AXPERT-MVD
PROVIDES ULTIMATE FLEXIBILITY OF MOTOR VOLTAGE FOR
PUMPS, FANS AND SUBMERSIBLE OIL PIMPING
AXPERT-MVD has a filter. The
filter suppresses high frequency components giving a
very
close sinusoidal output waveform. The filter is a
standardized granting the user the best
quality available on the market. The AXPERT-MVD can be
used with a step-up and/or step-
down output transformer, to match any motor voltage. THE AXPERT-MVD MEDIUM VOLTAGE FREQUNCY DRIVE
CHARACTERISTICS ARE:
Ultimate flexibility in motor
voltage. The customer can choose practically any
motor voltage.
Reasonable cost. The transformer
is not over dimensioned as in drives where no
filter is used.
No extra stress on motor coil
insulations. No bearing current due to filter
and galvanic isolation
provided by the transformer.
Low motor noise. The voltage and
current waveforms are very close to sinusoidal
and therefore no
additional noise due to converter is produced.
Long cables allowed.
Can be installed in floating
networks.
Advanced control methods.
Good efficiency of the system.
FURTHER CHARACTERISTICS FOR
INDUSTRIAL PUMP AND FAN USE:
Inexpensive solution thanks to
clever filter design and inexpensive standard
output transformer.
Excellent for retrofit due to
sinusoidal output voltage.
High starting torque.
Nominal cable length up to 300
meters.
With special transformer higher
starting torque and kilometers long cables can
be applied.
FURTHER CHARACTERISTICS FOR
ELECTRICAL SUBMERSIBLE PUMP (ESP) USE:
Pump lifetime is maximized.
More than 100% starting torque by
step-up transformer.
Cables several kilometers long
may be used as there are no voltage reflections.
Long cable voltage drops needs to
be compensated by output transformer secondary
side.
NO MOTRO DERATING
A filter is provided to minimize
harmonic current flow in the motor at near seeds
and loads. Voltage
and current waveforms are near sinusoidal.
Sinusoidal voltage and current
means the motor can be used to its full rated
capacity. No thermal
de-rating is required with the AXPERT-MVD.
