Reel-O-Matic, in Oklahoma City, OK, is a leading manufacturer of wire, cable, and flexible material
handling machines for a variety of industries including aerospace, government, oil/gas, medical,
automotive, crane, plastics, and telecommunications. Specialists in reeling, coiling, and measuring
applications, they used Yaskawa’s U1000 Industrial Matrix Drive to resolve a couple of their specific
application challenges.

CHALLENGE
Reel-O-Matic had specific application
challenges on machines with variable
speeds under heavy load and those that
required the motor to be used as a brake.
They were using either dynamic braking
packages to burn off regenerative energy
that would occur in these applications or
separate regenerative packages to put
the regenerative energy back on the grid.
Although both of these solutions reduced
the cost of operating the machines,
they required additional cost, labor, and
cabinet mounting space, while creating
a possible safety hazard, due to the
high amounts of energy being directed
to brake resistors and the resulting heat
created. They needed a more efficient
method to redirect the regenerative
energy.
SOLUTION
Yaskawa’s U1000 Industrial Matrix Drive
was introduced to Reel-O-Matic to solve
their application issues.
Unlike conventional drives, the U1000
creates a variable output by switching
directly from the input power, meaning
there is no DC bus. Regenerative energy
is put back onto the line without introducing
high levels of low frequency current
harmonics. Lower current harmonics
reduce transformer heating and allow
it operate more efficiently with an even
higher overall load.
Also, since the U1000 is a single, stand-
alone component, Reel-O-Matic was able
to eliminate extra components, reducing
cabinet size, and cost, while eliminating
potential burn or shock hazards from large
externally mounted resistors.
RESULTS
Reel-O-Matic machines are used in factory
production running 24/7. Implementing the
U1000 allows for continuous operation with no
down time due to overheating or high DC bus
conditions.
Also, lower harmonics means Reel-O-Matic
customers are inherently compliant with
the IEEE-519 standard. There will be no
need to be concerned with utility companies
complaining about elevated harmonic current
levels affecting the grid.
Max Clarke of Reel-O-Matic stated, “The
operation and benefits (of the U1000) have
been flawless for our applications.”
Increase your green space with Yaskawa’s Industrial Matrix Drive (U1000), the product that that goes beyond
conventional drives, providing outstanding harmonic performance and regeneration in a single stand-alone
component.
