Driving the BLDC Motor (trapezoidal - sensorless)
Before proceeding with the motor control demonstration, the power board STEVAL-
IHM011V1 must be set up to drive "3 Phase BLAC/DC (trapezoidal - sensorless)" settings
as described in the power board user manual.
Let's start the demonstration driving the brushless permanent magnet motor in voltage
mode - open loop - sensorless. At this point please check that the control board has been
set up for voltage mode - open loop - sensorless driving (see
BLAC/DC (trapezoidal)"
To drive the motor also in closed loop mode it is not required 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
To set up the power board jumper follow the instructions in the power board user manual for
driving the BLDC motor (trapezoidal - sensorless). Close the J5 jumper on the control board
between pin 2-3. Keep J2 of the control board open.
