For long heavy starting loads,
instant reversing
or momentarily overloaded motors (laundry extractors,
paper cutters, air conditioners, hoists, lathes, Taiwanese
and Chinese motors, design "E" motors, etc.) contact
factory or refer to
APPLICATION NOTES.
Multiple motor applications: Due to the high current required to start a motor,
which can be as much as 5 to 10 times the normal running
current, the horse power of the largest motor, or the
horse power of any combination of motors started at
exactly the same time, must not exceed the "Largest
Motor" rating of the rotary converter. However, once
this motor, or combination of motors, has been started
it is possible to start additional smaller motors up
to, but not exceeding, the "Total HP Load" rating of
the converter. For example, a 3 horse power converter
could run motors totaling up to 9 horse power, providing
they are not all running heavily loaded. See
INSTALLATION.
Reliability, quality and construction
of the Phase-A-Matic™
Rotary Phase Converter:
Baldor
Electric/Phase-A-Matic™
Design
The rotary
portion of our converter is 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
Phase-A-Matic™’s 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.
