Reliability, quality and
construction of the PHASE-A-MATIC™
"KW"
Rotary Phase Converter:
Baldor
Electric/PHASE-A-MATIC™ Design
.
The
rotary portion of our converter is proprietary, custom built to our
specifications by Baldor Electric, one of the largest and most
trusted motor manufacturers in the world, with warranty stations
nationwide and worldwide. It is a true phase converter and not a
modified electric motor as most of our competitors use. Many
years of testing, changing and developing the converter in
conjunction with Baldor’s engineers has produced a very simple
and trouble-free converter with extremely low idle current and low
noise level. Many of our customers confirm that our rotary
converters are the quietest and most trouble-free available.
Simplicity
of design; uses all soldered connections
.
Keeping
the design exceptionally simple reduces the risk of electrical
connection failure to almost zero since these are some of the most
common causes of failure.
We use only soldered connections with no mechanical
electrical connections like spade clips, terminals or screws which
can vibrate loose or corrode over time. There are no start
capacitors, relays or contactors with connections which can come
loose or arc and weld the contacts causing failure of the
contactor and the start capacitors, and perhaps even the rotary
converter or your equipment. Because of this we do not have
circuit board failures caused by spikes generated by the magnetic
contactors as some of our competitors do.
The
Rotor
.
The
PHASE-A-MATIC™
failure rate is practically zero because the rotors are
specifically designed and manufactured for rotary converter use.
However, some of our competitors emphasize that rotors often fail.
This is because they machine standard electric motors, modifying
and thereby weakening standard electric motor rotors, which were
not originally designed to be used as a phase converter.
Testing
before shipment
.
Every
converter is performance tested before shipment and assigned a
serial number. These records are kept for review if any questions
should ever arise about the performance specifications.
Warranty
Repairs
.
The most likely warranty repair would be bearings or windings,
which are very rare. This type of failure is much less than 1%,
and if it is going to happen at all, most likely would occur
within the first 12 months. Failures after that are extremely
rare.
See MTBF below.
MTBF
(Mean Time Between Failure)
.
Failure
rate (MTBF) is so low it's almost impossible to determine. We find
that within the first 12 months approximately 1 in 150 might
have a problem, and usually within a few weeks or months. After
the first 12 months, it might be one or less in 5,000 over a 30
year period. We continue to hear of our Rotary Converters that
have been in service for 25 or 30 years, and which are still
working flawlessly. It could go on to do another 25 or 30 years.
There is very little to go wrong with the Rotary Converter.
