HAMBURG, Germany--(BUSINESS WIRE)--TRINAMIC Motion Control, a leading global developer of motor and motion control technologies, today revealed its latest patent-pending technology for stepper motors. Dubbed stealthChop, the new technology significantly reduces the noise of conventional stepper motor operation.
Manufacturer: Trinamic Motion Control GmbH Description: IC MTR DRVR BIPOLAR 8-60V 48TQFP Packaging: Digi-Reel® (Surcharge for the reel of $7) Part Status: Obsolete Motor Type - Stepper: Bipolar Function: Driver - Fully Integrated, Control and Power Stage Output Configuration: Half Bridge (4) Interface: SPI, Step/Direction. TRINAMIC Motion Control GmbH & Co. KG now sells a new high-power gate driver for PMSM servo or BLDC motors. The chip enables powerful, flexible designs with high current profiles that can be tuned to perfectly match the motors in nearly any application.
Motors operating at low speed exhibit a phenomenon known as magnetostriction, which causes an audible low frequency ‘hum.’ This low-frequency noise is well known as the 60Hz hum that emanates from transmission lines and transformers. Trinamic’s stealthChop minimizes magnetostriction by implementing a PWM algorithm that relies predominantly on voltage modulation for motor control at lower speeds. This technology minimizes PWM current fluctuation, which is the primary cause of low-speed hum.
“Stepper motors used in automation must respect the needs of their human overlords. The continuous noise of individual stepper motors in a laboratory environment may be rather distracting, and the din from hundreds of stepper motors in an industrial implementation can be deafening,” explained TRINAMIC R & D Chief Dr. Stephan Kubisch. “Our customers asked Trinamic to perfect a commutation scheme for lower step frequencies that reduces noise. We made it self-tuning, easy to use and added an automated switch to transition to higher frequencies.”
Noise limitations are especially desirable in applications that normally occur in close proximity to human operators, in applications where multiple stepper motors are in use, in video surveillance applications where installations near walls and ceilings amplify noise, and in consumer applications, like home automation and air conditioning, where users expect minimal noise.
TRINAMIC devices that implement this new stealthChop technology have achieved measured noise levels 10 dB below traditional stepper motor drive ICs.

“For many manufacturers, miniaturization is transforming their organization by allowing smaller and decentralized devices, resulting in leaner processes and reduced storage and logistics cost,” explains Trinamic’s CEO Michael Randt. “With the NEMA 8 motor mountable TMCM-1210, Trinamic once more demonstrates its ambition to be at the forefront of technology”
The general trend towards miniaturization is driven by a demand for compact, decentralized devices instead of huge machines. This trend is visible in all kinds of applications such as microbiology instrumentation, lab automation, scientific test equipment and micro precision systems.

Like all other TMCM modules, the TMCM-1210 embeds advanced motor control functions, as well as motion control and PLC features, into a tiny and cost-efficient module. The new driver module (20mm x 20mm) is equipped with an RS485 interface and Trinamic’s proprietary TMCL™ protocol. Together with the free TMCL-IDE, this allows for easy implementation of a standalone program flow. Graphical tools and wizards guide through the parameterization.
Being based on Trinamic’s latest stepper motor driver generation, the TMCM-1210 offers leading edge current control technologies. A high-resolution microstepping with up to 256 equidistant microsteps per full-step generates a total resolution of 51.200 steps per rotation, resulting in vibration free positioning. With Trinamic’s patented stealthChop™ current control for silent positioning at low speed and spreadCycle™ for highest performance at high speed, the module provides superior performance wherever small stepper motors are used.

The integrated sixPoint™ ramp generator allows for precise and rapid positioning. Even in environments where parameters and target positions must be changed during motion. The module has a reference switch input that can be programmed as left or right limit switch. In addition, it comes with stallGuard2™ for sensorless homing and an integrated rotary hall encoder.
