HYBRID MAGNETIC-LEVITATION-BEARING MEDICAL CENTRIFUGE AND CONTROL METHOD THEREFOR

摘要

A magnetic-levitation-bearing medical centrifuge, comprising a hybrid axial magnetic-levitation supporting bearing (1), a first radial magnetic-levitation bearing (2), a second radial magnetic-levitation bearing (4), a motor (3), a centrifuge drum (5), and a driving shaft (6). The hybrid axial magnetic-levitation supporting bearing (1) is installed at the top of the driving shaft (6), the first radial magnetic-levitation bearing (2) and the second radial magnetic-levitation bearing (4) are respectively installed at upper and lower parts of the driving shaft (6), and the centrifuge drum (5) is connected to the motor (3) by means of the driving shaft (6). The centrifuge can effectively reduce frictional loss of a mechanical bearing, prolong the service life, reduce power consumption, and is simple in structure and high in controllability. A control method for the hybrid magnetic-levitation-bearing medical centrifuge.
