Internship description

The internship project aims to evaluate different driver solutions for stepper motors used in our products.

Main activities:

  • Assess the existing motor driver solution
  • Set up the various motor drivers to be tested
  • Take measurements and evaluate performance
  • Compare and summarise the results obtained 

Profile required

Key point: 

  • Object-oriented programming (Python) 
  • Basic knowledge of motion control (motor control) 
  • Basic knowledge of electronics 
  • Knowledge of industrial communication protocols (EtherCAT, Modbus RTU/TCP, CAN)
