System architecture

A generic motor control system can be basically schematized as the arrangement of four

main blocks (see Figure 2 below).

●

Control block - its main task is to accept user commands and motor drive

configuration parameters. It provides all digital signals to implement the proper motor

driving strategy. The STM3210B-EVAL demonstration board, based on the STM32

microcontroller can be used as the control block, thanks to the motor control connector

equipped on the STEVAL-IHM025V1.

●

Power block - it is based on three-phase inverter topology. The hearth of the power

block is the STGIPL14K60 integrated intelligent power module which contains all the

necessary active components. Please refer to the STGIPL14K60 datasheets for more

information.

●

The motor - the STEVAL-IHM025V1 demonstration board is able to properly drive any

PMSM, but the FOC itself is conceived for sinusoidal-shaped back-EMF. The

demonstration board is also convenient for driving any 3- or 2-phase asynchronous

motor.

●

Power supply block - able to work from 90 VAC to 285 VAC or from 125 VDC to

400 VDC. The power block is based on a buck converter with a VIPer16 controller.

Please refer to Section 4 to properly set the jumpers according to the required

application.
