The Kinetis motor suite is the newest addition
to Freescale’s MCU enablement bundle which
includes a broad range of IDEs, auto code gen-
erators, the Freescale MQX RTOS and appli-
cation-specific software libraries. Designed
for developers of all experience levels, Kine-
tis motor suite makes motor control develop-
ment simpler, faster and more efficient.
A developer can identify (through simple
parameter pre-loading), tune (using just one
knob) and control (across variable speeds and
loads) any type of 3-phase synchronous or
asynchronous motor regardless of power level.
The centrepiece is LineStream Technologies
disturbance compensating algorithm, which
helps to ensures high performance even in
highly dynamic operating conditions and
dramatically simplifies control loop tuning
by replacing outmoded, trial and error based
PID methods. Managed through a simple
graphical user interface (GUI), this patented
technology eliminates what is a barrier to
entry for many – the need for in-depth motor
control algorithm knowledge.
This enables more precise motor tuning,
sharper system response and reduced sys-
tem degradation over time. Kinetis motor
suite three software components observe,
tune, and manage motor control system
operation: 1) Kinetis motor observer –
advanced algorithms pre-programmed into
the MCU that automate tuning of control
loops and estimation blocks; 2) Kinetis
motor tuner – an intuitive GUI for config-
uring motor observer algorithms based on
self-identified motor parameters; 3) Kine-
tis motor manager – a real-time, non-in-
trusive display of system variables with
extensive data tracing capabilities that opti-
mizes motor system performance.
Two versions of the Kinetis motor suite
will be offered based on application type
and user knowledge. In the turnkey version
developers will select their desired appli-
cation – initially fans, compressors and
pumps (further options will follow) – fine
tune as needed, then deploy without ever
having to write code. Alternatively, motor
specific solutions for sensored and sensor-
less BLDC, PMSM and ACIM will allow the
developer to transition between the KMS
GUI and their IDE to write and debug their
application code. MCUs pre-programmed
with the Kinetis motor suite software are
expected to be available to order in the first
quarter of 2015.
Freescale also provides additional GUI-based
configuration/debug tools and software
libraries. FreeMASTER is a simple and high-
ly-customizable, GUI-based, real-time debug
monitor which supports the Motor Control
Application Tuner (MCAT) plug-in leverag-
ing Freescale reference design code. Devel-
opers using Matlab/Simulink model-based
design are also supported by the Motor
Control Toolbox. Complimentary software
libraries for motor control, math, filter and
other general functions, as well as a core self-
test library for IEC 60730 certification are
also provided. The TWR-KV10Z32, TWR-
KV31F120M and TWR-KV46F150M Frees-
cale Tower System MCU modules along with
the TWR-MC-LV3PH motor driver module
provide the hardware for MCU evaluation
and development. These include precompiled
examples for BLDC trapezoidal and PMSM
FOC algorithms that can be evaluated within
CodeWarrior and Kinetis Design Studio
IDEs, as well third party IDEs including the
IAR Embedded Workbench and ARM Keil
Microcontroller Development Kit.
