Abstract
A motor includes a permanent magnet unit at a circumference for providing a plurality of magnetic poles and a rotor disposed inside the circumference to be coaxial with the permanent magnet unit. Such a rotor is constituted of a center core, a plurality of coil cores disposed at the peripheral portions of the rotor and a plurality of concentrated coils respectively mounted on the coil cores. Each coil core is fitted to the center core by sliding along an axial direction of the center core.

An apparatus for manufacturing a motor including a permanent magnet unit disposed at a circumference for providing a plurality of magnetic poles, a rotor disposed inside the circumference so as to be coaxial with the permanent magnet unit, said rotor including a center core disposed coaxially with the center axis of the rotor, a plurality of coil cores disposed at peripheral portions of the rotor, and a plurality of concentrated coils respectively mounted on the coil cores, said apparatus comprising:
- means for holding all the coil cores of said plurality of coil cores at one time disposed in position as peripheral portions of the rotor so that the outer peripheries of the held coil cores are on a prescribed circle, the held coil cores defining an inner periphery;
- and
- means for moving the center core in the axial direction thereof to insert the same into the inner periphery of the held coil cores.
An apparatus for manufacturing a motor including a stator, a rotor disposed inside the stator, said rotor including a center core, a plurality of coil cores disposed at peripheral portions of the center core and a plurality of concentrated coils respectively mounted on the coil cores, said apparatus comprising:
- means for simultaneously holding the plurality of coil cores disposed in the same position as the rotor;
- and
- means for inserting the center core into the inside surfaces of the coil cores.
An apparatus for manufacturing a motor including a permanent magnet unit disposed at a circumference for providing a plurality of magnetic poles, a rotor disposed inside the circumference so as to be coaxial with the permanent magnet unit, said rotor including a center core disposed coaxially with the center axis of the rotor, a plurality of coil cores disposed at peripheral portions of the rotor, and a plurality of concentrated coils respectively mounted on the coil cores, said apparatus, comprising:
- a holder simultaneously engaging and holding the outer peripheries of all of the coil cores of said plurality of coil cores at one time so as to dispose said outer peripheries on a prescribed circle;
- and
- an axially movable member disposed to engage and axially displace the center core to insert the center core into the inner periphery of the held coil cores.
