Problems solved by technology
No matter what kind of structure is adopted, it is all composed of multiple independent units combined along the axial direction, resulting in long axial length, low critical speed, large volume, complex control, and poor radial and axial load capacity. , the system speed and output power are low, which seriously restricts the industrial application process of maglev direct drive motors

Embodiment Construction
[0027] The principle that the present invention is based on is: the present invention provides the left side bias magnetic flux 30 to the left side direct-drive motor by the left annular permanent magnet 2 of axial magnetization, and the left side control magnetic flux 35 that the left suspension control winding 10 produces The adjustment function produces the radial levitation force that controls the two-degree-of-freedom levitation in the radial direction on the left side of the rotor; the axially magnetized right annular permanent magnet 6 provides the right bias flux 25 to the right direct drive motor, and the right levitation control winding The right control magnetic flux 37 generated by 13 acts as an adjustment function to generate the radial levitation force that controls the two-degree-of-freedom levitation in the radial direction on the right side of the rotor; The magnetic flux 32 and the left axial bias magnetic flux 31 are two parts, and the right bias magnetic flu...

The invention discloses an integrated five degrees-of-freedom magnetic suspension direct drive motor. A rotor iron core comprises an axial part and a radial part, and rotor permanent magnets are arranged at two ends of the axial part; and a stator comprises a left rotor iron core, a right motor iron core, a left annular permanent magnet, a right annular permanent magnet, a left axial control iron core, a right axial control iron core and a radial control iron core, wherein the radial control iron core is arranged between the left annular permanent magnet and the right annular permanent magnet. The integrated five degrees-of-freedom magnetic suspension direct drive motor effectively solves the disadvantages of an existing five degrees-of-freedom magnetic suspension direct drive motor, and the provided highly integrated five degrees-of-freedom magnetic suspension direct drive motor is compact in structure, simple in control, manufacturing and assembling, small in size, light in weight, short in axial length, high in critical rotating speed, high in radial tape load capacity and high in rotating speed and output power.
Description
technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a motor with compact structure, simple control, manufacture and assembly, small size, light weight, short axial length, high critical speed, high iron core utilization rate, radial and axial load Highly integrated five-degree-of-freedom magnetic levitation direct drive motor with strong capability, high system speed and high output power. Background technique [0002] The five-degree-of-freedom magnetic levitation direct drive motor uses magnetic levitation technology to generate rotational torque while also generating radial force to stabilize the rotor. It is a new type of high-performance drive system that realizes the operation without any mechanical contact between the stator and the rotor. . Since there is no mechanical friction between the stator and the rotor, the rotor of the five-degree-of-freedom magnetic levitation direct drive motor can reach a high oper...
