摘要： A motor for driving a magnetic disk in which the rotational center of the magnetic disk is a fixed shaft. The motor has a frame, a shaft formed integral with the frame, an armature, a bearing provided on the shaft, a hub to which a magnetic disk is securable, a magnetic sealing material arranged in the vicinity of the bearing and a magnetic material opposed to the sealing material. A magnetic seal is arranged between the magnetic sealing mateial and the magnetic material. The frame, the shaft, the hub and the magnetic disk are formed of aluminum, so that changes in temperature will not adversely affect motor performance due to the differences in thermal expansion of these motor parts. The magnetic material is in the form of a sleeve which enables the motor to be magnetically sealed and prevents foreign matter in the motor from reaching the magnetic disk.

摘要： A drive magnet unit is fixedly mounted on the inner cylindrical surface of the cylindrical portion of a rotor yoke which is fixedly mounted on a hub, in such a manner that the drive magnet unit confronts a stator core. The rotor yoke has an annular portion along its open end. The rotor yoke has a curved portion along the open end which forms a gap with the outer cylindrical surface of the drive magnet unit. The annular portion is sheared along its base, thus forming a shear plane. The inner surface of the bottom of the rotor yoke, and the inner cylindrical surface of the cylindrical portion of the rotor yoke form a right-angled portion with which the right-angled outer edge portion of the drive magnet unit is engaged. The peripheral surface of the right-angled portion defines a through-hole in the bottom which is engaged with the hub. The gap is filled with adhesive, to fixedly secure the drive magnet unit to the rotor yoke.

摘要： A current feed means is connected to an armature coil of a motor. Current is fed from the current feed means to the armature coil while the frequency of the current is gradually varied from a preset frequency to another preset frequency, thereby to vibrate the motor. The amplitudes of the frequencies are measured by a frequency analyzer means, which is brought into contact with the motor. The frequency at which the amplitude of the vibration of the motor is peaked indicates the natural frequency of the motor.
