Driving the BLDC motor (trapezoidal - sensorless)
This section describes how to drive the sensorless brushless permanent magnet motor. You
should first check that the board has been set-up for sensorless driving (see
Specific connection (sensor)
To also drive the motor in closed-loop mode, it is not necessary that the motor include any
position or speed sensor. For this demonstration we suggest using one Ametek BLDC
blower motor (voltage max 30 Vdc).
Specific jumper settings
Set-up the board following the instructions in
V) and
Table 14.
Set-up the board as per
LED action after power-on
Turn on the power supply. For this demonstration the power supply output voltage should be
set to 20 Vdc and the current limitation of the power supply should be set to 4 A.
After power-on, the control board LEDs should blink red, signaling that the firmware has
started to run. After a while a green LED stays on indicating an "idle" state.
Setting the potentiometers
Before running the motor, the three potentiometers P1, P2, P3 must be set (see
the correct configuration).
Running the motor (LED action)
Push the Start/Stop button. After pushing the button, the LEDs toggle from green to red to
indicate a "run" state. The motor starts to run.
