This will be based on DSP exchange of asynchronous motor servo control system, and mainly introduces the hard- ware design of double loop-locked servo motor, hardware circuit design and mainly introduces the periphery of the circuit design of DSP device types, including rectifier and inverter circuit, braking energy circuit, the electric current detection circuit, photoelectric coding, temperature detection circuit circuit and the current protection circuit. Through the temperature detection circuit of electric current and the operation state, through real-time protection circuit of photoelectric coding can solid-axes photoelectric encoder signals, DSP will signal transformation of photoelectric encoder and decoder signal conversion relation through certain motor speed and position of the calculation. Double closed servo motor control system in the current loop velocity loop, the basis of AC motor precise control.
