Abstract
An alternating hybrid excitation assembly and its application to a rotary motor, linear motor and transformer, including: an even number of iron cores and a plurality of magnetic isolation layers arranged between, forming a loop, each core includes one or two notches wherein permanent magnets are inlaid, the two magnetic pole faces are attached to two opposite sides of the notch of the corresponding core, and a gap is reserved between one side face of each magnet and the side edge of the notch of the core; the magnets have opposite magnetic polarity directions, and an excitation coil surrounds the cores. A permanent magnetic potential and an excitation magnetic potential are superimposed to form an alternating hybrid excitation magnetic field, and thus electromagnetic energy efficiency is improved. Further, embodiments of the alternating hybrid excitation assembly applied to the rotary motor, the linear motor and the transformer.
