Hi everyone,
I am looking for a Williams Score Motor 14A-7806 ( 50 Hz) for my Lady Luck.
I have seen there are 2 version , 28 RPM and 32 RPM of this Motor.
How or where can I find information on how many RPMs my Lady Luck engine has?
Many thanks in advance
TL:DR I don't think there are two versions of 14A-7806.
daw6205 - Planetary Pinball (
PPS ) has parts books available online at http://www.planetarypinball.com/mm5/merchant.mvc?Screen=BOOK
The 1969 book shows 14A-7805 is a 60 cycle motor, 14A-7806 is a 50 cycle.
I -THINK- the RPM is stamped on the motor but I could be wrong about that.
Pinball Resource has the 7805 listed as 28 RPM- http://www.pbresource.com/motor.html#wmsem
However a 7806 is also listed as 28 RPM at https://www.pin-games.se/parts/motors/Motor.htm
If one were to use a 28 RPM 14A-7806 50 cycle motor and run it at 60 cycles it would run 20% faster- 33.6 RPM.
Crustyknuckle Your
Smart Set uses the 'same' score motor but if it was produced for the US it probably has a 14A-7805 and would only turn at 23.3 RPM if used at 50 cycles.

Thank you for your info,
from planetary pinball I have already consulted the Williams Parts catalog on line. In my old Motor RPM is stamped score 28
Pin games has the 7806 but all at 32 RPM. He guarantees me it works the same as mine. Now I have ordered one and will try it.
