information
The demonstration board is available through the standard ordering system, the ordering
code is: STEVAL-IHM028V1. The items delivered include the assembled application board,
board documentation, PCB fabrication data, such as gerber files, assembly files (pick and
place), and component documentation.

Using STEVAL-IHM028V1 with STM32 FOC firmware
library
STM32 FOC firmware library v2.0 is a firmware library running on the STM3210B-MCKIT
which allows performing of the FOC of a PMSM in configuration with and without sensors.
This section describes the modifications to be applied to the STM32 FOC firmware library
v2.0 in order to make the firmware compatible with the STEVAL-IHM028V1.
11.1 Environmental
considerations
Warning:
The STEVAL-IHM028V1 demonstration board must only be
used in a power laboratory. The voltage used in the drive
system presents a shock hazard.
The kit is not electrically isolated from the DC input. This topology is very common in motor
drives. The microprocessor is grounded by the integrated ground of the DC bus. The
microprocessor and associated circuitry are hot and MUST be isolated from user controls
and communication interfaces.
Warning:
All measuring equipment must be isolated from the main
power supply before powering up the motor drive. To use an
oscilloscope with the kit, it is safer to isolate the DC supply
AND the oscilloscope. This prevents a shock occurring as
a result of touching any SINGLE point in the circuit, but does
NOT prevent shock when touching two or more points in the
circuit.
An isolated AC power supply can be constructed using an isolation transformer and
a variable transformer. A schematic of this AC power supply can be found in the AN438
application note. (Although this application note was written for a TRIAC, the isolation
constraints still apply for switching semiconductor devices such as IGBT or MOSFET).
Note:
Isolating the application rather than the oscilloscope is highly recommended in any case.
