Neodymium NdFeB Disc Magnets
Ideal where compact size with maximum strength is required
Industry: Power Generation
We were approached by a company to supply a magnetic rotor assembly for a generator application. The high speed rotor would be used for multi-phase voltage generation. The power electronics would be simple to keep costs down. The customer wanted same magnitude voltage output in each phase.
We provide the ability to produce rotor assemblies in-house. Such rotors can be sleeved (Inconel, glass fibre, etc) to keep the magnets mechanically on the rotor. The rotors can also be mechanically balanced to meet customer anti-vibration requirements (to minimise bearing wear for example). We also offer a little-known service called magnetic balancing.
Magnetic balancing is where we Helmholtz coil test the magnets to determine each magnet’s magnetic performance. We can then place the magnets on the rotor in such a way that each phase of coil winding will “see” the same levels of magnetic performance. The magnet placement is such that we have magnetically tuned / magnetically balanced the performance in each phase of coil winding. The end result is that the generated voltages in each phase are more evenly balanced with nearer to equal voltage magnitudes allowing for cheaper and simpler power electronics to be used.
Such magnetic and mechanical balancing on rotors by Eclipse Magnetics can be used in generators, motors and even on other electrical machines, actuators and drives.
"We were delighted with the service provided by Eclipse Magnetics; from the initial site survey through to delivery."
"I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!"
"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."
"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."
"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."
“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”
"Here at Qualflow, we base our business on a philosophy of make the product simple to use, reliable and cost-effective. Eclipse Magnetics’ neodymium magnets offer the strongest magnetic performance, and are nickel plated, making them a cost effective.."
"The Ultralift Plus magnetic lifter from Eclipse Magnetics is the perfect solution for the pick-up and transportation of the ultrasonic calibration blocks in our facility"
"The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean..."
