IRONLESS MAGNETIC LINEAR MOTORS HAVING LEVITATING AND TRANSVERSAL FORCE CAPACITIES

A ironless magnetic motor (21-23) employs a magnetic track (30) and a forcer (40). The forcer (40) is orientated in relations to a magnetic field ( ) across a linear air gap of the magnetic track (30) to generate a drive force (FX) parallel to the X drive axis and orthogonal to the Z levitation axis...

Zusammenfassung:A ironless magnetic motor (21-23) employs a magnetic track (30) and a forcer (40). The forcer (40) is orientated in relations to a magnetic field ( ) across a linear air gap of the magnetic track (30) to generate a drive force (FX) parallel to the X drive axis and orthogonal to the Z levitation axis in response to a commutation drive current (IX) and to generate a force (FZ, FY) orthogonal to the X drive axis in response to a commutation coil current (IZ, IY) being superimposed on and phase shifted from the commutation drive current (IX). To this end, a set of levitating turns of the coil (41) parallel to the X drive axis and orthogonal to the Z levitation axis may be internal or external to magnetic field ( ), and the forcer (40) may be centered or offset from a center X-Z longitudinal axis (CP) of the linear air gap.
