Technology
Rotating e-machines that make bearing forces. No other actuators needed.
Retrofit Capability
Many standard motor/generators can be retrofitted with our bearing-assist technology.
Oil-Free Bearings
Improve material compatibility by adding bearing-assist capabilities without needing oil.
Less Axial Length
No need to give up precious axial shaft length for components in the bearing system.
Cost Effective
Reuse your existing motor and drive without buying a full new system.
System Integration
New capabilities mean better system integration and compactness for your hermetic machinery.
Power Density
Our approach uses more axial length for power conversion to increase system power density.
Core Capabilities
Our unique motor and drive technology enables the capabilities of active magnetic bearings within electric motors and generators. No additional actuators needed.
Motibera's bearing-assist motor acts as both a radial bearing and a motor/generator.
Integrating Motibera Bearing-Assist Technology
Motibera's bearing drive creates and controls electromagnetic forces on the rotor.
A specialized stator winding exposes additional terminals for force creation---the original 3-phase terminals continue to be connected to the standard motor drive to make torque, while Motibera's bearing drive connects to new terminals in the winding.
Our proprietary winding approach uses a single installed winding like standard motors and generators, instead of requiring multiple winding sets. The Motibera bearing drive dynamically allocates the winding current towards force and torque at run-time, enabling the highest power density for a given force output.
Bearing-Assist Applications
Choose between two approaches for your application to make the best use of our bearing-assist technology.

Working with Motibera
Working with Motibera is as easy as these three steps:
-
1. Feasibility Study and Consulting
You provide us information about your existing motor/generator system and we determine the best way to add the bearing-assist capability. Typically, this involves simple modifications to the stator winding, and sometimes only involves re-configuring the connections of individual winding coils in the terminal box.
-
2. Selection and Delivery of Motibera Bearing Drive
Once Motibera has determined the best approach to retrofitting your system with our bearing-assist technology, we will provide a compatible Motibera Bearing Drive unit.
-
3. Commissioning and Bring-Up of Bearing-Assist Capability
The last step involves on-site commissioning time with Motibera's top engineering staff to help you get the bearing-assist force creation working the best possible for your system. We help you all the way to the end!
