Trinamic Motion Control GmbH & Co. KG, now part of Maxim Integrated Products, Inc., has claimed the smallest and lowest-power single-axis servo controller/driver module with integrated motion control. The TMCM-1321 servo controller/driver module targets two-phase bipolar stepper motors in robotics and automation equipment.

This stepper motor module optimizes speed and synchronization of axes for faster throughput while also reducing power loss by 75 percent thanks to Trinamic’s closed-loop technology, according to the company. In addition, it features an on-board magnetic encoder and digital inputs for an optical encoder, which is said to simplify the servo control for advanced feedback and diagnostics.
In addition to the power savings and smaller solution size of 784 mm2, the TMCM-1321 module features linear ramping, Trinamic SixPoint ramping, as well as advanced S-shaped ramping to speed effective transfer time. In combination with an RS-485 interface and Trinamic’s integrated development environment, the TMCM-1321 module simplifies design and reduces stepper motor size by more than three times, said the company.

The stepper motor driver drives up to 0.7 A RMS motor phase current at 24 V nominal and provides high micro step resolution, up to 256 micro steps per full step. It also features the automatic current scaling algorithm CoolStep for energy savings and cooler operation.
Available now, the TMCM-1321 module is priced at $119.40 each through Trinamic authorized distributors.
Trinamic also offers the TMCM-1278 smart stepper motor driver module and PD60/86-1278 PANdrive motor driver solutions for high-power stepper motors that enable developers to scale systems without changing their system design.
