Description
The STEVAL-IHM040V1 is a 3-phase permanent
magnet brushless motor driver designed to drive
a motor using either the six step or field oriented
control (FOC) commutation technique. The board
can operate from an AC mains of either 115 or
230 V_AC nominal at 50/60 Hz, or from a DC input
voltage between 150 and 350 VDC. The board
can supply a continuous output current of 0.5
A_RMS to the motor.
The circuit consists of three main blocks. The first
is the digital control block, which uses the
STM32F100C8T6 microcontroller to implement
the control algorithms and to generate the control
signals for the power stage. The main outputs of
the control block are the signals for the power
stage.
The second block is the power stage, a 3-phase
inverter bridge implemented using the
STGIPN3H60 SLLIMM-nano intelligent power
module. The SLLIMM includes the 6 IGBTs, gate
drivers and level shift required to interface the
logic signals from the digital control to the motor
terminals. The SLLIMM also provides a hardware
overcurrent shutdown and an op-amp used to
scale and bias the current sensing.
The third block is the power supply, which
employs the VIPER16 to convert the high voltage
DC bus to a regulated 15 V supply that supplies
the SLLIMM and analog circuitry on the board.
The 15 V supply also supplies an L78L33 linear
regulator that provides the 3.3 V logic supply for
the microcontroller.
Two firmware control programs are available, one
for six steps and one for FOC, which run on the
same hardware platform.
