Welder Video- Make a three phase converter and add a welder power supply to it.

 

Make money Building converters for people.

 

Hear the difference of a motor starting on the transformer method and the rotary method.

 

Regenerative blower at 490 volts- Need to run a motor at 480, 500, or any voltage?

 

How much does it cost?  I get this question a lot.

 

Rotary lack of starting power  Torture testing the rotary.

 

Oil cooling  Cooling a transformer in oil.

 

Transformer starting power  We show the starting power of the transformer method.

 

Regenerative blower  Running the regenerative blower

 

Rotary sizing problem  What if you have a ten hp motor and a ¾ horse motor?  

 

Air compressor and vacuum cleaner We run the air compressor and vac together.

 

164 amps to start vacuum   One click of the breaker starts the vac and the start amps peak out at 164.  

 

Rotary powered by transformer   We run the rotary, but feed into the capacitor leg the voltage from the transformer.  The motor runs with a better balance and the input amps are lower.  

Check out these videos!  

 

We run an air compressor at 490 volts, we run the 10 hp vacuum cleaner, we run a ¼ motor from the same converter that powers the vacuum cleaner. We show the starting power of the transformer converter, compared to the starting power of the rotary converter. We even put a 490 volt transformer in a bucket of oil. We start the vacuum cleaner from a sixty amp breaker.  We run the vacuum cleaner and the air compressor at the same time, and start one while the other is running.  We try to show you it works.
