Abstract:
A magnetic gear magnetically connecting a plurality of carriers rotatable relative to one another, comprising;a first carrier and a second carrier; a plurality of magnetic poles disposed in a circle on each of the first carrier and the second carrier, with a gap separating adjacent magnetic poles, the plurality of magnetic poles being arranged in an alternating positive pole and negative pole configuration; and a third carrier having at least two pairs of flux-carrying connecting pieces, wherein said flux-carrying connecting pieces are arranged so that, in a first rotational position of the carriers, a first section of the first pair of flux-carrying connecting pieces faces the gap between two adjacent magnetic poles of the first carrier, and a second section of the first pair of flux-carrying connecting pieces faces the gap between two adjacent magnetic poles of the second carrier, and wherein, in the first rotational position of the carriers, a first section of the second pair of flux-carrying connecting pieces faces a magnetic pole of the first carrier, and a second section of the second pair of flux-carrying connecting pieces faces a magnetic pole of the second carrier.
