Re: Halls effect sensors...the plague from hell

"And just how big", one might ask, "are those Hall sensors that if one goes out your motor won't run?"

Well........

Re: TSDZ2, can I use an aftermarket charger?

It is important to know how many batteries and what configuration your battery pack is. Does your bms have a bluetooth setup? Is your battery configuration listed on the manufactures web site? If not, then opening the battery might be the only way to find out. A aftermarket charger that charges to t...

Re: Halls effect sensors...the plague from hell

Just the normal Honeywell SS41's Mouser, (no extra letters) they are standard enough for my specs. I just took a look at the SS41F's and had I went with them, I would have saved a couple of dollars. :roll:

Re: Halls effect sensors...the plague from hell

.... .......Equally, a 0v hall signal can be a broken wire at the controller end, so there's no pullup to 5v, and thus nothing for the hall to ground/leave open. I switched the battery, controller, and throttle to another motor and they all ran fine on the different motor. What ever it is, is proba...

Fans keep chargers cool. If you want a charger that can travel get one of these.

Re: Halls effect sensors...the plague from hell

If it stays at 5v, most likely there is a broken connection between the controller and the hall inside the motor. Usually it's just a problem at the connector contacts, but it can be a broken wire anywhere along the way. Since you've measured 5v, then the break is somewhere between that point and t...

Re: Halls effect sensors...the plague from hell

Neither did I until yesterday. After 17,000 miles on my front hub motor, it seems that I blew a hall on my front hub motor. The other two test to 0v - 5v as I spin the motor slowly backwards, but the one on the yellow wire stays at 5v the whole time.

Tie wraps? Tape? How is that going to keep the wires away from the rotor screws? Both ware out over time. Something like a hose clamp would only cut the wires over time.

Re: Homemade Battery Build question??

Sounds like a whole cell group went bad...those cells are most likely dead now.

A good bms could have stopped discharge before they discharged that low.

Dogman's advice is not hard to follow. Your motor probably only has 2 connectors attached to the short wiring leads coming out of the motor. I would suggest pinching the connectors with the thumb and a finger, and with the other hand, gently but firmly push the wires into the back of the connector. ...

I have had intermittent hall sensor problems on thumb throttles as the halls go out, but I have never had them go out on my hub motor.

Re: Fully charged Battery dies with load: Why?

Sounds like you may have more then one problem. When you say the yellow wire do you mean the yellow phase wire?

As for the battery cutting out, I am thinking that you have one or more weak cells in your battery that when put under load sags so low the bms cuts off power to the bike.
