Trinamic launches multi-axis stepper motor servo module

The TMCM-3351 extends the successful TMCM-351, which has been on the market for more than a decade, by a closed-loop stepper motor servo controller.

Hamburg, 11.06.2018 - TRINAMIC Motion Control GmbH & Co. KG extends its portfolio of TMCM embedded motor control modules. Following the success of the TMCM-351 triple axis board, the TMCM-3351 is designed to be as easy to use as its sibling, but with additional closed-loop stepper motor servo functionality.

The new board drives three 2-phase bipolar stepper motors up to 2.8A. Utilizing Trinamic’s highest performance stepper motor driver IC for external MOSFETs TMC5160 and the dedicated closed-loop motion controller TMC4361, the TMCM-3351 is a cost- and energy-efficient stepper motor servo controller for stepper motors with A/B/N quadrature encoders. Ideal for liquid handling and handling sensitive goods, the S-ramp controller allows for precise and fast positioning.

“If you are looking for an energy efficient drive you are typically looking at servo drives. But, as stepper motors have a considerably higher torque than servo motors of comparable size at low speeds, they often are the solution to get rid of a costly and likewise inefficient gearbox,” explains Trinamic’s CEO Michael Randt. “With our new stepper motor servo drives, you get the best of both worlds. The efficiency of a servo at the cost of a stepper motor.”

Like all other modules by Trinamic, the TMCM-3351 embeds advanced motor and motion control functions, as well as PLC features. Host communication is possible via the RS485, RS232, CAN or USB serial interface using TMCL or the optional CANopen protocol. Together with the free and easy to use TMCL-IDE, the module allows for easy implementation of a standalone program flow and remote-controlled operation. An integrated SixPoint or advanced S-Ramp generator per axis allows for precise and rapid positioning – even in environments where parameters and target positions must be changed during motion.

Designed for bipolar stepper motors with A/B/N encoders, the TMCM-3351 is available from end of July through distribution channels. The board has dimensions of 160mm x 100mm.

Features and benefits:

  • 3-axes controller/driver for 2-phase bipolar stepper motors
  • Supply voltage +11…28V
  • Up to 2.8A RMS motor current
  • S-shaped ramps
  • Closed-loop stepper operation
