| description | The invention relates to the technical field of high-speed magnetic levitation motors, in particular to a variable thrust differential pressure compensation bearing structure of an ultra-high-speed magnetic levitation motor and an axial force dynamic balance control method. The variable thrust differential pressure compensation bearing structure comprises a motor shell, a motor shaft, a main shaft seal, a main thrust bearing, a thrust disc, a thrust disc seal, an auxiliary thrust bearing, a sensor mounting piece and a displacement sensing disc; the main thrust bearing, the thrust disc seal, the auxiliary thrust bearing and the sensor installation part are sequentially installed on the motor shell from left to right, the thrust disc is installed on the motor shaft through the displacement sensing disc, the main shaft seal is installed on the main thrust bearing, and therefore the problems that in the prior art, due to material limitation, the bearing capacity of a thrust magnetic bearing is not high, and the b |
