This 20KW water-cooled rare earth permanent magnet super-silent
diesel generator set is powered by Japanese Yanmar engine and
configured with our patented technology product--rare earth
permanent magnet generator.Compared with common rare earth
permanent magnet generator set, this generator is equipped with a
sound attenuating cabinet which greatly decreases noises. With
two-year guarantee for generator replacement, It has better
cost-performance compared with Japanese generator set. It is
industrial product rather than civilian product made by
manufacturers from general machinery industry. Our clients are
those people or fields that require quality products, high
performance and low noise.
1.Compact structure, small size, and light weight which is about
30% lighter than a common generator.
2.Complicated energy consuming devices which are parts of a common
generator, such as excitation winding, exciter and AVR voltage
regulator are not needed. Besides, the efficiency and the power
factor are 20% higher than those of a common generator.
3.It has ultra strong over load capacity and can start inductive
loads of approximate power such as UPS power source, air
conditioner and motor etc.
4.It is highly reliable, maintenance free, long life, water proof
and dust -proof with no more than 50 degree of temperature rise
when the generator is under continuous full-load run.
5.Transient voltage deviation of both shock load and sudden load
drop are less than 10%. Steady-state voltage deviation is not over
0.5. Neither line voltage harmonic distortion rate nor telephone
harmonic factor is over 2%. Please be assured of the use of
precision instruments and meters.
6.Compared with brushless motor, it has neither carbon brush that
brushless motor does not have nor complicated excitation control
unit. This makes the structure simpler and lowers the whole machine
failure rate. Besides, it has ultra strong overload capacity which
belongs to carbon brush motor.(the overload capacity of Brushless
motor is low)
7.Compared with brush motor, it has not carbon brush and has no
electric sparkle or electromagnetic disturbance under operation. It
is perfectly suitable for communication and military use.
Rare earth permanent magnet generator has the advantages of both
brush motor and brushless motor, and has unsurpassable superiority
in features and performance than both.
