From my recent seminar that we give twice a year to personnel who work at nuclear plants. This is a motor repair shop I represent in New Haven, CT.

Me being the stud I am:

Flame spraying a shaft to restore a bearing fit. It is then machined to final size.

Making a random wound coil for a submersible pump motor and winding it.

A two speed, 400 HP/1000 HP vertical circulating water pump motor, it's so big because it runs at only 225/400 RPM. It's the big green thing in the back.

A 3 HP vertical diesel generator fuel oil transfer pump motor. It came in on emergency, it's nuclear safety related and we got $21,000 to do a rewind of it, takes about 4 days.

A 250 HP pump motor that failed. You can see that two of the phases open circuited and it ran on a single phase for a while before it tripped, that's the white windings that you can see, it was running on that single phase.

Here's that submersible pump rotor on the balance machine. It has the impeller attached to it. Notice the fan cooling blades on each end of the rotor, that's what they are suppose to look like.

Here's a rotor from a 125 HP motor that got loose on the shaft (the shaft is removed in these pictures), it then slide down the shaft and the rotor came in contact with the endbells of the motor.....ouch!

Neat stuff Paul, really!

 

do you have an engineering background? (maybe i'm captain obvious) neat stuff

 

That's where I got my edumacation.....operated nuclear power plants on submarines.....I was enlisted.

Have been in the commercial nuclear power industry for the last 15 years since I got out of the Navy.

 

wow, very cool

 

Plagarism is the first rule of scholarship.
