MWS Series DC Brushless Motor (A Series)

The MWS (A Series) provides two drive structures—built-in and external—to meet diverse application needs. The built-in PCB adopts an aluminum alloy casting design, achieving IP54 protection, excellent heat dissipation, low temperature rise, and a long service life. For DC24V/48V models, IPX4 protection ensures reliability in wet outdoor environments.

Equipped with pulse-width control and position-sensorless technology, the motor delivers high energy efficiency (≥75%-83%) and stable long-term operation. Its stepless speed regulation (300-1300rpm) allows precise airflow adjustment, optimizing cooling performance for central air conditioner outdoor units while reducing energy consumption.

With a power range of 50W-500W and compatibility with multiple DC voltages, the series adapts to various outdoor fan sizes and system requirements. The aluminum alloy casting for built-in PCBs enhances structural durability, while the motor’s compact design fits seamlessly into standard outdoor unit enclosures, simplifying installation and replacement.

The MWS (A Series) is widely used in outdoor unit fans of commercial and residential central air conditioning systems. In high-rise office buildings, shopping malls, and hotels, its high power (180-500W) and IP54 protection efficiently drive large outdoor fans, ensuring stable heat dissipation even in harsh weather (e.g., rain, dust). For residential complexes, the DC24V/48V models (IPX4) offer quiet, energy-saving operation, reducing noise pollution and electricity costs.

Additionally, the motor’s compatibility with stepless speed regulation makes it suitable for smart HVAC systems, where airflow can be automatically adjusted based on real-time cooling demands. Its durable design and flexible drive options also make it a reliable choice for industrial ventilation fans and similar outdoor equipment, adapting to diverse environmental conditions while maintaining high performance.
