The STM3210B board was used as the control unit with STM32 FOC firmware library v2.0
loaded. The flux weakening strategy with no sensors was chosen for testing. Three-shunt
resistors current sensing technique was selected. All related parameters of the motor were
included in the source code via the FOCGUI 2.0.0 application.
The duration of the tests was 45 minutes with the mentioned continuous output power
measured on the load of the motor testing stand. For correct thermal measurements of the
heatsink temperature, the assembled fan was removed together with the plastic covers.
Measured parameters, visible in
Figure 15
, were taken with the type IB100 F motor.
