STM32 MOTOR CONTROL ECOSYSTEM

ST’s STM32 MCU family offers the

performance of the industry‑standard

control or field‑oriented control (FOC)

algorithms, widely used in high‑performance

motor drives.

The STM32 PMSM FOC Software

Development Kit (STSW‑STM32100) is part

of ST’s motor control ecosystem which offers

a wide range of hardware and software

solutions for various power ranges.

The STM32 PMSM FOC SDK lets users

evaluate STM32 performance and develop

a complete application for single or multiple

3‑phase permanent‑magnet motor drive

systems (sensored or sensorless).

It includes:

•

Firmware (FW): Permanent‑magnet

synchronous motor (PMSM) FOC firmware

library

•

Graphical User Interface (GUI): ST MC

Workbench (to configure the FOC firmware

library parameters)

The P‑NUCLEO‑IHM001 Nucleo pack

is a $35 motor control kit designed

to help engineers and hobbyists

experiment with motor control in

a very short time. It contains an

STM32F3 Nucleo board preloaded

with 6‑step and FOC algorithms, a

motor‑driver expansion board based

on the STSPIN L6230 motor‑driver

IC, and a 3‑phase low voltage

brushless motor using 6‑step or

FOC algorithms preloaded on the

microcontroller. P‑NUCLEO‑IHM002

embeds P‑NUCLEO‑IHM001

and a power supply..

STM32 DIGITAL POWER ECOSYSTEM

Digital switch mode power supply (D‑SMPS) solutions (HW and FW) based on

STM32F334 product line:

•

Discovery kit (32F3348DISCOVERY): lighting and buck‑boost functions

•

Evaluation boards ‑ Digital AC/DC

•

STEVAL‑ISA147V3 (500 W): Semi bridgeless PFC + LLC and SR

•

STEVAL‑ISA172V2 (2 kW): 2‑Phase iPFC + ZVS full‑bridge, phase‑shifted and SR

STEVAL‑ISA147V3

STEVAL‑ISA172V2

Using this GUI, the user generates all the

parameter header files needed to configure

the library according to application needs

and can in real‑time monitor and change

certain variables of the algorithm.

Key features

The STM32 PMSM FOC SDK offers the

following features (among others):

•

Sensorless motor control algorithm

based on the High Frequency Injection

(HFI) method for very low or zero speed

operation

•

“Maximum torque per ampere” (MTPA)

control that optimizes the motor torque for

each load and increases efficiency

•

“Feed‑forward” control that improves

current control at high speeds

•

“Start on the fly” provides smooth drive

insertion for applications where the rotor

is already rotating (e.g. outdoor fans in air

conditioners and smoke extractors)

•

Digital PFC: Single‑stage boost topology

using the same microcontroller driving

motor with ST’s FOC algorithm

And dedicated features for easy motor

Plug’n’Spin operation:

•

“Motor Profiler” for automatic detection of

motor parameters: Electrical (Rs, Ls, and

Ke) and mechanical (J and F) to run the

motor in less than one minute

Rs

Ls

Ke

•

“One‑touch tuning” to control the motor

speed using a single knob

Plug and Spin your Motor in less than 1

minute !

•

Automatic detection of key parameters

•

Zero equipment required

•

Spin motor in less than 1 minute

•

Single parameter to tune the speed

controller

•

Wide speed range

•

Adapting to various load/inertia
