Tecnotion produces linear motors for the high tech automation and semiconductor markets. Orthocyclically wound coils give the best performance because the largest number of windings can be packed into a given volume, as opposed to "wild winding", where the windings fall where they may. Additionally, the anisotropic heat conduction perpendicular to the wire direction is optimized because each winding is positioned exactly next to all six of its neighbors, maximizing the contact surface. A thorough understanding of the thermal performance is necessary to understand and predict the motor performance.
