    I finally had a chance to open the motor up a little and found a few things worth mentioning. The HV cables going to this motor do not seem very large and it looks like it will be difficult to fit...

    I had a successful day at the local auto recycler. Picked up a used "alternator" for $80 + a $25 core charge, yeah book pricing :cool: . Less than 6,000 miles and they just cut the wires so I have a...

    Ah, I misunderstood. I thought it was some electrical black magic to simulate a higher frequency. I see your post back on page 1, that makes sense.
    Since AC Induction motors have a steep decline in...

    A couple of things to consider:

    1. With 64 pulse per revolution (1024 from the Tritium board divided by 16) the Curtis reaches it’s 10 kHz limit at 9375 RPM.

    2. This being an 8 pole motor and...

    The published 150Nm number is “engine torque”. This means it gets measured after the motor/crankshaft pulley reduction. Looking at the sizes of the pulleys I would guess it’s about a 2.5:1 reduction...

    I think you could use a digital counter on each quadrature channel as a frequency divider to bring the output in line with what the Curtis can handle.

    Something like a DM7490 can divide the number...

    That is too perfect with the Tritium board. What are the chances of just having an extra.



    Apparently, according to the developer, the little arduino can do pretty well for itself. With only...

    Max RPM of the pico-system is only 1000 and as lugnut pointed out is way too high of a resolution for the Curtis.

    I am also thinking about using this motor and wanted to keep the existing...
