Well I'm excited about it.
When's the test run?

Re: Controller suggestions??

So I have resolution... PV told me to open the case, pull the board, and cut a connection at a particular spot. Screenshot_20190423-222028~2-415x440.png After that the motor runs fine. I was not particularly excited to crack open a magic box I had just paid for, but he's going to send me a Bluetooth...

Re: Controller suggestions??

Yeah, no combination of phase wires made it run any better.
If this controller can't start this motor from a standstill then it's worthless to me.
I'll try spinning the motor up with a drill though just to check.
I'll let you know.

Re: Controller suggestions??

The "ignition" connector contains two small wires, one red, and one orange. The red has battery voltage on it and the orange has nothing. When I jump them together my CycleAnalyst powers up but nothing else happens. Proving beyond doubt that the red wire on the ignition connector is directly tied t...

Re: Controller suggestions??

I tried that too. No difference. Besides, as the red wire has battery voltage on it already, what would change? Um, the MCU is powered by the orange wire. So basically nothing will happen if either the orange or red "ignition" wires are not both powered by your (switched) battery voltage. Why do yo...

Because the red wire has power already and with the jumper installed it is sharing that power with the orange wire.
Adding a 48v source to an existing 48v source is pointless.
However, just to attempt to keep this moving forward, I have complied.

Re: Controller suggestions??

You can see the jumper wire on the ignition circuit. And as has been stated previously, that is 100% incorrect. You need to wire BOTH the orange and the red "ignition" wires to a (switched) 48V source. M I tried that too. No difference. Besides, as the red wire has battery voltage on it already, wh...

Re: Controller suggestions??

I know that you have an controller now, but I would like to suggest the original VESC 4.12 (12s max safe, ~$60 on ebay). It might not be able to sustain your power requirement without cooling mods though. Then there is the new Vesc six (~$250) that handles 80A continuous. The best part is that they...

Re: Controller suggestions??

Ok. Well you cleared up the mystery of the sticker then.
I have already tried spinning the motor to see if it would start but I couldn't get it going very fast with just a bare shaft.

Talon, have you ever tried unplugging your hall sensors to try it as sensorless?

IMG_20190420_213736119~2-1376x912.jpg So this is the sticker on the controller. I have to assume this is in reference to winding resistance. When I googled the specs of the Mxus 3000 it showed 4 versions with winding resistances between .07 ohms and .225 ohms. So with this motors resistance coming ...

Re: Controller suggestions??

As I said earlier today... Yes, I know the motor is good. I have run it off of a 12v radio control ESC. I did it again today too. The real question about the motors this controller has been used on is about what their phase winding resistance is. I suppose I could Google those motors and see if thei...

Re: Controller suggestions??

Out of curiosity (or desperation) does this controller care what the phase winding resistances are?
I'm not sure what motors it was intended for, but my motor has .4 ohm resistance across any two of the phase windings.
I have successfully run this motor off a 12v RC ESC before so I know it works.

Re: Controller suggestions??

I started with a Magura throttle which is a 5k ohm potentiometer. I used a voltmeter to verify that the signal voltage on the green throttle wire ran between .8v and 3.6v.

I have not done anything with the EBS wires.

Re: Controller suggestions??

Did you order the 12F dual mode controller? You need the dual mode controller to use the PV controller for a sensorless motor. I spent the extra $20 to get the PV 12F dual mode controller incase I ever smoke a Hall Sensor and need to get home 😁 Yes I did, specify sensorless but honestly I'm not sur...

Well my frustration level is growing... Nothing I have tried seems to make any difference. Still no life from this motor/controller setup.

Re: Controller suggestions??

I'm using a sensorless heinzmann PMS 80 motor.
I'll double check the ignition wiring tomorrow. I had just connected the two wires to each other with a switch instead of connecting them to a power source. The CycleAnalyst powered up when they were joined together though.

The little two wire connector labeled "ignition" I have a toggle switch on that connects the two wires together. The throttle is a direct plug ...
