The outer‑rotor permanent‑magnet synchronous motor features a compact structure with fixed central stator and rotating outer‑ring rotor. Impellers can be directly fastened onto the rotor outer ring without couplings or transmission belts, completely eliminating transmission losses.
Boasting high integration and compact footprint for easy installation, it mostly adopts surface‑mounted permanent‑magnet structure. Equipped with EC intelligent drive, it supports 0‑10V/PWM stepless intelligent speed regulation.
The direct‑connection structure delivers low vibration, low noise and fast response, well‑suited for embedded modular installation.
Capable of stable 24‑hour continuous operation with zero routine maintenance, it fits various compact fan equipment.
Widely applied in EC axial fans, cooling towers, fan wall modules and air‑curtain devices, it serves as the core energy‑saving motor for lightweight and low‑noise HVAC ventilation equipment.
