◆Permanent magnet synchronous motor application
in pumps
Recently， permanent magnet synchronous motor is becoming more
and more popular . And this motor is also applied in pump product with its
high -efficiency 、 small- size、 low- heat、 high sensitive respondent
features.
As the renewable energy application, solar pumps is considered as the
most potential solution to mitigate food 、 energy、 water crisis in the global
.
