LLY: Starter RPM

[mplteddy]

Does anyone know the RPM of an LLY/LBZ starter versus an LML one? LML starter is considerably smaller, just curious.

Thanks

Holy shit! Hey Ted

Hey Albert....ya it's been a while. I still creep tho....:roflmao:

I have no data from swapping one for the other, but I've seen no difference in cranking RPM on an LML.

 

[mplteddy]

I haven't really either, can't find any specs on the two anywhere.

Call me crazy but I think there is an audible difference in the two. And I would call the lml starter 'slower' if I had to describe the sound difference.

The only spec I could find listed the old style starter at 2.2 kw, and the new style starter at 3.5 kw.

More power/torque less rpm?

You can't just say more power/torque equals rpm. So much more involved. There is gear reduction in a starter. Just say the electric motor spins at 1200 rpm and you have gear reduction of 4:1 that will spin the output at 300 rpm but with greater torque. Just like The 3.73:1 gears in your diff will transfer more torque per engine rpm. Without knowing what the motor rpm and gear reduction is we can't say.



Sorry to be OT could not find anything more than Ferm.

Not really what I was getting at, but good info nonetheless

To add mote confusion to it, the 2.2 kw for the old and 3.5 kw for the new style numbers were from ac delco. Just looked up the numbers from REMY, and they rate the old style at 2.2 kw, but the new style starter is only 1.8 kw per there catalog. So who knows.
