Compact 220V Single-Phase To 3-Phase Servo Drive VFD Energy-Efficient Motor Control

Designed specifically for single-phase 220V power environments, this VFD converts input into three-phase 220V/380V (model-dependent) adjustable voltage and frequency to drive three-phase servo or asynchronous motors. It enables soft starting, energy-saving speed control, and precise motion control, making it ideal for home workshops, agricultural irrigation, small-scale industrial equipment upgrades, and other applications where three-phase power is unavailable.

• Input Voltage: Single-phase 220V ±15% (some models support ±25%) to accommodate voltage fluctuations.
• Output Voltage: Three-phase 220V or 380V
• Output Frequency: 0-400Hz/650Hz (wide-range speed adjustment for high-speed motors).
• Power Range: 0.4kW-45kW (covers small to medium-sized motor applications).

• V/F Control: Simple speed regulation for constant-torque loads like fans and pumps.
• Vector Control (SVC/FVC):
  • SVC (Sensorless Vector Control): Delivers 150% torque at 0.5Hz for strong low-speed starting.
  • FVC (PG Vector Control): Provides 180% torque at 0Hz with ±0.2% speed accuracy for high-precision tasks (e.g., CNC machines).
• Speed Regulation Ratio: 1:100 (SVC) to 1:1000 (FVC) for versatile load compatibility.

• Overload Protection: 150% rated current for 60 seconds, 180% for 10 seconds (prevents tripping during transient overloads).
• Motor Protection: Safeguards against overcurrent, overvoltage, undervoltage, overheating, short circuits, and phase loss.
• Environmental Adaptability: IP20 enclosure, operating temperature range: -10°C to 50°C.

• Automatic Voltage Regulation (AVR): Stabilizes output voltage during grid fluctuations to reduce motor losses.
• Energy-Saving Mode: PID control enables constant-pressure water supply or constant-current operation, cutting energy consumption by 30%+ (e.g., in pumps).
• High Power Factor: ≥95% to minimize reactive power losses and lower electricity costs.

• Scenario: Driving three-phase woodworking lathes or engraving machines with single-phase power.
• Solution: Use a 1.5kW-2.2kW VFD to output three-phase 220V, enabling stepless speed adjustment and reducing noise/energy use.

• Scenario: Constant-pressure water supply for three-phase pumps.
• Solution: Pair a 4kW VFD with a pressure sensor for PID closed-loop control, saving water and electricity.

• Scenario: Adjusting airflow to match production demands.
• Solution: Use a 0.75kW VFD with analog input (0-10V) or a potentiometer for precise airflow control.

• Select a VFD rated ≥ 1.2x the motor's power (e.g., a 2.2kW VFD for a 1.5kW motor).
• For 380V motors, reconfigure to delta connection to match 220V output.

• Power Input: Connect single-phase 220V live (L) to L1, neutral (N) to L2, and ground to PE.
• Motor Output: Link VFD terminals U/V/W to motor terminals U1/V1/W1 (delta connection).
• Control Circuit: Use an external potentiometer or PLC for frequency adjustment.

• Base Frequency: 50Hz (standard for China).
• Acceleration Time: 10-20 seconds (extend for heavy-duty loads).
• Control Mode: Choose V/F or vector control based on load requirements.
