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

There are a total of 2 barckets holding the fan on to the motor.

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

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.

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.

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.

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
