Magic BAC Controller with MAC/BMC motor or Brushed motor

[August23]

if I wanted to use this controller on a brushed motor, which wires do I use?

thank you,

hello! I am trying to get a golden magic controller to work on a MAC/BMC brushless motor (internal controller is bypassed). I have not changed any of the factory settings. I believe I have the right wire combinations for the hall sensors and the phase wires. The controller does drive the motor. However, it's very weak... like its running on half power. I tried the same motor on a Lyen controller with great success. here is a pic of the inside of the motor. it's an 18 pole stator with the hall sensors placed directly inbetween the poles... and spaced by 3 poles each. Is the default Phase angle for this controller 120deg? 

while testing all 36 wire combinations I kept notes of the results. 6 of the 36 combinations resulted in CW operation and another 6 resulted in CCW rotation. My amp meter was showing 3.6amp draw for all of these wide open throttle tests (free wheel). so I retested the 6 CCW configurations (ccw necessary for my scooter) with a full load on my scooter. I found that none of the 6 combinations reached full power.... 2 of the 6 combinations gave me about 30% power. another 2 gave me about 50% power, and the last 2 gave me about 75% power. Which would lead me to believe the BMC stock hall sensor placements on this motor are wrong for this controller ... or just aren't supported. Can anyone confirm this?

Hi August,

Unfortunately, I have no idea whether the hall sensor placement on that motor is the same as the GM motors or not, but as the Lyen controllers have been used successfully on the Magic Pies, I can only assume that they should be the same.

What are you comparing the "75% power" against, the original built in controller or the Infineon?  It might just be that the GM controller does not deliver as many amps as the others. I know from other members here that the Lyen (Infineon) controller is more powerful and produces a greater top speed than the GM controller.

Apparently, the GM controller cannot be used with brushed motors, so I have no idea why there is an option to select this within the software.

Try a simple swap.  This is how the Infineon controllers hook up to a Magic Pie. If it is the same standard a Swap should be the same for either configuration.

And also the BMC MAC is a geared motor, I think, and the actual RPM inside is very high compared to GM gearless motors.  And to memory from reading Endless Sphere forums, the BMC may require a controller with a fast MCU to calculate hall signals fast enough.  Well the Mini motor is geared and OLe mayte is running a dual at 48v also, The MP has a large pole count compared to a lot of motors so it too requires a decent MCU,  to what level I do not know.  But this could explain why you may not have success if all else fails.

You might have to do some serious homework on this project.
