XFAN's Motor - Designed for the
Future
All XFAN's products are based on its key technology -
brushless motor.  Brushless motor is a kind of motor that
does not require brushes for its commutation.  The
commutation in a brushless motor is done electronically.
 In translation, this means the motor will have a very long
life and very high efficiency.  A typical brushed motor
has efficiency of 50% to 60%.  XFAN's brushless motor
can reach to 90%!
XFAN's brushless motor
Let's look at XFAN's 16" fan for example.  This brushless fan draws 15 amps
from an alternator.  A brushed fan would have to draw about 30 amps in order
to achieve the same air flow.  Further more, XFAN's motor has current limiter
which enables the motor to not go beyond 19 amps for its startup.  In fact, the
motor would gradually speed up to its maximum RPM and that process saves
a lot of power!  A conventional brushed fan would draw a spike of 60 amps of
current for its "startup" if it is to draw 30 amps continuously.  A spike current is
not only power wasting but also would stress the electrical system of one's
vehicle.
