Board description

2.1

System architecture

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

main blocks (see Figure 2).

•

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 evaluation board, based on the STM32

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

equipped on the STEVAL-IHM028V2.

•

Power block - it is based on 3-phase inverter topology. The heart of the power block is

the STGIPS20C60 integrated intelligent power module which contains all the

necessary active components. Please refer to the STGIPS20C60 datasheet for more

information.

•

Motor - the STEVAL-IHM028V2 evaluation board is able to properly drive any PMSM,

but the FOC itself is mostly conceived for sinusoidal shaped back-EMF. The evaluation

board is also convenient for driving any 3-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 VIPer26 controller. Please

refer to Section 3 to properly set the jumpers according to the required application.

Figure 2. Motor control system architecture

Of the above motor control system architecture, the STEVAL-IHM028V2 includes the power

supply and the power block hardware blocks.
