Abstract: A motor including a plurality of temperature monitoring sensors is described. The temperature monitoring sensors are attached to stator coils and stator winding phases of the motor. The temperature monitoring sensors include a face side and a lead side which are positioned along the stator winding phases to properly monitor the motor temperature prior to insertion of the winding phases into a stator iron.

Abstract: An electric motor to be used with a termination network that is integral with the motor and connected to the motor's supply motor lines for reducing voltage between a motor terminal and a transmission line connected to a pulse width modulated drive when high frequency surges, or spikes, are present. Further, the termination network will not adversely effect sinusoidal performance ratings of the motor on which it is used. In addition, since the termination network is integral with the motor, the termination network assembly can be installed during assembly of the motor, thus lowering the cost of installation.

Abstract: A threadless coupling for pressurized systems includes a nut member and a mating member. The nut member has a first axial end for attachment to the pressure sensitive control, a second axial end configured for engagement with the mating member, and a housing extending between the first axial end and the second axial end. The housing is configured for locking engagement with a pair of retaining tabs extending from an outer surface of the mating member. Each mating member retaining tab engages a corresponding seating surface and step surface of the respective housing opening so that relative axial and rotational movement of the nut member and mating member is prevented.

Abstract: An endshield assembly for an electric motor is described. The endshield assembly includes a metal endshield, a bearing assembly, and an injected molded metal center housing that couples the bearing assembly to the metal endshield. The bearing assembly includes a cylindrical housing having an outer surface. The center housing includes a cylindrical wall having an inside surface and a plurality of projections extending from the inside surface of the cylindrical wall. The projections are positioned around the circumference of the inside surface of the center housing to engage the outer surface of the bearing housing. The projections are staggered about the center housing circumference so that every projection contacts the outer surface of the bearing housing on an opposite side of a bearing housing circumferential centerline than an immediately adjacent projection.

Abstract: An electronic cam servo apparatus uses a digital servo controller to perform motion equivalent to a mechanical cam. The control apparatus has one data table representing a characteristic of a mechanical cam and utilizes a data interpolation and the first derivative of a cam position profile to determine position and velocity commands to drive a servo motor which performs motion equivalent to a mechanical cam. Alternatively, the control apparatus uses the first cam specific data table to determine the position, velocity and torque/current command to drive a servo motor. The apparatus may additionally use a second data table representing varying cam load to obtain a more accurate torque/current command correction.

Abstract: A bearing system includes a housing with first and second relief cuts, and a bearing assembly that includes an inner race and an outer race. An adjust screw contacts a preload spring positioned adjacent the outer race. The preload spring exerts a force on the outer race. The outer race includes a first and second edge, and a connecting portion. The first and second edges are positioned adjacent the first and second relief cuts respectively. The connecting portion contacts a bearing bore surface while the first and second edges of the outer race do not contact the bore surface.

Abstract: A refrigerator condenser fan motor enclosure including a base and a cover is described. The base and cover forming a top and a bottom of the enclosure which protects the refrigerator condenser fan motor from exposure to air borne contaminants. The base includes a first leveled step and a second leveled step which are mechanically connected to stator laminations of the condenser fan motor, a ground terminal for the condenser fan motor, and mounting lugs which allow the enclosure to be mounted onto a refrigerator. The cover is attached by tabs which are inserted into slots in the base.

Abstract: A bearing assembly including a bearing member with a passageway therethrough at least in part defining a cylindrical journaling surface having a central axis and a preselected axial length is described. A partial circumferential or spherical surface on at least a part of a peripheral portion of the bearing member extends generally coaxial about the cylindrical journaling surface. A bearing seat supports the bearing member at a generally circular line of engagement defining an imaginary plane extending generally perpendicular to the central axis through the mid-point of the preselected axial length of the cylindrical journaling surface.
