TRINAMIC Motion Control announces
the TMC4671 – the world’s first fully integrated servo controller IC providing
field-oriented control for BLDC/PMSM and 2-phase stepper motors, as well as DC motors
and voice coils.
Hamburg, June 18, 2018 - The trend towards
automating everything around us has increased the demand for energy efficient
control even of the smallest motors, so the focus on reducing energy
consumption has shifted from large motors also to the smaller, embedded
applications, where the use of large inverters is no option.
The
TMC4671 addresses this market by embedding all necessary control loops in
rugged, reliable state-machines. By offloading real-time critical tasks from
the processor and software and implementing all control functions in hardware,
the TMC4671 offers a crucial benefit: it takes care of all control functions
itself. Integrated ADCs, position sensor interfaces, and position interpolators
enable a fully functional servo controller for a wide range of servo
applications such as robotics, pick and place machines, factory automation,
e-mobility, lab automation, and blowers.
“Application
layer or bus protocol firmware needs to be updated over the typical lifetime of
a product,” explains TRINAMICs founder and CEO Michael Randt. “Having all real-time
tasks embodied in dedicated, proven and reliable hardware, minimizes the effort
for the initial firmware development and these updates and thus reduces the
total cost of ownership.”
The
TMC4671 is designed to rapidly decrease time to market for highly performant
servo controllers while maximizing drive efficiency as well as dynamics. With
all time critical calculations in hardware, just a few lines of code are
necessary to develop a dynamic servo controller.
It
offers high switching frequency and controller update rates of up to 100kHz and
has filtering and interpolation features like the digital Hall signal
interpolation for smoother operation. The IC can work with various encoders such
as simple digital or analog Hall sensors over A/B/Z incremental and
high-resolution sin/cos analog encoders. Sensors can be flexibly mapped as an
input for position and velocity control loops. With its delta sigma current
sensing ADCs, the TMC4671 is perfectly suited for isolated delta sigma
frontends.
The
TMC4671 is available immediately in QFN76 package through distribution for USD
7.20 at 1000 units. Besides the IC, Trinamic will also offer the TMC4671-BOB
and TMC4671-EVAL for Trinamic’s modular Landungsbrücke Evaluation System.
Together with Trinamic’s powerful tools including TMCL-IDE, this speeds up
development and design-in processes considerably.
