  • Patent number: 6179023
    Abstract: An air blower comprises a first unit having means for producing compressed air and a reservoir for storing the compressed air and a second unit including a portable storage tank for holding compressed air, and means for releasing the compressed air from the storage tank. Means for charging are provided whereby compressed air in the reservoir of the first unit is transferred to the storage tank of the second unit.

  • Patent number: 5191256
    Abstract: A rotor for an interior magnet rotary machine, such as motors and generators, is mass produced by forming an elongated structure. This structure has channels in the periphery thereof which are parallel to the longitudinal axis of the structure. The elongated structure is cut into rotor frames of a predetermined length having channels extending from one end to the opposite end thereof. Magnets are placed in the channels. Pole pieces may be placed on the magnets in the channels.The interior magnet rotary machine produced by this method has a rotor of a structure made of a rotor frame with channels extending from one end to the opposite end, and at least one magnet in a respective one of the channels. Thus, an efficient, low cost, mass producible, and easily assembled rotor for an interior magnet rotary machine is provided.

  • Patent number: 4757224
    Abstract: A full flux reversal variable reluctance machine is disclosed. The stator includes a plurality of poles and electrical windings surrounding a portion of the stator. The rotor comprises main and shunt components that have alternate sections of high and low magnetic permeability. The shunt and main components are magnetically isolated, and the sections of high and low magnetic permeability for one component are complementary to the sections on the other component. Variations in flux magnitude and direction are induced in the stator without reversing the flux direction in the rotor.

  • Patent number: 4639626
    Abstract: A variable magnetic reluctance generator is disclosed generally comprising a stator having pairs of spaced magnetic poles of opposite polarity. Like polarity poles are adjacent one another to define a gap having all poles of the same polarity on the same side, and permanent magnet means provide an essentially uniform magnetic field intensity along the length of the gap. The opposite polarity poles are connected by a magnetically permeable path that is surrounded by a stator winding. The rotor has alternating segments of high and low magnetic permeability and these segments move through the gap between the opposite polarity poles, which changes the magnetic permeability between them. This causes variations in the magnetic flux in the magnetically permeable path, which induces an electrical current in the surrounding stator winding. Output voltage may be controlled by auxiliary field coils on the stator or by other means.

  • Patent number: 4571528
    Abstract: An electromagnetic rotary motor including a stator means, a rotor means and an electronic control means for inducing an electromagnetic field. The stator means includes a permanent magnet means having pole faces that define a gap between them with a generally uniform magnet flux density thereacross. The gap has an entrance section, an exit section and a generally curved longitudinal path extending from the entrance section to the exit section around a transverse axis. The magnetic flux density changes as one moves from the entrance section to the exit section as a function of arc degree position around the transverse axis. The rotor means includes a predetermined number of permanent magnets disposed radially outwardly from the rotor axis. These rotor magnets are disposed substantially within the gap and the magnetic field of each rotor magnet interacts with the magnetic field of the stator magnets through repulsion or attraction.
