[PSUBS-MAILIST] 3 phase power

[k6fee via Personal_Submersibles]

Hi Hank,
The capacitors are there to create the sudo phase shift along with the windings in the motor/converter. Turning the rotor consumes power (unless you can circumvent the laws of physics. Haha), causing the reduced power output. The solid state units don't suffer this as there is no moving rotor.

Thanks Kieth,I thought the power less was only if you did not have capacitors and just relied on the third phase from the idler motor.I will check the surplus centrethanks againHank

Hank,
I have a rotory converter on my boat. Keep in mind you will only get about 2/3 of the input power on the output as some losses are acrewed to spin the converter. Also 208 volt motors will run on 220 just a bit faster than on 208.
There are solidstate converters out there, no rotating parts and more power . Check

Hi All,I need some input on converting single phase power to 3 phase.  I am thinking about going with a rotary phase converter for the two small motors on the lathe.  I am not sure though if my 208 V motors can handle 220-240 volt power.  I need to check my power source but it will be at least 220 I am guessing.  Maybe I need to use an inverter with variable output power if that exists?Hank_______________________________________________
