Powerful stepper motor servo modules for driving three axes

 | 

Both the TMCM-3314 and TMCM-3315 are the most powerful stepper servo module for controlling multiple axes with 6.7A.

Hamburg, 23 July 2018 - TRINAMIC Motion Control GmbH & Co. KG announces their impressive modules for 2-phase bipolar stepper motors with separate encoder and HOME / STOP inputs for each axis. Ensuring the stepper motors are driven accordingly, the robust stepper motor servo modules carry the potent TMC5160 and the dedicated closed-loop motion controller TMC4361.

“Next to time constraints, developers are increasingly limited by budget. As servo drives with gearboxes are not only expensive but also inefficient to use, more and more companies turn towards other solutions. Providing higher torque than servo motors of comparable size at low speeds, stepper motors are cheap alternatives for servo motors with gearboxes. And with the TMCM-3314 and TMCM-3315, you get the efficiency of a servo at the cost of a stepper motor with all the power you need,” clarifies Michael Randt, Founder and CEO of TRINAMIC Motion Control.

The powerful boards drive three 2-phase bipolar stepper motors up to 6.7A while retaining energy efficiency. Ideal for handling liquids and sensitive goods, the stepper motor servo modules for stepper motors with A/B/N quadrature encoders have S-shaped ramping for precise and fast positioning. Other special Trinamic features, such as the easy to implement CoolStep and StealthChop, allow for silent, sensorless load-dependent current control.

Depending on the application requirements, both the TMCM-3314 and the TMCM-3315 are up for the task with the only difference being the supported interface. CAN, RS485 and USB interfaces are supported by the TMCM-3314, while the TMCM-3315 uses EtherCAT™ and USB for communication.

The TMCM-3314 and TMCM-3315 are available from the beginning of August through distribution at a single unit. The board has dimensions of 280mm x 100mm.
