Stellaris® DK-LM4F-DRV8312
ARM® Cortex™-M4F Motor controlCARD Kit for
3-Phase Brushless DC (BLDC) Motors
Texas Instruments introduces the first floating-point ARM Cortex-M4F sensorless field-oriented
control (FOC) motor-control kit that also lets developers instantly spin their BLDC and PMSM motors.
•ꢀ Tractionꢀandꢀtransport
•ꢀ Tools
The Texas Instruments Medium Voltage Digital
Motor Control Kit for Stellaris® Microcontrollers
(DK‑LM4F‑DRV8312) is a development
platform for spinning three‑phase brushless DC
(BLDC) and permanent magnet synchronous
motors (PMSMs).
Features
The DK‑LM4F‑DRV8312 motor control kit
contains a high‑performance Stellaris LM4F
microcontroller‑based controlCARD module
compatible with other TI motor‑control
platforms.

Kit contents
The DK‑LM4F‑DRV8312 kit is a bundle of the
following components:
The low‑cost Stellaris LM4F211
microcontroller on the MDL‑LM4F211CNCD
controlCARD module comes pre‑programmed
with the necessary firmware in Flash

Brushless DC Motor Driver
TI’s Stellaris Motor controlCARD kit
provides an easy-to-use, low-cost, all-
inclusive solution for three-phase motor-
control application developers.
InstaSPIN‑BLDC and Sensorless (Sliding
Mode Observer, or SMO) FOC
memory to run TI’s InstaSPIN™‑BLDC motor
control solution out‑of‑the‑box. The system
automatically spins a user’s three‑phase
brushless DC motor (assuming operation with
the included 24‑V, 2.5‑A supply). The kit also
includes a project to spin the included PMSM
using a sensorless sliding mode observer FOC
technique.
The operation of both solutions can be
controlled and viewed across a USB interface
using an included GUI. Follow the steps in
the DK‑LM4F‑DRV8312 kit’s README First
document to quickly get up and running.

In addition to instantly spinning your motor,
the kit also demonstrates the InstaSPIN‑BLDC
motor control solution’s operational advantages
with simplified tuning, immediate acceleration
adaptation, reliable low‑speed operation, and
more.
