摘要： Annular magnets, primarily for motor stators, are centrifugally cast from particulate materials and synthetic plastic materials. Iron particles and ferrite particles stratified during the spin casting procedures so that the former provide an outer stratum that serves as a yoke in the permanently magnetized structure. The anisotropic ferrite particles are magnetically oriented during casting by a rotating center magnet with the aid of bucking magnets that also rotate and serve to confine the field of the center magnet to the cavity area. Apparatus for carrying out the process is disclosed and includes means for introducing the plastic and particulate materials to the mold cavity while the mold is rotating as well as mold arrangements that facilitate material introduction by the creation of reduced pressure conditions in the cavity during the rotation of the mold. Permanent magnets or electromagnets may be used for ferrite particle orientation and compound magnets made from laminated and facially polarized rubber magnetic sections and which are arcuately bent are disclosed.

摘要： A magnetic levitation motor which rotates a rotor in a levitated state with respect to a stator by a direct-current magnetic field and stator windings. The magnetic levitation motor comprises: a direct-current magnetic field generating device (4) which forms a magnetic flux having a radial pattern with an axis at the center in a stator (2) and a rotor (3); a first stator winding (6) for generating a levitation control magnetic flux (5) to control levitation of the rotor (3) in a radial direction; and a second stator winding (7) for generating a rotating magnetic field to rotate the rotor (3). The rotor (3) is provided with a yoke portion (9) and a motor magnet (10) which are opposed to a stator core (8) of the stator (2). A part of a bias magnetic flux (11) and a part of a levitation control magnetic flux (5) form a magnetic circuit directly reaching the stator core from the yoke, thereby increasing a levitation force of the rotor.

摘要： An electric rotating machine and manufacturing method of the same is provided that can securely press-fit magnetic poles against an inner circumference of a yoke with a cylindrical body. By directly contacting a first and second end portions of the cylindrical body and moving the same relatively, the diameter of the cylindrical body widens in the outer radial direction to press-fit the magnetic poles against the inner circumference of the yoke. Thus, the variation of the inner diameter of the magnetic poles that occurs due to the dimensional error in permanent magnet thickness and inner diameter of the yoke is absorbed by the relative movement of the first and second end portions. This stabilizes the fixing force of the magnet, and allows the magnet to be securely fixed to the yoke without excessive stress on the cylindrical body. Furthermore, the displacement of the magnetic poles can be restricted by bending axial ends of the cylindrical body radially outwardly.

摘要： One set of circumferentially juxtaposed axial surfaces of the motor magnets of a wet motor gerotor pump are separated circumferentially by a tunnel device having a central bridge portion radially just clearing the rotating armature and bounded by a pair of leg portions extending radially outwards from the central bridge portion to establish a substantially laminar flow path for the fuel. The tunnel device further spaces the armature relative to the gerotor pump cavity. A vent valve is provided in the outlet housing of the pump. A spring biases a ball valve against an imperfect seat encircling the inlet passage to provide a permanent vent bypass passage therebetween. The spring seats the ball valve against the imperfect seat to permit fuel vapors to vent through the vent outlet passage until liquid reaches the ball valve. The liquid then overcomes the bias of the spring to seat the ball against an outlet seat encircling the outlet passage to close the same.
