  • PMSM Series is our newest product by own design.

  • The biggest advantage of the permanent magnet synchronous motor is that the ac power is supplied from the dc source, allowing accurate control of the motor and solving the brush lifetime problem.

  • The airfoil blade is streamlined, which are developed with the advanced technologies and the principle of aerodynamic.

  • Just with a power of 1.2kw or less, the HVLS fan are able to move a mass of air and then produce a large scale of natural wind, which leads to the double functions of ventilation and cooling.

  • Unlike a small, high-velocity fan that creates small, turbulent air streams that quickly disperse. Ifan relies on size, not speed, to move a significant amount of air, it result is a silent, non-disruptive and even distribution of 1~3m/s breezes over large spaces.
