  • Power Tools With Motor Having a Multi-Piece Stator
    Publication number: 20090021090
    Abstract: A power tool has a motor having a stator made by separately forming pole pieces, return path pieces and field coils. The field coils are placed over necks of the pole path pieces and the return path pieces are affixed to the pole pieces. An armature having an outside diameter of at least 0.625 the outside diameter of the stator is placed in the stator. The field coils may be formed so that they extend beyond pole tips of the pole pieces.

  • Field assemblies having pole pieces with axial lengths less than an axial length of a back iron portion and methods of making same
    Patent number: 7211920
    Abstract: An electric motor, power tool using the electric motor, and method of making the electric motor includes making a stator that includes pole portions that have axial lengths less than an axial length of a back iron portion. Alternatively, or in addition, the pole portions have axially opposed ends that decrease in width. Alternatively, or in addition, the pole portions have dovetail features that are received in corresponding recesses of the back iron portion.

  • Field assemblies having pole pieces with ends that decrease in width, and methods of making same
    Patent number: 7205696
    Abstract: An electric motor, power tool using the electric motor, and method of making the electric motor includes making a stator that includes pole portions that have axially opposed ends that gradually decrease in width. The pole portions may also have dovetail features that are received in corresponding recesses of the back iron portion.

  • Control method and device for a switchgear actuator
    Patent number: 6331687
    Abstract: A current interrupter (4) includes a current interrupting device (4) having at least one movable contact (71); an actuator (8) coupled to the movable contact (71) of the current interrupter (4); a feedback sensor (14) for monitoring movement of the actuator (8); and a control system (12) coupled to the feedback sensor (14) so as to receive information from the feedback sensor (14) concerning the movement of the actuator (8) and for controlling movement of the actuator (8) based on the information. The interrupter (4) further includes a memory (202) for storing a desired motion profile of the actuator (8); and a microprocessor (202) for comparing the movement of the actuator (8) with the desired motion profile and controlling movement of the actuator (8) based also on a comparison of the movement of the actuator (8) with the desired motion profile.
