| The research progress of the constant current source bias magnetic bearing is introduced. And the control scheme of a new type of constant current source bias magnetic bearing is designed. The scheme takes the TMS320F28355 DSP chip as the control core. The circuit schematic diagram of switching power amplifier and the winding structure and control principle of a new type of constant current source bias magnetic bearing are introduced in detail. Research shows that the new control scheme can improve the response speed and control precision of constant current source biased magnetic bearings, and have a good reference value. |
