Ordering information

The evaluation board is available through the standard ordering system, the ordering code

is: STEVAL-IHM028V2. 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-IHM028V2 with STM32 FOC firmware

library

STM32 FOC firmware library (UM1052) is a firmware library which allows performing of the

FOC of a PMSM in configuration with and without sensors.

10.1

Environmental considerations

Warning:

The STEVAL-IHM028V2 evaluation 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.
