After a crap week of being up ~20 hours a day doing busy work from moron college instructors, I think it's time to release some tension. The best way to do so is to have a wash party with Me, Myself, and I. My 1989 Ipso WE-165 works best for this occasion.

It gives you a work out pushing and pulling this 540LB. beast across the floor. The bed linens are dirty and need to be washed!

After loading items, still room in the cylinder.

It needs 220V AC 3 phase power 6.5 FLA, time to plug it in to the rotary phase converter. Those Elmo motors HATE phase loss!

Will try some Borax this time.

With some Plus orange box.

I thought I heard a 3 phase converter as I had one for a Hobart 60 qt. machine.

The Ipso is a rigid base machine and otherwise very dangerous to operate if not bolted to some concrete. Use this dinky whirlpool branded FL to extract the water.

Water extracted after prewash ->Yuck!

Ipso filling and splashing water every where->too much water pressure.

FS has been loaded->a bunch of it!

Is the phase converter a 220 volt AC single phase motor turning a 3 phase generator?  I saw a PCN tour about some centrifuge for the space program that had an AC motor spinning a DC generator and wondered if you had the same setup.

I think the little dinky Whirlpool just crapped out. Doesn't want to spin anymore. Have to use the Primus for extract now.

Not quite. The rotary phase converter that I built takes 220VAC 1 phase and generates 220V 3 phase. A 3 phase motor is used to do this. The motor is started by use of capacitors on legs 2 and 3. A current relay is used to change the 3rd leg of the motor to a different circuit. On this circuit, power is no longer being supplied to the third leg, but instead power is generated on this third leg by the motor. Capacitors are then placed in this circuit for cleaning up the now 3 phase supply. The capacitor induce a phase shift to get the 120 electrical degrees between legs 2 and 3. The problem is that you cannot create energy from nothing, thus one of the legs suffers because converter source does not have 3 full power legs. Because of all the capacitors used in the circuit the generated 3 phase supply from the converter has a lagging power factor. That means the voltage is ahead of the current. This is bad if you have a motor that has a heavy inertial load on it while turned off and you want to start this motor. The next step is to clean up the generated supply even more by putting a big line reactor in the circuit. The Line reactor is like an inductor, and it and be used to stablize the voltage to current ratio between the power legs. This changes the power factor of the system to leading power factor(current ahead of voltage). I also use an unloaded 440V AC 3 phase motor to clean up the supply even further. This motor filters out electrical noise, and provides more of a stable environment for the Elmo motors in the Primus and Ipso machines. Next is safety. The supply direct from the converter is sent through a fused disconnect, fused at 15A. The supply is then connected to a phase monitor to watch for single phase conditions, and phase loss conditions. I have a contactor with a thermal overload on it for excessive current draw from the machines. The contactor is controlled by the phase monitor, and shuts down the 3 phase supply circuit when the above conditions happen. What I have found is that some 3 phase motors have a wide tolerance for phase impabalance. And others have NO tolerance. The Elmo motors in the Primus and Ipso do not have very much tolerance, so the 3 phase supply going to them has to be good. My voltages are 232(1,2), 236(2,3) 230(1,3) a 3 phase Delta configuration. The 440V motor really helps out. Those Elmo motors would be quite pissed if the 440V motor were not in the circuit.

THREE PHASE POWER CONVERTER

Hi Melvin what voltage are you feeding your converter and what voltage is coming out? I would have thought that your house has 240 volt power and most 3 phase systems have 208 volts suppling the three legs.

Hi John,
The supply voltage for the rotary phase converter is usually 240V_rms from my multimeter. There are several voltage sets coming out of the phase converter. If no load is on the converter the voltages are ~ 236V_rms(measured from legs 1 and 2), 242V_rms(measured from legs 2 and 3), 251V_rms(measured from legs 1 and 3). There is a considerable amount of phase imbalance here, so I have the supply voltage pass through a line reactor rated for 82.5 FLA I believe. When the supply passes through the line reactor, the voltage is determined in part by the impedance of the load. Since both washing machines have motors in them with 2 main winding sets, to which the windings sets have different resistances and impedances, the voltage across the line reactor when under load will vary depending on what device is operating. The 440V nameplate motor is used to maintain a constant load on the line reactor , thus keeping the phase imbalance lower, and the voltage more stable. So When the Primus is in wash mode the voltages are 232V_rms(measured from legs 1 and 2), 236V_rms(measured from legs 2 and 3), 230V_rms(measured from legs 1 and 3). When in extract the voltages are 228V_rms(measured from legs 1 and 2),232V_rms(measured from legs 2 and 3), 229V_rms(measured from legs 1 and 3). I don't remember off the top of my head what the voltages are when the Ipso runs->I'll get back to you on that.

I wish the supply voltage was 208, as these two machines run a little better on it. I suppose, if I put another line reactor in series with the present one, I could achieve the 208V.

Sorry I missed your post. The phase converter is noisy because the idler motor has end bells to which the races that hold the bearings have been worn out. The result is a loose armature and shaft, which makes for extra vibration and noise. Since the motor does not have a mechanical load on it, it works for now. I will replace it eventually, new motors aren't cheap anymore. When running the Ipso, I think the fan causes it to be louder than the converter.

Now I've seen more machines of this model rated for 35LB. Time to see if this machine can live up to its rated capacity in dry weight. The pile on the floor is equivalent of 35LB. of random dirty clothes.

Post# 501982 , Reply# 20   3/6/2011 at 19:56 (4,771 days old) by supremewhirlpol ()        

Loading was random too. As in grabbing them and shoving them in the machine. This is the result and I didn't have to pack them in either.

Post# 501984 , Reply# 21   3/6/2011 at 19:59 (4,771 days old) by supremewhirlpol ()        

There are several pockets of open space. Can this machine be loaded with a 35LB load without having to pack items? Yes.

Post# 501985 , Reply# 22   3/6/2011 at 20:00 (4,771 days old) by supremewhirlpol ()        

Now lets try 40LB. This is 40LB. dry weight.

Post# 501988 , Reply# 23   3/6/2011 at 20:05 (4,771 days old) by supremewhirlpol ()        

Again random loading, no packing. This time, not as many empty space pockets. There are some here and there.

Washes very well at full capacity!

Ok John, I told you that I'd get you V_rms values when running the Ipso. Here they are. This is V_rms measuring from legs 1>2.

Post# 502000 , Reply# 26   3/6/2011 at 20:17 (4,771 days old) by supremewhirlpol ()        

V_rms value measuring legs 2>3.
