Title:
双安定磁気ラッチ
Document Type and Number:
Japanese Patent JP4516075
Kind Code:
B2
Abstract:
A magnetic bi-stable latch with an upper stator and a lower stator, a rotor between the upper stator and lower stator and adapted for rotation between a first latched position and a second latched position. Each of the stators is a magnetic assembly having at least two inner poles and two outer poles of magnetic material, and at least one stator further having a coil disposed in relation to the inner pole and the outer pole to form an electromagnet. The stators are positioned such that the outer poles of the upper stator align with the inner poles of the lower stator and the inner poles of the upper stator align with the outer poles of the lower stator. The rotor has permanent magnets mounted thereon such that in the first latched position the permanent magnets are aligned with poles of the upper and lower stators.
