The electromagnetic assemblies define a plurality of stator poles. The device also includes at least one rotor arrangement supported for rotation about a given rotational axis at a certain range of normal operating rotational speeds. The rotor arrangement has a plurality of rotor poles for magnetically interacting with the stator poles. The rotor poles are supported for rotation about the rotational axis along a circular path. A switching arrangement for controlling the electromagnetic assemblies is configured such that the switching arrangement is able to cause the stator poles of the electromagnetic assemblies to magnetically interact with the rotor poles of the rotor arrangement within a certain range of frequencies. The number of rotor poles is selected to be a number such that the switching arrangement causes the stator poles of the electromagnetic assemblies to magnetically interact with the rotor poles of the rotor arrangement in a way which causes the ratio of the frequency of the device in cycles per second relative to the revolutions per minute of the device to be greater than 1 to 4 during the operation of the device.

Abstract: In an electric linear motor, the stator coils are arranged in a line, and the field they produce advances along that line driving the translator along with it. None of the known linear motors can provide all of very high speed, low force, long travel, high linearity and very low moving mass; the present invention proposes an answer in the form of a mechanism that applies motive, displacing force not primarily in the direction along with translator movement is desired but instead approximately at right angles to that direction, the translator being nullsqueezednull out like a cherry pip squeezed between finger and thumb. The invention suggests a linear motor comprising a linearly-extensive stator supporting a translator, the stator providing in operation a squeezing force across the translator in a direction approximately orthogonal to the line of stator, and the translator either having along its movement direction a slightly tapered profile or being mounted on the stator by force-transmitting bearings that, when squeezed, deform to become slightly tapered, the effect being to produce a resultant force on the translator that is along the line of the stator.

Abstract: The brushless motor according to the present invention is small in overall height without deterioration of the rotational accuracy. One of a pair of bearings is interposed between the base plate and the rotor and located on the radially outside of the other one of the bearings. A plurality of receiving holes is formed on the base plate to correspond to the teeth of the stator core to provide an axially space for respectively accommodating coils wound around the stator core. Thus, in spite of the motor having such a small axial clearance between the base plate and the rotor, sufficient amount of winding of coil is ensured. The receiving holes are closed from the outside of the motor with a sheet member and an adhesive is filled therein for fixedly securing the coil of the stator. The adhesive further acts as a damper to absorb magnetic vibration generated at the stator.

Abstract: A rotating leno forming device includes a leno disk (3) that has leno thread guides (5) therein and that itself forms a part of the rotor (2) of an electromagnetic drive arrangement. In order to achieve a very compact structure, the components are so arranged to achieve an axially directed magnetic flux between the rotor (2) and an electromagnetic stator (10) arranged in the housing (8). A rolling contact bearing rotatably supports the leno disk (3), with a first bearing race (6A) connected to the housing (8) and a second bearing race (6B) connected to the leno disk (3). Permanent magnets (7) are arranged on an annular ring surface (3A) of the leno disk (3) extending along a radial plane, so as to face the electromagnetic stator (10) across an air gap (11) that extends on a radial plane. The thread guides (5) in the leno disk (3) face the stator (10) so that the leno threads (13A, 14A) constantly move through the air gap (11) preventing the accumulation of lint or fibers therein, during operation of the device. An iron yoke ring (3B) may be arranged to rotate with the leno disk (3) or to remain stationary with the stator (10), so as to provide a magnetic return or back circuit.

Abstract: A spindle motor for high speed hand tools includes a rotor and a sleeve that is journaled about the rotor. A pressure generating mechanism creates sufficient air pressure in a clearance between the rotor and the sleeve to form a pressurized air film in the clearance when the spindle motor is in normal operation. A plurality of armature coils and a plurality of magnetic sensors for detecting magnetism of magnetic poles in the rotor are provided on the outer surface of the sleeve. The rotor has a field magnet with multiple magnetic poles. The sleeve is formed of a ceramic material whose dielectric constant is 10 or lower. The pressurized air film created by the pressure generating mechanism is sufficient to radially support the rotor so that the rotor does not significantly contact the sleeve during normal operation of the spindle motor. The armature coils cooperate with the field magnet to rotate the rotor by the magnetic interaction between magnetic fields formed by the armature coils and the poles of the field magnet. The excitation of the armature coils is controlled at least in part by signals provided by the magnetic sensors.
