摘要： The present invention provides a rotary electric machine that can achieve prompt restarting and that can also reduce eddy current loss by reducing eddy currents that flow through an outer circumferential surface of a boss portion of a pole core due to the changes in flux in field magnetic flux build-up during starting to enable prompt field magnetic flux build-up in response to a restarting command.
In a rotary electric machine according to the present invention, a first pole core body (17) and a second pole core body (21) are produced using solid cores, and first slits (25) are formed on outer circumferential surfaces of a first boss portion (18) and a second boss portion (22) at a uniform pitch in a circumferential direction so as to have groove directions oriented in an axial direction to disrupt pathways of eddy currents that flow on the outer circumferential surfaces of the first boss portion (18) and the second boss portion (22).

摘要： A power generator with high power-to-volume ratio includes a plurality of silicon steel plates and air gaps or plastic plates, which are alternately arranged to form adjacent magnetic paths of a stator and a mover or a rotor of a power generator and which have intervals (which are defined by thickness or width of the silicon steel plates or the air gaps or the plastic plates) that are set to be very small, whereby when the mover or the rotor take a movement or rotation by one interval, magnetic flux induced in a magnetic path of the stator around which an induction coil is wound changes magnitude and direction thereof so that through quick changes, the induction coil induces a higher voltage and thus significantly increases power-to-volume ratio of the generator.
