PMSM Motor
AlRMOVE fan's external rotor motor provides high torque for a long covering distance. The fully enclosed PMSM motor perfectly solves the problem of motor gear friction, reducing the noise level to below 43 dB(A) and making it very quiet. No gearbox, no exposed transmission parts, PMSM motor technology eliminates the need for regular maintenance, such as lubrication and gear adjustments, making the fans more reliable and cost-effective in the long run.
