Description


new 1PC Mal rotor axial flow fan YSWF127L50P4-840N-710 380V

Efficient cooling for motor systems with the YSWF127L50P4-840N-710 model from Mal.

This high-performance fan is designed for the PLC industry, providing efficient cooling for motor systems. It features an axial flow design, compatible with 380V, and is ideal for industrial cooling applications. The YSWF127L50P4-840N-710 model ensures reliable performance in demanding environments.

Engineer's Quick Brief

  • High-Capacity Thermal Control: Engineered explicitly as a heavy-duty 380V external rotor axial flow fan for industrial air compressor cooling packs and large-scale HVAC refrigeration condensers.
  • Optimized Aerodynamics & Form Factor: Features an integrated 710mm outer diameter assembly with a compact external rotor configuration, delivering massive static pressure while minimizing mechanical depth.
  • Dual-Speed Dual-Wiring Versatility: Supports high-efficiency Delta (Δ) and Star (Y) operational modes to fine-tune system current draw, airflow delivery, and acoustic noise constraints under variable load states.

Heavy-Duty External Rotor Axial Flow Fan

The MAER YSWF127L50P4-840N-710 is a high-performance, industrial-grade 380V AC external rotor axial flow fan designed for high-demand thermal dissipation. Utilizing a 4-pole motor design running at a rated full-load speed of 1368 RPM, this 710mm fan assembly outputs up to 1494W of electrical power at a 2.74A current threshold. Its distinctive external rotor design embeds the rotor housing directly into the axial blade hub, optimizing cooling grid layouts, ensuring smooth rotational dynamics, and providing long-term reliability within harsh industrial ventilation systems, commercial HVAC networks, and large air compressor enclosures.

Application Matrix & Industrial Use Cases

Deployment Environment Engineering Functionality System Level Payoff
Heavy Industrial Air Compressors Forces high-velocity cooling air across oil coolers and internal air-to-air heat exchangers. Suppresses continuous thermal accumulation to eliminate automatic high-temperature trip faults.
Commercial Refrigeration Condensers Draws ambient air across 710mm condenser coil matrices to expedite refrigerant phase changes. Optimizes COP efficiency curves by stabilizing compressor head discharge pressures.
Large Factory Ventilation Systems Acts as a high-volume wall or duct-mounted exhaust fan to move stagnant gases. Ensures air change compliance rates without requiring bulky external motor belt drives.

Troubleshooting & Electrical Commissioning FAQ

Q1: The axial fan operates in reverse direction upon system startup. How do I fix this?

A1: For 3-phase AC external rotor induction motors like the YSWF127L50P4, reverse rotation is resolved by isolating power and swapping any two phase input lines (e.g., swapping L1 and L2 terminals inside the junction box). This inverts the phase sequence of the stator's magnetic field, reversing physical rotation.

Q2: What causes high mechanical vibration levels across the 710mm blade housing assembly?

A2: Heavy vibrations typically trace back to dirt crust accumulations on the aluminum blades, physical warping from impact, or internal bearing wear. Ensure the blades are clean. If vibrations continue after cleaning, isolate power and test for axial/radial play in the external rotor bearings.

Q3: Is it possible to use an inverter or VFD (Variable Frequency Drive) to govern this fan's airflow speed?

A3: Yes, this external rotor motor can be driven by a VFD. However, ensure the carrier frequency is set according to the manufacturer's recommendation to prevent electrical resonance. When operating at ultra-low speeds, monitor motor skin temperature closely, as reduced airflow reduces the fan's self-cooling capability.
