RS540SH motor *timing*

[WillyChang 1814]

I know time and time again everyone says 540s are "zero timed"... meaning they go just as well in both directions.

But has anyone actually sat down and looked closely??

Do this please...

1) work out where the midpoint of the 2 magnets are,

2) then - where are the brushes in relation to the magnets?

Are they really zero timed?

Lets discuss what you decipher.

[TWO STAR 0]

most people reffer to "zero timing" by looking at the endbell pin located between both terminals and expecting that it is lined up between the cans magnets.the common p2k motor has a advance of 24

degrees,when you look at the can from the endbell you can see the endbell is off set in the advanced position,& can not be changed due to its endbell shape & can shape.some manufacturers have a timing

sticker or a timing stamp on the can for adjustments.the manufacturer may have the timing set at zero but there is a internal

setting of a cetain degrees usually in the slightly advanced position.
