Based on DSP’s powerful computing power and the 2-way event manager module peripherals, a twin-motor AC servo drive design project is put forward to replace the single motor servo drive to save the volume and the cost. This design is carried out by realizing the driver through the hardware and software and experimentizing with motor and SWAI-FA upper control system. The results show that the driver achieves the real-time control of dual-motor and the project is highly feasible and cost-effective.
