Digital AC servo system is widely applied
Exchange servo technology will continue to rapidly shift from the DC servo system AC servo system. From the point view of the current international market situation, almost all new products are AC servo system. AC servo motor has account for more than 80% market share in industrialized countries. More and more AC servo motor manufacturers in the domestic are gradually over manufacturers that produce DC servo motor. It can be expected that in the near future, except in certain areas outside the micro-motor, AC servo motor will completely replace the DC servo motor.
All-digital high-speed microprocessors and using the new dedicated digital signal processor (DSP) servo control unit will be fully replaced by analog electronic devices based servo motor controller unit, in order to achieve fully digital servo system.
