Abstract: The present invention relates to a coil module for an electric machine, comprising at least one coil disc comprising a coil carrier made of an electrically insulating material and a plurality of individual windings made of an electrically conductive material and being circumferentially arranged on the coil disc around a center of the coil disc. Each of the windings comprises two active regions extending radially from the center and two passive regions extending tangentially at its radially outer and inner edges, wherein, in a top view of the coil disc, the active regions of different windings do not overlap each other, but each passive region of one of the windings partially overlaps the corresponding passive regions of the two directly adjacent windings. In the active regions, the respective winding in cross-section has a greater thickness in the axial direction than in the passive regions.

Abstract: A suspension includes inner magnets coupled to an inner cylindrical member and outer magnets coupled to an outer cylindrical member that circumscribes the inner cylindrical member. The inner magnets are stacked on top of one another in an axial direction and include a first set having a first polarity alternately arrayed with a second set having a second polarity. The outer magnets are stacked on top of one another in the axial direction and include a first set having the first polarity alternately arrayed with a second set having the second polarity. Each inner magnet in the first set is radially aligned with an outer magnet in the second set and each inner magnet in the second set is radially aligned with an outer magnet in the first set to provide an attractive electromagnetic field between the magnets that passively absorbs axial displacement between the inner and outer cylindrical members.

Abstract: A coil is used for a stator of a motor. An axial direction that is a direction in which an axial center of the motor extends is used to intersect with a gravity direction. The coil is formed by winding a conductive wire having a quadrangular cross section and stacking the conductive wire n turns (n is an integer of 2 or more). The coil includes coil ends at both ends in the axial direction. In one coil end, a k-th turn (k is an integer and 1≤k≤n) is higher than other turns, and the k-th turn is positioned on a lower side in the gravity direction with respect to one another turn.

Abstract: A coil includes: a strand-wound body configured with stacked n turns of a wound strand that is made of a conductor and has a quadrangular cross-section, where n is a natural number; and an insulating resin covering a surface of the strand-wound body. An i-th turn, where i is an integer and 1≤i≤n, has a quadrangular ring shape having four side portions, and in the i-th turn, the insulating resin covers a surface of each of the four side portions. In the first to n-th turns, the insulating resin is continuously and integrally formed.

Abstract: A rotor for an electrically excited drive machine includes: a coil per rotor pole with, in each case, one first energizable coil unit, and a rotor core for holding the coils of the rotor poles. The coils have, in each case, at least one second energizable coil unit per rotor pole. The rotor has an interconnecting unit which is designed to interconnect the at least two coil units per coil in a manner which is dependent on an operating point of the electric drive machine in order to set the number of windings of the coil, and in order to electrically connect the coils of the rotor poles for configuring a rotor winding with an overall number of windings which is dependent on the numbers of windings of the coils.
