In an armature, a busbar unit includes at least first-, second-, and third-phase busbars electrically connected to respective first-, second-, and third-phase armature windings. The first-phase busbar serves as a lowermost busbar in the axial direction, the second-phase busbar serves as an intermediate busbar stacked over the lowermost busbar in the axial direction, and the third-phase busbar serves as an uppermost busbar stacked over the intermediate busbar in the axial direction. A resin member of the busbar unit covers the lowermost busbar, intermediate busbar, and uppermost busbar stacked in the axial direction, so that the lowermost busbar, intermediate busbar, and uppermost busbar are integrated to constitute a busbar stack. A protrusion member is mounted to the intermediate busbar and protruding radially outward from the intermediate busbar. At least part of the protrusion member is located to be nonoverlapped with the uppermost busbar and the lowermost busbar.

The invention relates to an electromagnetic energy converter which comprises at least one magnetic circuit capable of inducing a variation in the magnetic flux through a conductive coil (200). In this respect, the magnetic circuit comprises a yoke (300) laid out to pivot around an axis of rotation between a first P1 and a second P2 equilibrium position stabilised, respectively, by a first fixed magnet and a second fixed magnet.

Also, the two magnets are laid out such that the stabilisation of the yoke (300) according to one or the other of the first P1 and second P2 equilibrium positions enable the circulation of a magnetic flux in the conductive coil (200), respectively, along a first direction and a second direction opposite to the first direction.

The present invention relates to an interactive electromagnetic apparatus, which includes an acting magnet assembly, a conducting magnet assembly parallel with the acting magnet assembly, an induction coil assembly arranged between the acting magnet assembly and the conducting magnet assembly, and an induction switch module, in which the acting magnet assembly includes at least two magnets arranged to space from each other. These magnets have magnetic poles face the induction coil assembly. The adjacent ones of the magnets are arranged to have opposite magnetic poles face each other. The conducting magnet assembly includes at least two magnets arranged to space from each other. These magnets have two ends having magnetic poles parallel with a moving direction. As such, the induction coil assembly generates a reverse magnetic resistance force at only one end thereof. Through a switching operation of the induction switch module, an opposite end of the induction coil assembly generates a forward magnetic assistance force, so that, compared to the prior art, it is possible to effectively reduce loss of kinetic energy and speed up operation to achieve a purpose of greatly increase energy conversion rate.
