Abstract: Electrical windings for a low-pressure environment are provided. The electrical windings include a body having an aperture and electrical conductors wound about the aperture in the body; a conductive layer at the body, the conductive layer arranged to electrically shield the electrical conductors; electrical connectors at one or more external sides of the body, the electrical connectors electrically connected to the electrical conductors; an insulating housing containing electrical connections between the electrical connectors and the electrical conductors; a conducting faceplate at the insulating housing, grounding portions of the electrical connectors attached to the conducting faceplate; and a conductive coating on the insulating housing, the conductive coating electrically connected to the conducting faceplate and the conductive layer.

Abstract: A system (100), electromagnetic actuator (102) and track (101) for braking are provided. The actuator (102) includes pole portions (109) extending from back-iron portions. Respective longitudinal axes (104) of the pole portions (109) are arranged about parallel to one another and about perpendicular to a common movement axis (104). A pole pitch of the pole portions (109) is selected to induce eddy currents in a segmented track (101), such that the eddy currents are present in a skin depth at more than one surface of segments (105) of the segmented track (101) when the pole portions (109) are moving at given speeds. Eddy current generated losses occupy about an entirety of a volume of a segment (105) of the track (101) below a given intermediate speed, and the eddy current generated losses occupy at least one third of the volume of the segment (105) at a given maximum speed greater than the given intermediate speed. Individually controllable electrical windings are around respective pole portions (109).
