[On-Line] Crane Physics and Drive sizing (CR-BASICS)


  • This course teaches participants to understand the cranes mechanical system and its demand for physical quantities like power, torque, speed, acceleration etc. It provides general understanding of AC motor theory as well as AC converter power electronics. It enables the participants to size the complete electrical drive systems for crane.

  • This course has a Course price of EUR 1.650, but is free for Partners of Cranes Erlangen.
Type Face-to-face training
Duration 5 days
