Ordering information

The demonstration board is orderable through the standard ordering system, the ordering

code is: STEVAL-IHM023V2. The items delivered include the assembled demonstration

board, board documentation, PCB fabrication data such as gerber files, assembly files (pick

and place), and component documentation.

Using STEVAL-IHM023V2 with STM32 PMSM FOC

firmware library v3.0

The “STM32 PMSM FOC firmware library v3.0” is part of the STM32 PMSM single/dual

FOC SDK v3.0. In particular, it is a firmware library running on any STM32F103x and

STM32F100x device which implements the “Field Oriented Control” (FOC) drive of three-

phase “Permanent Magnet Synchronous Motors” (PMSM), both “Surface Mounted” (SM-

PMSM) and “Internal” (I-PMSM).

This section describes how to customize the firmware library by making use of the PC tool

“ST MC Workbench” (STMCWB) downloadable from www.st.com.

Environmental considerations

Warning:

The STEVAL-IHM023V2 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 shocks 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.

Note:

Isolating the application rather than the oscilloscope is highly recommended in any case.
