How does PMSM technology work?
PMSM is an electromagnetic device produced by a permanent magnet as a medium for the conversion of mechanical energy and electromagnetic energy to each other. In addition, the amazingly efficient Permanent Magnet Synchronous brushless direct drive motor on the Mammoth Industrial Series Fan delivers maximum performance when it comes to speed control accuracy, torque, density balance, low noise and greater energy efficiency.
Mammoth Fans also boast a bigger range of varying speed options. Other industrial fans that traditionally have a 7.3m blade diameter will have a speed range of 20-50 RPM. With the PMSM technology and the supreme quality of the Japanese designed controller the Mammoth Industrial Series has broadened the speed range from 5-57 RPM, which enables you to tailor the level of cooling comfort.
