The permanent magnet direct-drive motor, designed specifically for cooling towers, is directly coupled to the fan via a coupling, replacing the traditional "induction motor + reducer (belt and pulley)" transmission system. Paired with the WD200 dedicated variable frequency drive, ECC VFD control cabinet, and iMotorLinx industrial IoT platform, the overall transmission efficiency increases from 81.0% to 93.5% under a 55kW load condition, achieving an energy-saving rate of 28.9%.
Use Cases
Cooling tower fans and circulating water cooling systems for industries including power, chemical, steel, data centers, and building HVAC.
Solve pain points
Traditional powertrains use asynchronous motors with gear reducers (belts, pulleys). The multiple intermediate stages result in low efficiency and high maintenance costs.Long-term low-load fan operation results in poor efficiency and significant energy waste.The control module is outdated and unstable, with low automation levels.Limited preventive inspections hinder accurate collection of key parameters for safe and reliable cooling tower operation, failing to meet full-lifecycle O&M requirements.Cooling towers operate in damp, wet environments, requiring high motor protection ratings and specialized cooling designs. Standard asynchronous motors lack the reliability needed for such conditions.
