In an ever changing world, limits of current designs are constantly pushed further, requiring genuinely new ideas and technologies to meet new targets.
Active Magnetic Bearings can make a difference in both new designs and redesigns of existing ones.
The prospect of oil-free operation, active vibration control, on-line balancing and fitness for high rotational speed to reduce size of the equipment surely will raise heads among designers of turbomachinery, while increased reliability and remote monitoring will thrill plant managers.
In list of applications we present machines where our Active Magnetic Bearings were decisive in tackling a specific design challenge. We hope that will inspire you, and we will be more than happy to assist you for your application.
The bearing force in a magnetic bearing system is generated by an electromagnet, which serves to hold the rotor in a levitated position. The rotor is monitored constantly by a set of sensors that transmit signals to a digital controller at a rate of up to 10'000 cycles per second. The controller measures any possible deviation of the rotor from its nominal position and supplies the electric current required to maintain rotor stability by means of a power amplifier.
