Surface‑Mounted Permanent‑Magnet Synchronous Motor (SPMSM) is a high‑efficiency variable‑frequency motor specially for industrial HVAC. Permanent magnets are attached and fixed onto the rotor surface, featuring simple & compact structure, low moment of inertia and low torque ripple.
Equipped with intelligent EC drive module, it supports 0‑10V/PWM stepless intelligent speed regulation. Rotating speed can be dynamically adjusted according to load, adapting to ventilation and cooling scenarios with variable working conditions.
Adopting sinusoidal wave drive, the motor delivers low vibration, low noise and fast response, and can run stably for 24‑hour continuous operation over long periods.
It supports both inner‑rotor and outer‑rotor structural designs for integrated installation of various EC fans.
With advantages of maintenance‑free performance, low failure rate and high energy efficiency, it can connect to BA building automation and environmental monitoring systems. It is the mainstream core power motor for EC fans, fan walls and energy‑saving retrofit of HVAC equipment.
