Embodiment

[0029] refer to figure 1 , 2 , this embodiment shows a magnetic levitation bearing servo motor for an underwater robot, including an outer rotor motor and an inner rotor motor;

[0030] The outer rotor motor includes an inner stator bearing, an inner rotor bearing, and a set of permanent magnets A arranged at both axial ends of the inner stator bearing 1. The permanent magnet A is made of NdFeB, and the magnetization direction is along the axial direction of the inner rotor bearing. Magnetization, the magnetic poles of the inner rotor bearing adopt the same polarity as the permanent magnet A at the magnetic poles of the inner stator bearing;

[0031] The inner rotor motor includes an outer stator bearing, and a set of permanent magnets B arranged at both axial ends of the outer stator bearing. The permanent magnet B is made of NdFeB, and the magnetization direction is along the axial direction of the outer rotor bearing. The outer rotor The poles of the bearings are of the s...

Abstract

The invention relates to a magnetic levitation bearing servo motor for an underwater robot, which comprises an outer rotor motor and an inner rotor motor, wherein the outer rotor motor includes an inner stator bearing, an inner rotor bearing, a set of permanent magnets A arranged at two ends of the inner stator bearing in the axial direction, the permanent magnets are made of rubidium iron boron,the magnetizing direction is along the axial direction of the inner rotor bearing , and the magnetic pole of the inner rotor bearing adopts the same polarity as the permanent magnet A at the magneticpole of the inner stator bearing; and the inner rotor motor includes an external stator bearing and a set of permanent magnets B arranged at two ends of the external stator bearing in the axial direction, the permanent magnets B are made of rubidium iron boron, the magnetizing direction is along the axial direction of the external rotor bearing, and the magnetic pole of the external rotor bearingadopts the same polarity as the permanent magnet B at the magnetic pole of the external stator bearing.

Description

technical field [0001] The invention relates to a power drive component, in particular to a power drive component for a scientific research robot. Specifically, it shows a magnetic suspension bearing servo motor for an underwater robot. Background technique [0002] When the underwater robot works underwater, because the water body is rich in oxygen, it will be harmful to the environment in the salty water environment, in the acidic environment with a low pH value or in the alkaline environment with a high pH value. The inside of the motor produces great oxidation and corrosion, and the bearings of the servo motor play key roles such as fixing, connection and transmission, and are easily oxidized and corroded. Once the bearings of the servo motor are corroded by water, the motor cannot be used. Life ends here. [0003] The existing sealing technology of the servo motor of the underwater robot cannot guarantee that the water body will not enter the motor, and during the oper...
