This paper presents novel analytical expressions which describe the 3D magnetic field of arbitrarily magnetized triangular-shaped charged surfaces. These versatile expressions are suitable to model triangularshaped permanent magnets and can be expanded to any polyhedral shape. Many applications are very suitable to incorporate this modeling technique. Examples are given for the subclass of slotless synchronous linear actuators with a skewed permanent magnet structure and planar magnetic bearings. It is shown that these analytical equations are very suitable to obtain a variety of performance data for the 3D magnetic analysis of slotless linear machines, as well as planar machines and bearings.
