Steven Roger Huard has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cornering linear motor
    Patent number: 10734879
    Abstract: A linear motor includes a forcer having a plurality of teeth spaced apart along a longitudinal axis of the forcer. At least some teeth arranged about a longitudinal center of the forcer are dimensioned different from at least some other teeth arranged at ends of the forcer distal from the longitudinal center. The teeth may be dimensioned to define a pocket relative to the longitudinal axis of the forcer.
    Type: Grant

  • Linear motor with magnet rail support, end effect cogging reduction, and segmented armature
    Patent number: 6919654
    Abstract: A linear motor is provided which includes members for engaging a magnet rail to prevent bending of the magnet rail. Such members may include a wheel or sliding block, for example. The members exert a force proximate an upper edge of the magnet rail to counter potential bending of the magnet rail during operation of the motor, and thereby avoid substantial variations in the air gaps. Furthermore, an armature yoke is provided which includes at least one partial tooth at one end of the armature yoke for reducing an end effect cogging of the linear motor armature in relation to a magnet rail along which the armature will run. In addition, an armature yoke is provided which includes multiple segments which are held end-to-end via fasteners. Such fasteners may serve as part of the magnetic flux path. A support strip may be provided to reduce bowing.
