Background
In real life, two-degree-of-freedom motion devices are widely seen, for example, devices such as a screw drilling machine and a screw compressor need a driving shaft to move in two degrees of freedom. The existing two-degree-of-freedom motion device mainly adopts a mode of matching a plurality of motors, and the mode has the defects of complex control method, high price of a mechanical transmission device, serious mechanical abrasion and the like. However, the drawbacks of the above-described method can be solved by a two-degree-of-freedom motor. At present, two-degree-of-freedom motors are mainly classified into an induction type, a switched reluctance type and a permanent magnet type, and compared with the induction type and the switched reluctance type, the permanent magnet type two-degree-of-freedom motor has the advantage of high power density, and the research of numerous scholars is initiated.

However, considering that the linear motion permanent magnet 12 and the rotary motion permanent magnet 7 are both positioned on the stator, the magnetic field coupling of the permanent magnets is serious, and the output characteristics of the motor are influenced; in addition, the motor is only excited by the permanent magnet, so that the risk of high-temperature irreversible demagnetization exists, and the air gap magnetic field can not be adjusted, so that the requirement of variable running environment of the motor can not be well met.
The utility model patent "integrated position detection device and method of double-stator linear rotating permanent magnet motor" with publication number CN105762991A discloses a linear rotating two-degree-of-freedom motor capable of realizing rotation, linear or spiral motion. However, considering that the outer permanent magnet and the inner permanent magnet are both fixed on the rotor, the permanent magnet field coupling of the outer permanent magnet and the inner permanent magnet is serious, and the output characteristic of the motor is influenced; in addition, the motor is only excited by the permanent magnet, so that the risk of high-temperature irreversible demagnetization exists, the magnetic field is not adjustable, and the requirement of variable running environment of the motor cannot be well met.
