Driving the BLDC motor (trapezoidal - sensored)
This section describes how to drive the brushless permanent magnet motor with three hall
60° sensors. First you should check that the board has been set-up for BLDC 60° sensor
driving (see
Specific sensor connections
In order to be driven correctly, the motor must have three position sensors, in this case three
hall sensors. For this demonstration, we suggest using one Ametek BLDC blower motor
(voltage max 30 Vdc).
Use the connections described in
Table 17.
Specific jumper settings
Set-up the board following the instructions in
V) and
Table 18.
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.
