blast furnace ac servo drive system is designed to drive two servo motors of blast furnace charging equipment. it enables a tilt of furnace chute (α angle) and a change of valve disc opening angle (γ angle) for furnace burden flow regulating valve. in this way, α angle and γ angle could be adjusted to match up with β angle (rotary).
1. Speed sphere of the drive system is quite large, and the rotation speed could be controlled (0-2500r/min).
2. The system enables a fast response and small failure rate.
3. The drive system enjoys a good dynamic behavior and its time constant could arrive to 1ms. Besides that, AC servo drive system also features same stopping time and startup time.
4. The system features high positioning accuracy and repeated positioning accuracy.
