Elephanta Controller
The Most Powerful in the Industry
The Elephanta® digital controller is the most powerful magnetic bearing controller in the industry and the basis for the largest, most critical turbomachinery applications, including subsea.
Recommended for machinery in the power range of 15 MW to 80 MW, the Elephanta controller offers 4-, 5-, 6- or 7-axis control configuration. The controller provides high processing performance, automated commissioning and tuning, built-in condition monitoring and remote adjustment capabilities.
The integrity of the functional testing, verification and development of new features for the controller, performed on the world’s largest super-critical test rig, is far superior to simulation testing methods used by others.
