miuan said:If your motor has 3 phase wires and 3 hall sensors (5 small wires), then it can be run fine by the Sabvoton.
If it only has 2 wires then it is a DC motor with mechanical commutation and can not be run on brushless controllers.
Pota said:Yes. All 3 output between 0. and 5v. So that shouldent be an issue.
I dont know about phase wires. How can that be checked?
Pota said:Should i connect the battery, usb to pc and controller when performing the test?
No i have no other controller
But will the sabvoton be able to run trapezodial motor?

You have to disconnect everything before performing the motor phase test. But when disconnecting the controller, do it one phase at a time and turn the motor by hand everytime to see if it will make the motor turn easier. That would indicate a short within the controller.
I repeat, there is nothing trapezoidal inherent to a permanent magnet motor. In fact, any motor will run more efficiently on a properly setup sine wave controller.
Alan B said:The Sabvoton has autodetect, don't try halls/phase combos, just hook up and run the detection to map the motor.
The sinewave controller makes a smoothly rotating field in the motor, instead of snapping it in 60 degree jumps. This works fine with a BLDC motor. It just operates it smoothly instead of hammering it.
Of course you can! You just won't experience the benefits of the sine controller, given that your motor's windings are constructed and oriented at an angle phi that results in a trapezoidal wave when repulsed/attracted by the magnets. No controller will ever change that. What you will gain though is more power efficiency especially at low speeds. Maybe also little battery life improvement, but that's just about it!

The Controller is a Sabvoton SSC72150.
Can the hall be changed to fix this or what?

I've tried both sin and trap on BOMA's, LightningRods small/big blocks and on AstroFlight 3220's and can't hear of feel a difference. I think you really hear/feel the difference on a hub motor the most. And yes no matter what controller you use, that won't fix the trapezoidal back EMF of the motor...if it is trapezoidal...it's going to stay trapezoidal.
Hey POTA...
Turn off the halls in your Sabvoton and unplug them from the controller. Try running the motor. Does it run smooth without the halls?

It wouldent run withouth the halls connected :S
Pota said:Ill buy these halls
Honeywell SS41
But there are many types:
SS411A
SS413A
SS495A1
SS413A
SS441A
SS41F
Since my Boma has crappy cheap halls
I bought SS411A since they have it here in Norway, will that work?
Sounds good?
