RETRO FRIDAY--Say Goodbye to Garbage!

Innovations?

But Barry I thought GE was all full of innovations, I mean, you have the commercial about my mom works for GE and makes trees dance, and GE welcomes ideas that look like a bleached cookie monster and now they have some goofy guy who talks backward with people upside down, and how can you say GE has no innovation?

I mean this sarcastic, by the way. What is it with these commercials its not like they want us to buy anything from them?

hehe

That's funny, Bob. Well at least we can say their ads have innovations!!!!

Whirlaway???

When was a series wound motor used in a Whirlaway? Or are you talking about the more modern Annaheim-built "Whirlaway's". These use a permanent magnet motor.

I've tested several of them. Not too good. I agree!!

Perhaps the toughest application I have seen for series motors is in core drills and magnetic drill presses.The motors for these tools were made by Milwaukee and Black&Decker.These motors were BEASTS!!!!They ran at 18-20A @120v.The machine had an ammeter on it to measure the motor current.I have repaired a few of these motors.They have 4 brushes in them-each brush 1" wide and communtator 2 in wide.The motor has a gearbox on it.They can take core drills to 2 ft diameter and metal drills to like 3" diameter.It was rewarding to repair one of these and test it!Watch it hog its way thru concrete!!!And 15A Bosch unversal motors on electric jackhammers.Those were cool,too!

Big Series Motors

Reminds me of the motors used in electrical cable pulling winches.

But the biggest beasts in the series motor department I ever worked with were locomotive traction motors. If you were standing on the steps of the locomotive, when only moving at a couple of miles an hour or less, you could hear the soft buzz of the brushes and commutator

Yes,those Milwaukee and B&D motors were also used for cable pullers.Loco motors-these could be connected in the traction circuit as either series or shunt wound motors-hence a compound wound motor.To start the train the motor is connected as series for max torque.Once up to speed the motor is shifted to shunt wind.Some older locos the shift was manual-kinda like in a car with manual transmission.Later as the technology evolved auto winding shift was used.Now its 3Ph AC induction motors on a VFD.Yes,have listned and watched lcos start a train-the brush whine is something!!
