Abstract
The rotorof an axial gap type motoris provided with a plurality of main magnetsrespectively magnetized in an axial direction of a rotational axis and disposed at predetermined intervals in a peripheral direction, a plurality of yokesstructured by a laminated memberproduced by winding a tape-shaped electromagnetic steel plateand respectively disposed on both sides of the main magnetsin the axial direction, and a rotor framemade of a die-cast alloy and including a plurality of ribsrespectively interposed between the main magnetsadjoining each other in the peripheral direction and extending in the radial direction, and an inner cylindrical portionand an outer cylindrical portionrespectively formed on the radially inner side of the ribsand on the radially outer side of the ribsAccording 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.
