Re: How slow can you wind a motor?

the issue with low kv is the amp carrying capacity of the wire required to make the many turns.....all you are trading is the output dynamics of the motor. To compensate for less amp carrying capacity due to thin wire, voltage can be increased to bring the motor's power back up, no? 100W is same wh...

How slow can you wind a motor?

We all know winding style determines whether motor will have more torque or speed (and I have read some of the "Science, Physics, Math, & Myth" thread. What a long discussion that is :shock: ). The well know Turnigy C80100 as an example. Pretty fast spinning motor, with Kv of 130. It's noisey at hig...

Re: Controller to Motor

Do you think that is a sensorless controller? In which case you can use the throttle now and motor should spin. Else, that white connector looks like the one but the wiring diagram shows something else. Use a multimeter and see if there is a 4.3 to 5V signal between ground and red on any connectors ...

This is the type of acceleration one may expect out of this motor. :D 0 to 20MPH (and beyond) in the blink of an eye.
(apologies for the poor video, only one I found). This motor's perfect for those that want to experience Tesla P85D-like forces at take off. 8)

Re: What is wrong here?

Don't ESCs have to have their throttle curve (or max throttle position) mapped first? I'd say try turning the system on with throttle preset to 100%, then after the esc initializes (beeps a few times) ramp it down to 0... and you should hear some more beeps telling you it's set. Just a guess from th...

Re: Lyen 18 FET Controller Blown

Phase shorts cannot be detected easily because normally each phase is connected to one another on the inside of the motor. But if you're positive there's a phase short (phase wires are cut into and are touching each other), DON'T apply throttle else it's instant controller death. Stuttering when app...

Re: Hitec X2 balance charger repair: 9/14- identifying compo

Thanks for the links amberwolf. I'll check them out in detail soon. For now I checked the underside of the board and found a blown trace and down the line some type of shorted voltage regulator (my guess). I will disassemble the unit further to find the part numbers. As for the "64" components - see...

Hitec X2 balance charger repair: 9/14- identifying component

It's a dual 200W charger and I plugged in a battery backwards to port 1. It stopped working (You'd think they'd have reverse protection?!). Port 2 of the dual charger works as normal. I cracked it open. Determined to fix it. Seeing as I am able to compare the two halves, maybe it's not too difficult...

So many of us have wheelie machines, right? :mrgreen: Even with a throttle tamer and extended swing arm, my bike still tends to wheelie at take off!

Re: (solved) EB218 18FET regen stutter/not working correctly

I rebuilt my wheel and in the process also redid my cromotor wiring harness. Replaced a few hall sensors and added a temp sensor. After it was all done I mounted the wheel, started my bike up as normal (with regen wires connected this time) and spun it up to test regen. It works! :D Problem must hav...

Re: EB218 18FET regen stutter

Okay. Getting close here! I tested Cromotor with wheel off ground with regen. It stuttered. Then I put my ht3525 in a vice and spun it up a little. Regen kicked it but I didn't hear a stutter. I did measurement of hall red and black to bike frame/motor. Several ohms of resistance shown. Edit: redid ...

Re: EB218 18FET regen stutter

Ok. Still haven't tested regen with another motor or gotten video of issue but will address some of the points made above. Yea, 24S LiPo is at the wall of these FETs, as you say. But I charge my pack to 99.5V and drops down to 95V quickly. R12 mod applied, I have regen set to approximately 100V. I h...

Re: EB218 18FET regen stutter

Understood. OK, so tell me about the controller: Is it 100V or 150V rated? :) Thanks, KF 100V. The other controller that I mentioned above was a 150V model of the 24FET eb2xx. Haven't gotten chance to test out two things above but it's either linked with the eb2xx controllers or my motor/wiring.

Re: EB218 18FET regen stutter

Without knowing small details, it’s a guess. The times I’ve had stuttering performance was where the insulation frayed against the framework and was shorting in damp weather, or I had a flakey ebrake switch; check the ebrake signal line for continuity. Check the ebrake switch to be sure it is perfo...

SOLVED When I engage regen it stutters, as if it's only working on two phases or halls are going crazy. I observe my CA speed reading also goes haywire. into the 30's to 50's if I'm only doing 20 and enable regen. Speed reading is fine during all other points of operation. Everything else works wel...
