Something interesting pulled me into the basement the other day...

Motor back in, drain hose to outer drum needed to be removed.

 

[supremewhirlpol]

Everything on this machine is 220v, so no transformers are needed, just find an appropriate place to add the fan to the circuit. The fan will run off the same circuit used for the tumble contactor coil.

 

[supremewhirlpol]

Fan installed, sounds like a mini jet engine! These open Elmo motors also HATE phase imbalance. Some 3 phase motors have better tolerances for this and can deal with the heat, which is another reason for the high out put fan. Changes have also been made to the phase converter to support bigger 3 phase motors. A bigger line reactor has been installed to better regulate the voltages of the legs, under the load of the bigger motors. It also keeps the supply inductive. The box to hold the line reactor is being mounted on to the phase converter

The thermal-overload on the supply circuit contactor has to be upgraded as well.

[supremewhirlpol]

putting in the thermal overload, the old 4-6A is too small.

 

[supremewhirlpol]

line reactor wired, now just worry about the grounds!

 

[supremewhirlpol]

The old line reactors are disconnected and removed. Tidy the wires up a bit.

 

[supremewhirlpol]

Now to test, and check imbalances. (1-2, 2-3, 1-3) Voltages are ~239 (1-2) ~241(2-3) ~246(1-3) There is still phase imbalance, however the phase angles and voltages of the legs will become more synchronized when I run more than one 3 phase device. For me, the overall voltage of the system is still a little on the high side. The machines prefer more toward 220V, or even better toward 208V. Now it is time to add at least 2 more L20 recepticals.

The Ipso machine has developed new symptoms, that suggest the cycle timer needs to be replaced. Given the price for both a new or a used timer, I will have to find a business to rebuild it.

melvin you are an

electrical whiz!!! love the pics and your thread. very interesting to read!

glad i was able to see this machine in action today when i was up! those european front loaders mean business!

THANKS FOR POSTING ALL THE PICTURES

It was great seeing all the shots of your machine after having talked to you the other day. Can't wait to see it in action some day. I may begetting that 1967 WP Imperial Mark 12 this weekend I told you about, I will keep you posted. Keep a look out for that 3 phase extractor I am looking for Thanks John

Now it is time to add another receptical.

 

[supremewhirlpol]

Mount the box.

 

[supremewhirlpol]

Run the wire, in this case I used 14-3 solid + ground. connect the wires. Make sure they are tight.

 

[supremewhirlpol]

Tape the ends! It would very bad if ANY of the terminals touch the box while in operation.

 

[supremewhirlpol]

Well there they are.

 

[supremewhirlpol]

Wire the receptical. I could have wired the second receptical off the first one, but for possible heat issues, I wired it directly from the reactor. Lets put those big lugs to use.

 

[supremewhirlpol]

Now for testing: At this point, the second receptical will be used for running another motor. This motor will be used to help refine the 3 phase supply. The first test is with a Baldor 1/4HP TEFC motor wired for 230V 3 phase. When running the Ipso and this motor leg voltages are: 225, 242, 242. These readings are better, considering that this other motor also brings the relationship of the legs more toward 120 degrees apart. The motor in the Ipso machine no longer heats up as quickly, which is a good thing. The second test will be with a Reliance 1.5HP motor wired for 460V. I'll post results of that test in a few days.

 

[supremewhirlpol]

Yesterday, I got the Ipso in "good enough" condition for a water test. I didn't send water through the hot and cold water valves because of the "missing" soap box. This is still a high voltage situation. The only leaks that I saw were from the dump valve, and the additive hose nozzels. I removed the hoses because they are clogged with dried starch, etc. I ran a hose from the sink instead. This also allowed me to test the pressure switches, and observe for the machine behaves.

 

[supremewhirlpol]

The dump valve leaks a little, but I have never seen one that has not.

 

[supremewhirlpol]

No leaks in the front.

Splashy Splashy! The water level looks a little low for my tastes. It does take a lot of water though, and I have found out the higher the water level, the more turbulent the water. The water is significantly more turbulent in the Ipso, compared to the Primus.
