The paper has designed a PWM controller for electromotor based on DSP. The DSP controller is made up of TMS320LF2407A and H-bridge. TMS320LF2407A accomplish the PWM producing, adjusting and the CAP catching of rotate speed and the showing of parameter. The H-bridge realizes the drive of the electromotor load. Comparing with traditional controller, it has the characteristic with good agility and controlled easily. The electromotor controlling based on DSP has been exercised on industry control, and has got a good effect. The paper has accomplished the need as follows mostly: Keywords: DSP;PWM;H bridge;circuit;Catch cell CAP.
