System architecture

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

main blocks (see Figure 2 below).

●

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

configuration parameters and to provide all digital signals to implement the proper

motor driving strategy. The ST demonstration board based on the STM32™

microcontroller STM3210B-EVAL can be used as a control block thanks to the motor

control connector used on the board.

●

A power block - makes a power conversion from the DC bus transferring to the motor

by means of a three-phase inverter topology. The power block is based on high-voltage

(high and low-side) drivers (L6390) and power switches (STGP10NC60KD) in TO-220

packages.

●

The motor itself - the STEVAL-IHM023V2 demonstration board is able to properly

drive any PMSM, but the FOC itself is conceived for sinusoidal-shaped BEMF. The

demonstration board is also suitable for driving any three or two-phase asynchronous

motor or low-voltage BLDC motors.

●

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

400 VDC. With reconfiguration of the power stage with jumpers, the board can also be

used for low-voltage applications from 18 VDC to 35 VDC. By supplying the electronic

parts on the board through an external + 15 V connector, the board can be used for

a wide voltage range up to 400 VDC. Please refer to Section 4 for detailed settings of

the jumpers according to the required application.

Motor control system architecture

Referring to the above motor control system architecture, the STEVAL-IHM023V2 includes

the power supply and the power block hardware blocks.
