Superior and innovative peripherals

The STM32 benefits from a dual advanced peripheral

bus (APB) architecture, one of which is a high-speed

APB (up to CPU frequency). Peripherals have been

connected on this bus to increase peripheral speed:

Motor control

The STM32 Performance line embeds timers and

ADC features that are perfectly suited to three-phase

brushless motor control. The advanced control PWM

timer offers:

■

Six outputs

■

Dead-time generation

■

Edge-aligned and center-aligned waveforms

■

Emergency stop and synchronization capability

with the dual ADC, synchronization capability with

other timers

■

Programmable smoke inhibit feature to protect

registers against unwanted writing

■

Encoder input

■

Hall effect sensors interface

■

Total vector control loop: 21 µs in sensorless mode

The dual ADC architecture allows dual sample and

hold capability with 12-bit resolution, 1 µs conversion

time. The dual ADC is controlled by two independent

sequencers with discontinuous mode, multiple trigger

sources, and channel-by-channel programmable

sampling time.

This dedicated set of peripherals combined with the

high performance of the Cortex-M3 core allows your

software to shorten the total vector control loop to

21 µs (sensorless mode, three-phase PMSM motor).

The CPU load is below 25% at 10 kHz current sampling

frequency, allowing the STM32 to perform other tasks

than motor control in the application.

Supporting tools include the STM32 motor control

starter kit (STM3210B-MCKIT), a complete hardware

platform and ready-to-run demo based on the STM32

motor control firmware library. It allows rapid feature

evaluation and easy implementation of sensor and

sensorless vector-based motor control for three-phase

PMSM and AC induction motors.
