Description

technical field

[0001] The invention relates to a device in the technical field of micro-electro-mechanical systems, in particular to a stator-embedded electromagnetic levitation rotor micro-motor. Background technique

[0002] The use of suspension technology can avoid the friction and wear caused by contact, so as to obtain high moving speed or rotation speed, and at the same time avoid the pollution of materials due to contact, so suspension technology is widely used in production or life, such as Maglev trains, electrostatic levitation bearings, electromagnetic levitation smelting technology, electrostatic gyroscopes, etc. Electromagnetic levitation is completely a passive levitation technology, that is, it does not need an external feedback control circuit to achieve autonomous levitation. At the same time, electromagnetic levitation has no strict requirements on the gap between electrodes. Compared with electrostatic levitation, the structure of electromagnetic levitat...
