19. Motor Auto-calibration using the PC GUI
The full calibration of any 3-phase AC Brushless motor can be performed automatically using the PC Graphical User
Interface. Three specific buttons are now available for and shown below:
In terms of AC Brushless motor driven in sinusoidal mode and FOC algorithm, the most important parameters to
tune are:
1. Current PI parameters: Propotional Kp and Integral Ki
2. Motor parameters: Stator resistance Rs, the synchronous inductance Ls, and the Permanent Magnet flux Îm.
Letâs tune step by step a real low voltage PMSM motor using the internal power stage with Mosfets.
a) The BLAC Motor selected is the following one:
Motor type: MB057GA240
Maximum current: 3.5A
Bus Voltage: 50V
Maximum speed: 5000 RPM
Number of pole pair: 2
