A compact multidrive series from ABB offers
an array of benefits to integrators, OEMs, panel builders and
end users who are optimizing energy usage through precise
control of motors. Since drives are available both in multidrive
and single drive configurations, it is useful to define the
difference and profile the benefits that the next generation of
multidrives now provides to users.
Adjustable Speed Drives are used in any
application in which there is mechanical equipment powered by
motors; the drives provide extremely precise electrical motor
control, so that motor speeds can be ramped up and down, and
maintained, at speeds required; doing so utilizes only the
energy required, rather than having a motor run at constant
(fixed) speed and utilizing an excess of energy.
Since motors consume a majority of the energy produced,
the control of motors, based on demands of loads, increases in
importance, as energy supplies become ever more strained.
Additionally, end users of motors can realize 25-70 percent
energy savings via use of motor controllers. (Despite these
benefits, the majority of motors continue to be operated without
drives.)
Single ABB industrial drives are highly
flexible AC drives that can be customized to meet the precise
needs of a single-motor application. These units convert AC
power to DC, and then invert the DC back to an AC output to a
motor. These drives cover a wide, full range of powers and
voltages. Single industrial drives also feature a wide range of
built-in options as standard equipment. They can be installed
for most applications right out of the box; and they also can be
ordered and manufactured as a customized unit for a particular
application.
What is an ABB multidrive?
A multidrive is built from industrial
drive modules that are connected to a common DC bus bar. The
common bus bar is used to supply the drive modules with DC
power, and each module then inverts the DC to AC and powers an
individual motor.
