Icon i60l motor misbehaving.
 
OK I’m in a bit of a spot. My gently used Icon i60l is a lawn ornament
. I bought it used with a bad magnetic brake. It ran fine for about a month. Then, it stopped. When I select forward the cart lurches forward four times then kills the throttle response until I reset the cart. I had it towed to the local dealer who said it was the controller. A new Navitas TAC-2 later the cart doesn’t lurch but instead trods along at a snails pace. The motor leads get warm to the touch and the controller indicates fault 4-8 “Encoder A input fault”. The voltage on the encoder wiring harness is 5v,3v,3v,0v and when the x,3v,x,0v is jumped, I can see the controller indicate a change from low to high. On depressing the throttle, which ranges correctly between 0.1v - 4.9v, the fault trips because there is no change.

Finally my question. I suspect that the no change is a function of the fact that the controller expects a value that the encoder isn’t providing BECAUSE the motor isn’t functioning. Or, does the encoder actually tell the motor the range it should be operating at? In other words, do I have a bad motor, a bad sensor, both or something else?

Thanks for any help in advance.

The encoder provides feedback to the controller about the rotor position so it can spin the motor correctly. Sounds like you have a bad encoder. The encoder should be on the back of the motor and might be replaceable, if you could get them. A new motor might be easier to source.

Good luck.

Thanks for the feedback. I’ll try to scrounge the part. It has “NEOS” molded onto the encoder motor mount.

I understand my Icon is actually an LV Tong LT-A617.4+2 . Does anyone know a good parts supplier? I think the motor is actually a HUANXIN HXAC 5KW labeled as LV Tong.

Remove the electronic motor brake. Then there is a snap ring that holds a sprocket looking thing that you slide off. Then you can remove 4 Allen screws to access the encoder.

I wasn’t able to find the encoder so I replaced the 4kw motor. I seem to have found the sub component manufacturer that makes the motor. I was able to work with a gentleman directly who was more than willing to send me a replacement. It was $605 USD delivered to my door and it took about a month. It was a perfect fit and the cart is running like a champ.
