    • In order to facilitate the automated assembly of an electric motor, all of the major components and sub-assemblies thereof are successively brought together in one axial direction. Such major components of the motor include a first cylindrical case, preferably of aluminum, having an end wall at only one end so as to slidably receive, through its other open end, a second magnetic cylindrical case which is relatively shorter than the first case and which opens in the same axial direction for receiving and housing a cylindrical magnet, a rotor assembly insertable through the open end of the second case and including a shaft with a rotor and commutator thereon, a brush base insertable in the open end of the first case so as to bear against the open end edge of the second case and carrying brushes at one side to engage the commutator and a frequency generator at its other side, and a lid member carrying a central thrust bearing for engagement by the respective end of the shaft when the lid member is engaged with the open end of the first case for closing the latter and for bearing against the frequency generator.

    • By enlarging a range, in which an insertion and extraction port is opened, optical disks as stored are made easy to turn over to enable readily retrieve the optical disks as stored. A storage casing includes a bottom plate, a front plate provided on the bottom plate through a first hinge composed of a first bent portion along a first side of the bottom plate, a back plate provided on the bottom plate through a second hinge composed of a second bent portion along a second side opposed to the first side, and a pair of side plates provided on the back plate. When the front plate turns through the first hinge, it turns until engaging parts of turning pieces of the front plate engage with first turning restriction portions, and when the back plate turns through the second hinge, it turns until restriction portions of the side plates engage with second turning restriction portions. The front plate and the back plate are opened outward to enlarge an insertion and extraction port.

    • In a DC brushless motor including a rotor assembly having permanent magnets and a stator assembly having coils arranged in the magnetic field generated by the permanent magnets of the rotor assembly, with the energization of the coils being controlled so as to impart a rotational torque to the rotor assembly; the permanent magnets of the rotor assembly are flat and are attached to a rotor yoke, which can be constructed as an octagonal prism, to provide a path for the magnetic flux emanating from the magnets and to support the flat magnets so that the latter form substantially a regular polygon in cross section. The magnets can be arranged with their poles in a north-south-north-south sequence against flat side walls of the rotor yoke to provide a flux density pattern that is substantially sinusoidal. Alternatively, the flat magnets can be arranged so that magnets of like polarization are disposed on either side of selected corners of a polygonal rotor yoke, thereby providing a flux density pattern that is substantially trapezoidal or rectangular.
