Esmacat Motor Driver 250

High Speed Control for Robotic Applications


The Esmacat Motor Driver 250 is a powerful brushed and brushless motor driver for high speed control that robotic applications demand, especially when safety around humans is a priority. It is capable of up to 250W continuous (750W peak) and integrating quadrature encoders and hall sensor inputs along with 7 Digital IO pins and 2 analog inputs for integration of any other sensors that are used in the motor system. The EtherCAT protocol and Power-over-EtherCAT (POE) technology allows high speed communication and flexible connectivity by supporting daisy-chain wiring. and it is capable of continuous motor power of up to 250W. The Motor Driver 250 is a part of the Esmacat suite and is the ideal motor control solution for both novice and expert robotics engineers due to its easy programmable master software and hardware setup.

*Note: The Esmacat Motor Driver 250 uses a PoE input voltage rating of 24VDC. Please see datasheet for more details.*

Incorporating the Esmacat Motor Driver 250 Into Your Project

The Esmacat Motor Driver 250 is fitted with an ESCON module for motor control. The module can be easily setup/tuned with Maxon's ESCON studio.


Once the motor parameters are set on ESCON studio, the motor driver is correctly powered via a 24 V PoE Injector (separate from the motor power supply), and the EtherCAT software is coded to your needs, you are ready to incorporate the motor driver into your project!


We have plenty of supporting material on our tutorials page, including this YouTube video and many more, on how to get started with the motor driver. All our material uses the Esmacat Master software for simple setup but the motor driver is compatible with all EtherCAT masters via a few extra steps. 


Master Software

Esmacat provides EtherCAT master software to control the motor driver (position control and velocity control included) through a daisy-chain topology filled with Ethernet cables from an EtherCAT master. Our free open-source master software compatible on both Windows and Linux can be found on our Software page. Our motor driver is also compatible with 3rd party EtherCAT master devices.

Maxon's ESCON Studio

ESCON studio is used to set the motor parameters and tune the motor driver according to your needs. More information on how to use ESCON studio with the Esmacat motor driver 250 can be found on our Guidance of ESCON Studio Setup document.
