Abstract

A commutation current generator (30, 60) for controlling independent orthogonal forces of a magnetic motor (40, 70) including a magnetic track (41, 71) and a forcer (42, 72). The commutation current generator (30, 60) receives a demanded drive force signal (DFX) representative of a demanded drive force required to move the forcer (42, 72) to a desired X drive axis position relative to the magnetic track, a demanded orthogonal force signal (DFZ, DFY) representative of a demanded orthogonal force required to move the forcer (42, 72) to a desired orthogonal axis position relative to the magnetic track, and a sensed drive position signal x(t) representative of a sensed X drive axis position of the forcer (42, 72) relative to the magnetic track. In response thereto, the commutation current generator (30, 60) applies a superimposition of commutation orthogonal currents (IZ1-Iz3, IY1-IY3) on commutation drive currents (IXI-IX3) to the forcer (42, 72) for controlling the independent orthogonal forces.
