I missed the last status report, so this will just be a big one with everything, sorry Charles. In the past two weeks, we received and assembled the spookpower and spooktroller boards, and did basic testing of them. So far, they are without any problems. Once we exercised all of the basic peripherals, like the 3 phase pwm generation, adc triggering, and UART, I ported over the janktroller code. It didn’t work for a while because the faster control loop…
This week, we worked on further tuning the medium size of the two big motors with UPMC with FOC code, which took a lot of calibration and debugging. We were convinced that we needed a backup plan in case FOC does not work out, which is why we also started writing firmware for the far more simple six step zero crossing motor control algorithm as a backup. The dyno is assembled, after a whole lot more hours in the machine…
This week, I worked on finishing more machining for our dyno, which was able to spin another motor rather successfully with a chain and another sprocket. With a ACDC rectifier and some beefy fets, we were able to get some interesting result from the output of the generator motor. We have been doing some calculations on the efficiency and power results with an oscilloscope as well. Some prelim power output puts us at 700W without the motor losing control, so…
