor is reduced, and the electric motor is integrated with the drive system to effectively savethe deck space.

Description

technical field [0001] The invention relates to the technical field of electromagnetic drive equipment, in particular to an internal electromagnetic drive equipment of a wind-assisted rotor for a shaftless transmission mode and an internal electromagnetic drive mode of the wind-assisted rotor. Background technique [0002] The history of human use of wind energy can be traced back to BC. In most cases, wind was the main way for ships to propel. Until the end of the 18th century and the beginning of the 19th century, steam ships were faster, more reliable, and independent of wind. And other advantages gradually began to replace sailing ships. However, with the potential threat of climate change, harnessing wind energy for propulsion is gaining renewed attention. In recent years, new energy technologies have been widely used in ship propulsion to reduce the EEDI of ships. Among all energy sources, wind energy is a non-polluting and infinitely renewable resource. In the appli...
