Title: phase angle for the goldenmotor
Post by: karma on June 26, 2008, 05:34:16 PM

anyone have a info on the phase angle for the goldenmotor? is it 120 or 50 ? ;)


cheers

Kinda new to this, what is the phase angle going to do and why would you want to changei. Is one fast or stronger? and last where id the jumper if it makes a difference

it's the relative difference of the electrical angular position of the hall sensors. if motor and controller don't match on this, the setup won't work.

hi Karma

there are 12 phases
Step ahead and reverse
Rest 6 phases 360 / 6 = 60 ° by phase
I believe

bye

DanD:

Assuming that you don't know about phase angles and hall sensors,
a more rudimentary description is that, for efficiency, you want the
electric motor coil to change direction from
pulling to pushing just a hair before the magnet reaches it.
(Much like a gas engine fires the spark plug so many degrees
before the piston reaches 'top dead center')

There is a sensor that detects when the magnet passes it,
and you can use that information to decide how long
before the magnet arrives to turn on your magnet.

The phase angle on my motor was preset perfectly before it
arrived, I don't know it they were paired at the factory or if
I just got lucky.
