Magnetic couplingsSintex develops and manufactures couplings based on the traditional method using magnets attached with adhesive, as well as our patented powder-based solution where we encapsulate powder.
Our specialists calculate and optimise solutions using finite element programs, 3D simulations, force calculations, motor calculations, etc.
Magnetic couplings cover a range of different types – including disk couplings, separator cans and other magnetic configurations. The magnetic function of the couplings can be either linear or rotating.
Magnetic couplings consists simply of two units. A drive unit and a slave unit. The two units are not in contact. The coupling functions via the contact-less transfer of power. This means that magnetic solutions do not wear, in contrast to traditional solutions. Magnetic couplings are therefore maintenance-free.
For couplings with two rotating units, it is possible to place a separator can between two rotating units, such that two different media can be separated out. For some types of couplings, it is also possible to hermetically encapsulate the coupling in a stainless steel casing. The 100% sealed systems make it possible to avoid corrosion, and the coupling can rotate directly in various liquids and aggressive environments.
Compared to mechanical couplings, magnetic couplings offer these advantages:
- Power is transferred without contact – no risk of breakdown
- Long maintenance-free lifetime
- No need for lubricant – no friction
- High power transfer
- Reduced load on the system
- Absorption of large eccentricity differences between shafts (greater flexibility in radial and axial placement)
- High-temperature solutions
