FOC 2channel with using Hercules TMS570LS12

Hiroyasu Matsubara

Hello, Could anyone tell me , if is it possible that controlling two motors by FOC(Field Oriented Control) with using Hercules TMS570LS12 ? I would like to know if the Hercules MCU could calculate FOC control logic with 2 motors. I would appriciate if anyone could reply to my question. Regards, Hiroyasu Matsubara

Hello Hiroyasu,

I have forwarded your question to one of our motor control experts. They should get back with you shortly.

Yes, it is capable of control 2 or more motors.

1. From CPU load viewpoint, here are some benchmarks, look at the 2nd and 3rd column. The Benchmark was taken when CPU runs at 80MHz and it is capable of run at 180MHz. So, the time running at maxium speed should about half of these numbers. In other words, you can treat the CPU Utilization as what you need to drive two motors.

2. From periphals viewpoint, it has two NHETs, two eQEPs, 6 eCAPs, 7 pairs of ePWMs, 2 ADC cores, it can control lots of motors.
