Re: "T" winding question

It's RPM per volt that matters. If you power it and can determine its RPM with an optical tachometer or a timing light, then you can extrapolate the RPM per volt. If I were selling it, I would not let you open it up, likely damage it, and then say no thanks. He has to open it to put statorade in it...

Re: What generally causes hall failure?

Just look to see what the differences are between the two. They look very close, if not exact. Same package. Temps look to be the only difference, 25C vs -40C-150C for T(A). https://www.mouser.com/datasheet/2/187/hwsc_s_a0001295895_1-2271171.pdf https://www.mouser.com/datasheet/2/187/honeywell-sens...

I was once in a south-east Asian country, and on a whim I bought an acoustic 6-string guitar as a souvenir (hoping I would learn to play someday...I never learned to play guitar) After making my selection, they asked what label I wanted on it. I was confused until they showed me the selection. I co...

Re: What generally causes hall failure?

Most motors have cheap Chinese Hall sensors, that are not reliable for heat resistance. After you replace them with Honeywell hall sensors, they will probably last very long because in most situations the fault was not abuse and overheating, only bad luck to have had the defective ones in a batch t...

Re: What generally causes hall failure?

Since I was melting motors on purpose for a time, I cooked halls. I found a motor that got good and hot, then parked hot, would cook its halls. There is a temp spike after you stop having air rushing past the motor, so it would get all hot, work fine, then next ride the halls would not be working. ...

Re: What generally causes hall failure?

Well did you buy a genuine hall sensor from an authorized dealer like Mouser.com or did you buy from some back alley hustler on ebay where you'd really have no clue if the hall sensor was genuine, counterfeit, rebranded from a dirt cheap chip. You know counterfeits are everywhere, I even heard airl...

Would it be the heat from to much current/power? They are quite small...wonder how much heat they can actually take. If not heat then is it just internal malfunction due to quality?

The USB to serial converter can also cause problems. With a different controller, I had one that did not pull low enough to read as a zero to the controller and wouldn't talk. By adding a resistor from the TX line to ground, I was able to tweak it enough to work. Some converters may work better tha...

Depends of the frame, and location where the controller is to be mounted. I like to insulate the controller from the frame, using a sheet of rubber mat and plastic mounts on which I secure the controller with screws, nuts and washers.
