Abstract :
To realized the numerical control of three-phase bearingless induction motor, the unitary configuration of numerical control experimental system of three-phase bearingless induction motor has been designed firstly, then based on TMS320LF2407A numerical control CMOS chip of motor, the hardware control system configuration has been designed, and aiming at DSP operation and controller, high-speed photoelectricity seclusion and drive circuit, measuring and adjusting circuits for current and radial displacement, keyboard and display numerical control circuit, etc..., have been presented. The suspension control experiment results have verified the feasibility and practicability of the designed system.
