Advantages of PMSM (Permanent Magnet Synchronous Motor)
Compare with the traditional HVLS fan with gear, the PMSM HVLS fan is much smarter and can be installed in smaller space, this makes it a more popular model in both industrial and commercial applications.
Talking about PMSM itself, we got lots of questions from customers asking about the advantages and disadvantages, here it comes a complete list of the advantages:
PMSM itself has high power, high efficiency, and high power factor;
PMSM has low heat generation, so the motor cooling system has a simple structure, small in size and low noise;
The system adopts a fully enclosed structure, transmission gear wear-free, no transmission gear noise, no lubrication, and no maintenance;
A large overload current is allowed by PMSM, and the reliability is significantly improved;
The entire transmission system is light in weight, the unsprung weight is lighter than the traditional axle transmission, and power is great per unit weight;
Because there is no gearbox, the bogie system can be freely designed- soft bogie, single-axle bogie, etc, so that the dynamic performance is greatly improved;
The motor can be integrally mounted on the axle to form an integral direct drive system, that is, one axle is one drive unit, no need gearbox.
