Portfolio of active magnetic bearing components
MECOS offers a comprehensive portfolio of active magnetic bearing components for a wide range of applications. With our extensive expertise and experience, we develop customer-specific solutions tailored to individual requirements.
Pre-assembled AMB cartridge
The AMB cartridge is a customer-specific assembly. Depending on the application requirements, it may include the radial bearing stator, touchdown bearings and sensor units. An axial bearing can also be integrated. The cartridge design enables fast and efficient assembly at the customer’s site.
Radial bearing stator
The radial bearing stator consists of multiple electromagnet pairs (coils) positioned around the rotor. Lamination stacks are typically shrink-fitted onto the rotor to minimize eddy current losses at high rotational speeds. Radial bearings can be designed as either hetero- or homopolar systems.
Axial bearing and thrust disc
The axial bearing consists of two ring-shaped electromagnets positioned on either side of a thrust disc. The thrust disc is a solid ferromagnetic component integrated into the rotor. The axial bearing controls the rotor position in the axial direction. The specific bearing design depends on the available installation space and operating speed requirements. Various design concepts are available for the arrangement of axial bearings and thrust discs.
Sensor units
MECOS sensor units are the result of many years of experience in eddy-current and inductive sensor technology. They are available in a variety of sizes and are specifically designed to meet the demanding requirements of active magnetic bearing systems, including a wide operating temperature range, high precision, immunity to external magnetic fields, robustness and cost efficiency.
Touchdown bearings
Touchdown bearings support the rotor during standstill and protect the system in the unlikely event of a control system failure during operation. They help prevent severe damage by safely accommodating overload conditions and rare fault scenarios.
Rotor components
MECOS designs key rotor components, including lamination stacks, sensor targets, thrust discs and touchdown landing sleeves. These components are typically shrink-fitted onto the rotor. Depending on the application, the rotor and thrust disc can also be machined or manufactured as a single integrated component.
