摘要： Reluctance-based resonant linear motors and methods of operation are provided. An example linear motor includes a spring having a plurality of coils. The linear motor includes a stator coaxially surrounding at least a portion of the spring. The stator includes a plurality of teeth. The linear motor includes a plurality of windings respectively positioned within a plurality of winding cavities respectively formed by the plurality of teeth. The application of electrical energy to the plurality of windings generates a magnetic field that flows through one or more of the coils of the spring. The flow of the magnetic field through the one or more coils of the spring causes the spring to actuate towards a compressed position. An example method includes periodically applying electrical energy to the plurality of windings such that the spring oscillates at a resonance frequency associated with the linear motor.

摘要： A method for forming a magnetic core for the magnetic circuit of a linear-motor compressor suitable for use in a refrigerant system. The compressor includes a conical armature which reciprocates in a complementary air-gap under the influence of an electromagnetic circuit and a pair of linear complementary return springs connected to the armature between the compressor piston and outboard bearing. The electromagnetic circuit includes a pair of abutting convoluted loops of spirally wound magnetic strip material with a conical air-gap fabricated in the area of abutment. The magnetic core is formed by forming a pair of stacks of magnetic strips having diverse lengths, bending each stack to form a generally C-shaped core section having a generally semi-circular air-gap space defined by the ends of the strips, fastening the C-shaped stacks in opposed abutment to form a generally cylindrical air-gap, and then machining the air-gap into the desired conical shape.

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.
