TRINAMIC Offers New Dual-Axis Stepper Motor Controller-Driver System-on-Chip
HAMBURG, Germany --(Business Wire)--
TRINAMIC Motion Control, a leading global developer of motor and motion
control technologies, today announced its flagship stepper motor
controller-driver SoC. The new TMC5062 is a monolithic dual-axis motor
controller and driver that incorporates eight of Trinamic's patented or
patent-pending motion control technologies. This new SoC is the world's
first device to integrate dcStep™, Trinamic's proprietary technology for
automatically adapting motor velocity for sudden increases in load.
With its integrated motion control hardware, the TMC5062 can relieve any
MCU with a SPI or single wire UART interface from all real-time motor
calculations, including positioning and velocity ramp calculation.
Trinamic's patented sixPoint™ ramp generator supports stepper motor
calculation of high-resolution current values with up to 256 micro-steps
per full-step. And its integrated power stage technology--for up to 1.5A
peak current per motor--incorporates Trinamic's proven spreadCycle™
chopper unit for smooth commutation.
Trinamic's latest innovation, dcStep, addresses the need for stepper
motors to maintain positional (or step) self-awareness without costly
feedback circuitry. Without feedback circuits, significant operating
margins must be implemented so that motor torque and velocity limits are
not exceeded. Trinamic's new dcStep technology allows for momentary
increases in torque to compensate for sudden increases in load
resistance without losing step count, significantly reducing the safety
margin that would otherwise be required by a stepper motor control
"Trinamic is focused on continual improvements in stepper motor system
design," explained Trinamic Founder and CEO Michael Randt. "Our new
dcStep techology lowers system cost and energy consumption by shrinking
excess safety margin, which reduces the motor size required for a
specific application. This, in turn, leads to cooler operating temps,
more compact board design, and the elimination of fans and heat sinks. A
single technology like dcStep accelerates miniaturization, efficiency
and ease-of use."
Connected to a host microcontroller through an SPI or single wire
interface, the TMC5062 executes all real-time position and velocity
stepper motor calculations, and also directly drives coil currents for
dual integrated stepper motor drives. This highly integrated dual-axis
motion controller is ideal for pan and tilt control used in a wide
variety of high volume applications: in millions of IP video cameras
being deployed globally for security, border control and other remote
viewing applications; in solar power heliostat mirror arrays, where tens
of thousands to millions of mirrors reflect sunlight throughout the day
to power a steam turbine for electricity generation; in medical and lab
applications, like in-vitro analysis, that require X/Y motion control;
and in 3D printers.
With a 1.5A peak current, the TMC5062 is ideal for use with stepper
motors up to NEMA size 17, covering most of the typical hybrid stepper
applications. The TMC5062 is software compatible with Trinamic's popular
dual-axis TMC5031 motion control and driver IC, upgrading it's
functionality with dcStep and an integrated ABN quadrature encoder
interface. The new device implements a subset of relevant instructions
for dual-axis operation and for six-point acceleration profiles.
Production Volumes of TMC5062-LA are available from August 2014.
The device is offered in a QFN48 (7mm x 7mm) package, priced at below
USD 5 in 1,000 unit volumes.
To support rapid product development and prototyping, Trinamic offers a
complete TMC5062 design kit with evaluation board and intuitive PC-based
development software. The TMC5062 also comes with free reference source
code, schematics and board layouts.
