On-board Motor Control Connectors

The SDK-ST10F269 board provides an embedded solution (3 modular connectors) for power

requirements up to 3000W, so they are well suited for driving motors (e.g. BLDC, Brushless

Direct Current) via an appropriate external motor board. The various power boards that can be

connected to the SDK-ST10F269 (see

Figure 6) are optimized to support a wide variety of

advanced motor control applications (i.e., the ability to address up to 4 PWM channels). The

power boards also provide these signals:

●

motor turn-on and excitation;

●

brake activation;

●

Forward/Reverse direction; and

●

Hall Effect sensor feedback, which could be combined with encoder signals coming for the

control system in order to perform closed control loops with Pulse Width Modulation

(PWM) and a tachometer dynamo.

ST offers several motor control boards with single chip motor driver solutions (see

: Appendix

C: Motor Board Example Schematics on page 28), for example:

●

L6205 Dual Full Bridge (DC, up to 300W), and

●

L6235 DMOS 3-Phase BLDC (up to 150W)

Note: Refer to the L6205 and L6235 information listed in the

Introduction on page 1 for device

details.

Note: Care must be taken with respect to the L6205-based motor control board and third

connector on the SDK-ST10F269, which offers two PWM signals appropriate for this

development board.
