Control Methods for Centrifugal EC Fan (Brushless Motor + Intelligent Control)
| Aim at | Application | Control Precision | Controlled by |
| Constant Speed | Stable Load | ★★★☆☆ | 0-10V/PWM to set a constant rotation speed |
| Constant Air Flow | Filter System / Clean Room | ★★★★☆ | Feedback from air flow sensor, PID speed regulation |
| Constant Static Pressure | Long Pipe / Variable Resistance | ★★★★★ | Feedback from static pressure, real-time speed regulation |
A Customized Control Solution
- Basic Control: speed adjustable by 0-10V analog signal (coordinate with thermostat, temperature ↑→ speed ↑)
- Upgraded Control: PWM+MODBUS-RTU（monitor speed/current/temperature by PLC）
- Protection Functions: triple protections of over current/over heat/stall, with output of warning on failure
