Publication number: 20220385162Abstract: 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).Type: ApplicationFiled: November 5, 2020Publication date: December 1, 2022Inventors: Yingjie LI, Arbi GHARAKHANI SIRAKI, Rachel OZER, Shahriyar BEIZAEE, Erik JOHNSON
