摘要:
The rotor 11 of an axial gap type motor 10 is provided with a plurality of main magnets 41 respectively magnetized in an axial direction of a rotational axis and disposed at predetermined intervals in a peripheral direction, a plurality of yokes 42 structured by a laminated member 71 produced by winding a tape-shaped electromagnetic steel plate 60 and respectively disposed on both sides of the main magnets 41 in the axial direction, and a rotor frame 30 made of a die-cast alloy and including a plurality of ribs 31 respectively interposed between the main magnets 41 adjoining each other in the peripheral direction and extending in the radial direction, and an inner cylindrical portion 32 and an outer cylindrical portion 33 respectively formed on the radially inner side of the ribs 31 and on the radially outer side of the ribs 31. According to this structure, the yokes structured by the wound laminated member and the rotor frame can be firmly unified with each other, thereby being able to secure such rigidity that can withstand a centrifugal force generated due to the rotation of the rotor and a magnetic suction force given from the stator.
