Motor identity.

Can someone help me out as to who's motor this would be. I plan on selling it but want to know what it may have been in. I do know this, it is a five pole motor with made in Japan on it. It is 24mm long 10.5mm wide and 15mm high. Got this in a collection of misc parts and motors.

Thanks, Jon

Looks like it's from an early Con-Cor/Kato loco with the horizontal split frame. The gears on both ends indicate PA or U50 with the reduction gearing, and the bend-around contact tabs are more likely to be from a PA.

Standing by for correction from the motor experts here.

Yeah, it's a second generation Con-Cor/Sekisui (Kato) PA motor. This version of the PA replaced the original version, which had a longer, squatter motor, sometime in the seventies.

Thanks guys, I knew someone here would have some idea what it was.

I'll confirm that as well.   The spur gears fit inside the cup gears in an Alco PA1.   Sekeisku?   I think that's how you spell it.

Those are first-rate five-pole motors, seriously.   I repowered my Model Power RSD15's with those back in the 80's and they are still running today, smoothly, with the same motors.   Quiet, powerful, and cool and narrow enough to fit in a hood unit.   I also did ... hmmmm.... maybe five Atlas GP7's (Roco, ones with the red plastic gears) with those motors for other friends and they are still running as well.   They wore out contacts and gears but the motors are still just fine.

At the time, that was absolutely the best five-pole motor out there and I'd still put it right up there with any Kato motor today.  Other than the fact it's not skewed, it was way ahead of its time.

Yeah, it's a second generation Con-Cor/Sekisui (Kato) PA motor....

Hmm.. and all this time
I thought it was a
Krellman Brothers
static electricity motor...
