Disk Motor Module

  • 格物光学-盘式电机模组.png

    The Gewu optical disc motor adopts a flat design and uses a coreless disc motor to directly drive the load. Combined with high-precision reciprocating roller bearings and high-resolution encoders, the fully closed-loop control can achieve high-precision walking accuracy and motion positioning accuracy. It can be widely applied in the medical field, semiconductor equipment, automotive and other fields.

                                                                   Characteristic

                                                                                - Motor without cogging force

                                                                                - High thrust density

                                                                                - Compact design, achieving extremely low cross-sectional height

                                                                                - High dynamic response, non-contact disc motor direct drive

                                                                                - High precision optical linear encoder feedback

                                                                                - Excellent positioning accuracy and dynamic performance
