Problems solved by technology

However, the common C-type topology transverse flux motor stator and rotor core is generally made of soft iron through machining or pressed by powder soft magnetic composite material SMC. The magnetic properties of these two materials are worse than silicon steel sheets, and soft iron The eddy current loss is high, which limits the full use of the electromagnetic performance of the transverse flux motor

Embodiment

[0022] A new type of transverse flux motor, comprising a stator disk hollow frame 3 and a number of stator pole units (such as figure 1 , 3 shown) constitutes at least one layer of annular stator poles; it also includes a rotor mother plate 8 and a number of rotor pole units (such as figure 2 , 4 shown) constitutes at least one layer of annular rotor poles.

[0023] Such as figure 1 , image 3 As shown, the stator pole unit includes a stator core fixing bolt 1 , a magnetic pole pressure plate 2 , a magnetic pole base plate 4 and a stator core 5 . One end of the magnetic pole base plate 4 is vertically fixed to the hollow base of the stator disk 3, the stator core 5 is fixed on one side of the magnetic pole base plate 4 through the stator core fixing bolt 1, and the stator cores are fixed on both sides of the magnetic pole base plate 4 5. There is also a magnetic pole clamping plate 2 between the stator core 5 and the stator core fixing bolt 1. The stator core fixing bolt...

Abstract

The invention relates to a magnetoelectric machine, in particular to a novel transverse flux motor. The transverse flux motor comprises a stator base, at least one ring-shaped stator magnetic pole composed of a plurality of stator magnetic pole units and uniformly fixed on the stator base along the circumferential direction, a rotor mother board, and at least one ring-shaped rotor magnetic pole composed of a plurality of rotor magnetic pole units and uniformly fixed on the rotor motherboard along the circumferential direction. Therefore, the transverse flux motor provided by the invention has the advantages that the defect that the stator iron core and the rotor iron core of a transverse flux motor with the conventional C-shaped topology structure cannot balance high permeability and low consumption is overcome; and besides, the structure design is flexible and simple, the assembly is easy, the utilization ratio of a magnetic conductive material is high, the economical efficiency is good, and the processing and manufacturing of the motor is convenient.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to a novel transverse flux motor. Background technique [0002] The electric propulsion system will gradually become the preferred propulsion method for ships in the future due to its strong vitality, low noise, low operating cost, and flexible layout. The volume weight of the propulsion motor is proportional to its output torque, and the ship needs a low-speed, high-torque propulsion system, and the volume weight of the propulsion motor often limits the application of electric propulsion. There is an urgent need to develop a more compact propulsion motor to meet the high torque density requirements of ships. It is generally believed that in low-speed high-torque propulsion motors, the torque density of transverse flux permanent magnet motors can reach 3-6 times that of conventional motors. There is no electromagnetic coupling relationship between the phases of the transverse flux perma...
