Design

Adjustable speed range is larger

At present, the market has a common 7.3M diameter and fan blade type, the speed range is usually 20-50RPM; OPTFAN is based on the powerful PMSM power output system and control technology, the stepless speed range is extended to 10-53RPM, Give you wider comfort adjustment range.

The motor drive efficiency is increased by 13.6%: The permanent magnet synchronous motor has a high power factor, so that the permanent magnet synchronous motor has a smaller current than the asynchronous motor, and the corresponding stator has a smaller copper consumption and higher efficiency. The motor efficiency of the common asynchronous motor in the market is 78%, the motor efficiency of the OPT PMSM motor is 86%, and the transmission efficiency of the whole motor is increased by 13.6%.
