Hey Joseph
No, not EVen close, lol. EVery ADC 8" and 9" that
I've seen comes with pre-drilled CE plate mounting
holes (although they don't always tap them with
threads) These would appear as four sets of holes
grouped into three hole groups, each group 90 degrees
from each other, for a total of 12 holes.
The middle hole of each group is the neutral hole.
When timing a motor you always move the CE plate
opposite the motors intended rotation. If looking at
the drive shaft and you wanted to advance the motor
for CCWDE (DE stands for drive end) then you would
move it CW.
These holes are not always equal distances. The ADC
8's are opposite the ADC9's, meaning when looking at
them the CCW timing holes are about 3/4" from the
nuetral hole with the CW timing hole at less than
1/2". If you compare that to the ADC9's it's just the
reverse 1/2" for CWDE and around 3/4" for CW. FWIW
the Warp motors are set at 12.5 degrees for either
direction, which allows it to take a higher voltage
but probably looses a little Eff wise.
In general 10 degrees is a time tested advance having
been applied to many a motor brand, but this can
differ depending on what voltage and current one is
using with Wayland being at an extreem 15 degrees.
Even this is just a little (less than an inch).
I'll grab some pics of the edge of the housing to show
what I'm talking about and put it up at the site if I
can remember 8^o
Anyway it's just a little move one way or the other
with the middle hole being nuetral. If you're
planning on drilling your own then calc out 10 degrees
and tranfer punch mark where to drill 8^)
I think I may have missed some of this thread but hope
this helps. As a final note, for a fair amount of
people who are getting the small MC type modded lift
motors I'll give them a 5 and 10 degree hole placement
as many of them plan to start at a mild voltage but
then upgrade to a higher voltage when funds allow.
Hope this helps
