Abstract:
An ironless magnetic motor includes a magnetic track and a forcer. The forcer is oriented in a magnetic field across a linear air gap of the magnetic track to generate a drive force parallel to the X drive axis and orthogonal to the Z levitation axis in response to a commutation drive current and to generate a force orthogonal to the X drive axis in response to a commutation coil current being superimposed on and phase shifted from the commutation drive current. To this end, a set of levitating turns of the coil parallel to the X drive axis and orthogonal to the Z levitation axis may be internal or external to magnetic field, and the forcer may be centered or offset from a center X-Z longitudinal axis (CP) of the linear air gap.
