  • Dual pole dual bucking magnet linear actuator
    Patent number: 10958149
    Abstract: A linear actuator includes dual bucking magnets, dual pole pieces, and dual spacers. The linear actuator includes a coil-and-housing assembly disposed around a magnet assembly. The magnet assembly includes two bucking magnets sandwiched around a central magnet. The central magnet and the bucking magnets may be separated by spacers. A housing is disposed around the magnet assembly. Between the housing and the magnet assembly, a dual coil is wound in two opposing directions to generate additive forces on the magnet assembly.
    Type: Grant
