What do we do with the motor wiring?
The motor came with 2 cables for each phase - 1 labeled ‘HI’ and the other labeled ‘LO’. Each of the cables if I recall correctly were 12AWG - which seems to me a little undersized for 40A, but it should be fine?
The Motor Documentation page has graphs for both ‘HIGH’ and ‘LO’ settings, so I’m trying to discover what to do here. It seems as if there might separate current paths or something to get the higher speed/torque combinations.
The documentation above and a few Youtube videos I have seen have 2 wires going into a single crimp lug for each phase:

Apparently we’ve had these Mitsuba motors running on our dyno in the past. (McMaster’s motors):

They also had both motor cables connected to the same pin on the controller.
Here’s another blog post about the Mitsuba motors:

I don’t see any labels on the cables of the motors that have both going to the same lug. I think most of the motors in the pictures are M2096D-II. I don’t know the differences between the -II and -III.
And a Master’s thesis about building a solar car (some mention of motors but the battery section was most interesting).
