Abstract

The invention discloses a moving-magnetic magnetic suspension permanent magnet synchronous planar motor, relates to a multiphase moving-magnetic magnetic suspension permanent magnet synchronous planarmotor, and belongs to the field of motors. The problem of how to give consideration to simple structure and high locating accuracy at the same time is solved. The moving-magnetic magnetic suspensionpermanent magnet synchronous planar motor includes a stator and a rotor, and air gaps exist between the stator and the rotor; magnetic levitation supporting is conducted on the rotor by the stator, and interaction of the stator and the rotor directly covert electromagnetic energy between the stator and the rotor into two-dimension planar motion of the rotor. The moving-magnetic magnetic suspensionpermanent magnet synchronous planar motor is mainly applied to modern precision and ultra-precision machining devices of precision machining, semiconductor electronic chip producing and the like.

Description

technical field [0001] The invention relates to a multi-phase moving magnet type magnetic levitation permanent magnet synchronous planar motor, which belongs to the field of motors. Background technique [0002] Modern precision and ultra-precision processing equipment has an urgent need for high-response, high-speed, high-precision two-dimensional planar drive devices, such as precision machining, semiconductor electronic chip production, mechanical loading and unloading, manufacturing automated instruments and even robot drives. [0003] The traditional two-dimensional planar driving device is usually superimposed by two sets of linear motion conversion mechanisms driven by rotating motors. Due to the complex structure of the linear motion conversion device (usually a screw-nut mechanism), the transmission accuracy and speed are subject to certain constraints. Constraints, and there are a series of problems such as friction, backlash, deformation, etc., making it difficult...
