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 STM32F100C6T6B MCU belongs to the value line medium and

low density STM32 MCU family and was selected as the key component of the control

block.

●

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

the STGIPN3H60 small low-loss intelligent molded module which contains all the

necessary active components. Please refer to the STGIP3H60 datasheet for more

information.

●

Motor - The STEVAL-IHM036V1 demonstration board is able to properly drive any

PMSM up to 100 W of nominal power, but the FOC itself is mostly conceived for

sinusoidal shaped back-EMF.

●

Power supply block - able to work from 195 VAC to 265 VAC or corresponding DC

voltage from 275 VDC to 375 VDC. The power block is based on a buck converter with

a VIPer16 controller. It is also possible to supply the application through a J5 connector

with +15 VDC. Please refer to Figure 6 for more information on how to connect the

board to the required application.

Motor control system architecture

Of the above motor control system architecture, the STEVAL-IHM036V1 does not include

any motor itself.
