Publication number: 20140312717Abstract: 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.Type: ApplicationFiled: July 3, 2014Publication date: October 23, 2014Inventors: Georgo Zorz Angelis, David Biloen

Publication number: 20090209842Abstract: The invention relates to a magnetic resonance imaging system which comprises means for generating a static magnetic field and a gradient coils system for generating a time varying magnetic gradient field by use of a first electrical current and a second electrical current. The gradient coils system is located in the magnetic field and the gradient coils system has a plurality of vibrational modes. Lorentz forces are generated due to the interaction of the first and/or second electrical currents with the superposition of the static magnetic field and the magnetic gradient field. The gradient coils system and/or the first electrical current are adapted so that the integral of the in-products of said Lorentz forces and a vibrational mode of said plurality of vibrational modes is at a value close to zero, wherein said in-products are determined for all points of the gradient coils system, and wherein the integral is determined by summing the in-products determined for all the points.Type: ApplicationFiled: July 3, 2007Publication date: August 20, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.
