A single air gap permanent magnet electric motor is provided with field magnets formed as thick annular segments concentric with the axis of rotation of a solid non-magnetic cylindrical armature. The field magnets are magnetized radially to the axis and have oppositely polarized pole faces facing the axis. The ratio of the thickness to the inner diameter of the annular segments is maintained within a defined range to provide for a high magnetic flux density across the single air gap.

This disclosure relates to electric motor/actuators and in particular to an electric motor/actuator for driving a sewing machine and operating sewing machine controls regulating, for instance, the position coordinates of the resulting stitches formed by the sewing machine. The electric motor includes multiple non-magnetic armatures having commutated windings rotatable in a single air gap formed between opposing permanent magnets having their opposed polarized poles facing said armatures and wherein individual ones of said armatures are capable of different output functions free of significant interaction with others of said armatures.

A position sensing device is disclosed including an assembly of a Hall effect generator element shiftably supported relatively to a permanently magnetizable element. Each such Hall effect generator element being randomly chosen from an inventory of parts having wide tolerance limits of Hall effect output under like magnetic flux influence; and each magnetizable element from an inventory having a widely varying magnetic capability after exposure to like magnetizing influence. The magnetization of the magnetizable element of each such assembly being imparted thereto under control of the Hall effect output of the specific Hall effect generator in the assembly with the result that every position sensing device so assembled can be made to produce substantially identical Hall effect output in each relative position of said elements.

This disclosure relates to means for preventing the reciprocating needle of a sewing machine from operating in a zig-zag mode when a straight stitch throat plate means is positioned on the work bed surface. A latching means is provided for selective interconnection between the zig-zag jogging mechanism and the needle mechanism with said latching means being responsive to movement of the presser mechanism for unlatching the latching means. A locking mechanism is also provided to lock the latching mechanism in an unlatched position.

A circuit which limits the maximum permissible speed of a sewing machine motor when specific stitch patterns are selected. Electronic signals from a means for sensing the selected stitch pattern are analyzed by the circuit to control the operation of a relay which connects a resistance in series with the sewing machine motor to reduce the maximum speed at which the drive motor may be operated.

A linear motor for use, for example, in sewing machines for controlling needle vibration as to amplitude and/or fabric feed both in magnitude and direction, said motor comprising a frame having an internal central pole piece spaced intermediate two permanent magnets of the high energy product type which are attached to the frame, the central pole piece providing supporting means for movable coil member integrally formed with connecting arms pivotally fastened to an actuator arm carried on a pivoted potentiometer shaft. The permanent magnets are secured through their own magnetism to the frame and are each locked in proper orientation by a non-metallic retainer which is locked to the magnet and additionally formed with a closure panel, said closure panels cooperating with the motor frame completely to enclose a compartment for the movable coil member effecting both a minimum external leakage field and a dust proof unit.

This disclosure relates to a direct drive feed mechanism for sewing machines which is driven by an electronically controlled reversible electric motor and includes a linearly operable feed dog mechanism which is compact in structure and modular in nature. More particularly, the disclosure of this invention relates to a novel four motion feed mechanism for a sewing machine wherein reciprocating feed motion of the feed dog is initiated by a reversible electric motor which in turn is controlled by electronic logic means. Because of the novel structure of this invention, the feed of the fabric by the machine can be readily controlled so as to be capable of producing a plurality of programmed feed patterns.

A sewing machine, wherein a stitch controlling instrumentality is positioned during operation of the machine by a motor acting through connecting linkages, is provided with a ring magnet that is connected to said linkages for angular displacement thereby about its axis and with a linear output Hall effect sensor that is disposed within the ring magnet to produce an output voltage proportional to displacement of the stitch forming instrumentality.
