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

Let’s 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
