hi basic question as ive seen conflicting information. if i was to do a diy change of a motor myself on an fxs. is it a simple plug n play or does it need programming to the existing controller?

thanks#

The motor has to be commissioned to the controller. Dealers should be able to help with this.

would that mean it wouldn't work if it was connected or is it if not commissioned there's a chance settings could be wrong and wed damage the motor. been trying to find out wat commissioned actually does but not seen any posts mentioning

Hit up mistasam's (newzeroland) video, he has done exactly what you're after

It just means it won't work right until it's been commissioned. This is all done through the software program DVT. If you have DVT and want to take a crack at it by consulting the service manual then go for it.

The motor controller puts out 3 pulses, one each 120° of motor rotation. These three pauses need to match up exactly with where the motor wants to see them for best performance. If too far off, the motor will not run correctly (if at all).


These 3 pulses is why they call it a 3-phase motor. You can see the three thick wires coming from the top of the motor controller to the motor, the signal for each is 120° after the other and must match up to the motor.

Yes, it could overheat the motor because of the severe lack of efficiency by being way out of alignment (commission) with the motor. The wasted power will be heat instead of motor power.

Guys thank you all for the replies. Understand it now and that videos interesting, especially possibility of upgrading the power but first need to get the bike back together

I have experience with this, including letting the magic smoke out of a motor, and Don is absolutely right.  If you mis-time a motor, you can smoke it.
