Maxim Integrated Releases Trinamic Servo Controller/Driver Module

TRINAMIC Motion Control GmbH & Co. KG, now part of Maxim Integrated Products, Inc (NASDAQ: MXIM), today announced the industry’s smallest, lowest power, single-axis servo controller/drive module with integrated motion control. The new TMCM-1321 servo controller/driver module is used to support the operation of two-phase bipolar stepper motors in robotics and automation equipment, optimizing speed control and synchronization of each axis, and reducing power consumption by 75% while increasing production. Modules feature onboard magnetic encoders and digital inputs for optical encoders to simplify servo control, enabling advanced feedback and diagnostics; 3X smaller size compared to similar stepper motor solutions.

The TMCM-1321 module uses linear ramp function control, known as Trinamic SixPoint™ ramp function, and advanced S-shaped ramp function control to speed up effective transfer time. Trinamic’s closed-loop control technology uses direct feedback to automatically reduce power consumption by 75%. With the RS-485 interface and Trinamic’s integrated development environment, the TMCM-1321 module can simplify the design and reduce the size of the stepper motor by more than 3 times.

main advantage

Reduced power consumption: Compared to similar stepper motor solutions, Trinamic closed-loop control technology offers the best energy savings in the industry.

Increase productivity: Improve effective transit time by implementing a ramp function profile that matches application requirements.

Small size solution: The TMCM-1321 module cooperates with the magnetic encoder and digital ABN input to provide the smallest size single axis servo controller/driver solution, occupying an area of ​​only 784 mm2.


“When choosing an energy-efficient drive, engineers tend to gravitate towards servo drives. However, stepper motors have much higher torque at low speeds than servo motors of comparable size,” said Jonas Proeger, business director at Trinamic. The motor, combined with closed-loop control technology, can get rid of expensive and inefficient gearboxes without sacrificing positioning accuracy to get the efficiency of a servo motor at the cost of a stepper motor.”

Availability and Price

The TMCM-1321 module is available now for $119.40 through authorized Trinamic dealers.
