摘要： Disclosed is an electromagnetic vibratory pump, comprising a first C-shaped winding and a first magnet. The first C-shaped winding comprises a first coil and a first electromagnetizable member. The first coil covers the first electromagnetizable member, which comprises a first main body, a first leg and a second leg. The legs are connected to the first main body, and the distance between the legs is reduced from a first width to a second width from the first main body. The first magnet swings in a circular tangential direction. A point of tangency of the circular tangential direction is configured apart from the first leg and the second leg respectively by a first minimum distance. The first minimum distance is less than a half of the second width. The first magnet is driven by the first magnetic line of force to move in the first circular tangential direction, and the first magnet is driven by the second magnetic line of force to move in the second circular tangential direction.

摘要： The present invention is disclosed by that the power source device is operatively controlled by the switching device to supply AC power to excite the driving coil thereby producing larger electromagnetic effect to obtain actuating force, and after actuation, the power source device being operatively controlled by the switching device is switched to provide DC power output of lower voltage to the driving coil thereby passing smaller current to maintain excitation while required operating characteristics of the electromagnetic actuating device are still ensured.

摘要： An electromagnet system for electromagnetic switchgear, the system having movable and stationary magnet portions, the stationary magnet portion having a pole surface wherein slots are provided for inserting a short-circuit ring. The slots are arranged so that the short-circuit ring may be substituted with a pole plate which extends beyond the pole surface on all sides. The pole plate has an opening which corresponds to the size of the pole surface. The opening is provided with two straps thereacross which can be inserted into the slots. This arrangement permits operation of the electromagnet system in response to AC, as well as DC, excitation.

摘要： A magnetic structure including a coil and yoke includes a bobbin or spool having a coil wound thereon, the flanges at the ends of the bobbin having protruding ribs defining radially extending slots which receive the legs of bundles of U-shaped laminations. The outer corners of the laminations are beveled or chamfered and are retained in position by end plates which have inwardly protruding inclined surfaces positioned to engage the beveled corners, thereby preventing outward radial movement of the laminations. The end plates can then be retained in place by conventional fastener means. The entire assembly can also be spray-coated with plastic. The laminations themselves are not perforated.

摘要： An improved solenoid apparatus for operating valves such as hydraulic/air valves or other mechanical devices including a pressure proof tube which is wholly or partially nonmagnetic and has one end connected sealingly to a stationary core, an armature slidably mounted in contact with the inner face of the pressure proof tube, and a coil assembly comprising substantially a yoke and a coil encompassing the pressure proof tube. A cylindrical magnetic ring enclosing a part of the stationary core and a part of the pressure proof tube in the vicinity of the end face at the attracting side of the stationary core is inserted between the stationary core and the coil assembly the one end of the magnetic ring protruding axially over to the armature side, whereby the solenoid can be used either with alternating or direct current merely by replacing the coil assembly. When the solenoid is connected to an AC power source, there is no need to install a shading coil and therefore, the apparatus is low in cost and reliably endures impact loads.

摘要： A coil is wound on a hollow plastic bobbin and mounted in a U-shaped ferromagnetic frame, there being a pair of aligned bosses on opposite sides of the bobbin bore at one end thereof fitting into cooperating slots in the frame. A ferromagnetic core is axially movable within the hollow bobbin and is urged away from the bottom of the frame by a leaf spring. A compact plastic housing covers the bobbin, coil, and the upper portion of the frame, and electric terminals, mounted in pockets at the top of the bobbin, project through slots in the housing to the exterior. Portions of the bobbin are extruded into openings in the base of the terminals to hold them in place, and a pair of tabs on the bobbin interact with slots in the housing, and posts on the inside corners of the housing form abutments to prevent over-insertion of the tabs in the slots. A hook on the bottom of the frame is shaped to be engageable with an opening in external support elements of differing thickness to facilitate installation. The coil contains a relatively fine gauge wire which acts as a fuse if the buzzer is energized beyond a predetermined time period.
