YPT Series Low-Voltage Variable Frequency Speed Control Three-Phase Asynchronous Motor

The YPT Series low-voltage variable frequency speed-regulated motor is specifically designed for variable frequency operating conditions, accommodating wide-range frequency regulation and stepless speed adjustment requirements.

Equipped with a dual-ventilation cooling structure, it is suitable for operation across different speed ranges and serves as the core model for industrial variable frequency energy-saving retrofits.

Core Technical Parameters:

  • Voltage Rating: 380V, 660V, 380/660V, 1140V
  • Power Range: 75 kW – 560 kW
  • Pole Range: 2 – 12 poles
  • Protection Class: IP54 / IP55
  • Insulation / Temperature Rise Class: F/B, H/B (optional)
  • Duty Type: Continuous duty (S1)
  • Operating Environment: Altitude ≤ 1,000 m; Ambient temperature –15 °C to +40 °C

Cooling Method and Frequency Regulation Range:

  • Independent forced ventilation cooling (IC416): Frequency regulation range 0–60 Hz; motors with 4 poles and above can further extend the frequency regulation range, suitable for low-speed constant-torque and high-speed constant-power operating conditions.
  • Self-fan cooling (IC411): Frequency regulation range 35–60 Hz, suitable for medium-to-high-speed stable variable frequency operation scenarios.

Structural Features:

  • Both the main terminal box and the independent fan terminal box are mounted on top of the frame, supporting left and right dual-direction cable routing to accommodate various on-site wiring requirements.
  • Frame size 160 and above: Optional stator temperature monitoring device, bearing temperature monitoring device, heater, and non-stop oil injection/drainage device for long-term unattended operation.
  • Frame size 225 and above: Optional foot adjustment bolt holes can be added as required, facilitating equipment installation leveling and precision alignment.

Application Scenarios:

Various general-purpose industrial equipment requiring variable frequency speed regulation, energy conservation, consumption reduction, and precise speed control. Suitable for flexible production conditions across mining, light industry, water utilities, and other sectors.

Note: Supports customization for special voltage, special frequency regulation ranges, and custom protection classes.
