Whether it is a simple rotor asssembly for low cost low speed use or a high specification magnetically balanced rotor with mechanical balancing, we can produce and supply high quality magnetic assemblies for your application.
Magnetic Balancing - some applications require the back-emf (generated voltage) in each phase to be of equal magnitude (to keep the power electronics simpler and lower cost). To allow this, it is possible for the magnetic output of each magnet to be measured and then the magnets can be assembled onto the rotor so that the total magnetic field each phase will see is as equal as possible. This is called magnetic balancing (or magnetic tuning).
High Speed Rotors - in some applications the magnets need additional sleeving to assist in holding the magnets in place. We work with customers, often using their designs, to ensure the magnets stay on the rotor at all times.
Mechanical Balancing - high speed rotors often require mechanical balancing to limit bearing damage, internal stresses and strains, noise, etc. We can balance the rotors to meet customer requirements.
Assembling - we can either assemble fully magnetised magnets onto the rotor. Or we can look to assembly unmagnetised magnets onto the rotor and magnetise afterwards in situ (if the design allows post-assembly magnetising to be feasible).
Machining - sometimes, especially for adding sleeves to rotors or when the air gap from rotor to stator is very small, the assembly outer radius needs to be precision ground. We can do this (but be aware that this may possibly affect the magnetic balancing - if you require more information on this effect please contact us).
Magnetic rotor assemblies include:- motors, generators, high speed actuators, wind turbines, magnetic pump couplings, printer rotors, direct drives, etc.
