The basic principle of all Zytec Contact-free Magnetic Couplings

The principle of all Zytec Couplings is the same as used in electric motors. The magnetic coupling works by rotating copper discs (Inductor) at the motor side and a Magnet Rotor at the load side to transfer torque. The permanent magnets mounted in the Magnet Rotor change the magnetic fields in the Inductor and creates loops of electrical current (called Eddy Currents) which results in a drag force. As soon as the Inductor, driven by the motor rotates,  the Magnet Rotor rotates under the influence of the magnetic field without any physical contact between the Inductor and the Magnet Rotor. By increasing or decreasing the air gap between the Inductor and the Magnet Rotor the speed of the load can be controlled. This contact-free controllable connection offers many advantages. You will find on the page General Benefits (link on the right side) the benefits which apply to all the Zytec couplings and below the specific applications areas and benefits per coupling type.


You are here

A fixed speed coupling

As an alternative solution to the current fixed coupling (claw, rubber, tooth, pin, fluid coupling), the reliability of the entire system is increased and alignment is not critical or relevant anymore.

Adjustable Speed Coupling

Sets the installation in the optimum operating point which is often inevitable by mandatory safety factors during the design process or later implemented process optimizations.

Variable Speed Coupling

As an alternative to a controlled choke valve or a Variable Frequency Drive (VFD) or a variable fluid coupling to control the process.
