Abstract :
A software package based on the finite-element technique has been used to compute three-dimensional magnetic fields and static forces in brushless DC linear motors. As the field flux-source, two different types of permanent magnets, one of them of the high-energy neodymium-iron-boron type, have been used in computer models. Motors with the same specifications as the computer models were built and experimental results obtained from them agreed well with the computed results
