Provided are a motor and an optical apparatus each including: a rotatable
rotor having a cylindrical magnet; a first coil; a first outer magnetic
pole portion which is disposed at a center portion of the first coil and
which is opposed to an outer circumferential surface of the magnet within
a first predetermined angle range; a second outer magnetic pole portion
which is adjacent to an outer circumference of the first coil and which
is opposed to the outer circumferential surface of the magnet; a first
inner magnetic pole portion which is adjacent to the outer circumference
of the first coil and which is opposed to an inner circumferential
surface of the magnet; a second coil; a third outer magnetic pole portion
which is disposed at a center portion of the second coil and which is
opposed to the outer circumferential surface of the magnet within a
second predetermined angle range; a fourth outer magnetic pole portion
which is adjacent to an outer circumference of the second coil and which
is opposed to the outer circumferential surface of the magnet; and a
second inner magnetic pole portion which is adjacent to the outer
circumference of the second coil and which is opposed to the inner
circumferential surface of the magnet. Accordingly, there are provided a
motor and an optical apparatus which realize higher output without
impairing miniaturization.
