摘要： A device includes an armature, a coil, and a circuit. The armature is configured to move between a close position that electrically couples the armature to a contact and an open position that is not electrically coupled to the contact. The coil is configured to release a voltage configured to de-magnetize the coil, thereby causing the armature to move from the close position to the open position. The circuit is configured to provide reverse driving current to the coil during a period of time when the armature moves from the close position to the open position.

摘要： A system for sequentially interconnecting battery modules of a battery pack is disclosed. The battery pack may comprise first, second and third battery modules. Each of the first, second and third battery modules includes a first power output terminal and a second power output terminal. Each of the first power output terminals is of a first polarity and the each of the second power output terminals is of a second, opposite polarity. The system comprises a control module for providing a control signal to sequentially interconnect the battery modules, a first interconnect controller electrically disposed between the first and second battery modules, and a second interconnect controller electrically disposed between the second and third battery modules. Each of the first and second interconnect controllers includes a contactor comprising a main contact, an auxiliary contact and an actuating coil for closing the respective main contact and auxiliary contact. The actuating coil of the first interconnect controller responds to the control signal to close the respective main contact, coupling the first battery module to the second battery module, and to close the respective auxiliary contact to pass the control signal to the second interconnect controller. The actuating coil of the second interconnect controller responds to the passed control signal from the first interconnect controller to close the respective main contact of the second interconnect controller, coupling the third battery module to the previously connected first and second battery modules.

摘要： An electromagnetic relay includes an electromagnet device, a contactor, and a trip device turning the contactor into an open state in which the contactor opens when an abnormal current flows. The electromagnet device includes a first excitation coil, a fixed element, first and second movable elements, and a permanent magnet. The contactor includes a fixed contact and a movable contact. In the electromagnetic relay, while the permanent magnet causes the first movable element to attractingly contact the second movable element, the fixed element attracts the first movable element due to a magnetic flux generated by the first excitation coil so as to move the second movable element together with the first movable element from a normal position to an attracted position. In the contactor, the movable contact moves, as the second movable element moves, so as to switch between a closed state in which the movable contact contacts the fixed contact and the open state in which the movable contact is removed from the fixed contact. The contactor is turned into the closed state when the second movable element is located at the attracted position. The trip device includes a second excitation coil connected in series to the contactor and a spring for acting a force on the second movable element in a direction away from the first movable element.

摘要： An electromagnetic device includes: a coil configured to generate a first magnetic flux; a fixed member, a movable member configured to reciprocate to separate from the fixed member by a predetermined gap when a current applied to the coil is stopped and move to the fixed member by an attractive force when the current is applied to the coil; and a permanent magnet configured to generate a second magnetic flux between the respective opposed surfaces of the fixed member and the movable member in the same direction as the first magnetic flux. The permanent magnet is attached to at least one of the fixed member and the movable member such that a magnetized surface of the permanent magnet is opposed and exposed to the opposed surface of the other one of the fixed member and the movable member.

摘要： A magnetic latching relay includes a casing containing a coil assembly, an electrically conductive plate and a static plate. A reed assembly is installed on surfaces opposite to the electrically conductive plate and the static plate and includes a reed, a pull-to-disconnect plate installed onto the reed, and a contact formed on the pull-to-disconnect plate. The casing includes a pushing latch latched to the coil assembly. If the relay is connected, the contacts of the reed assemblies of the electrically conductive plate and the static plate will touch each other, or else the pushing latch will be moved axially along the static plate and inserted between the pull-to-disconnect plates of the reed assemblies of the electrically conductive plate and the static plate to separate the contacts, so as to monitor the connected/disconnected status of the relay. An external display device is provided for displaying the connected/disconnected status.

摘要： A switch for an electrical circuit includes a base, a rotatable cam having a first profile and a second profile, a solenoid, a link, and a member comprising a cam follower configured to follow the second profile. A first cycle of the solenoid includes a first energized state and a first de-energized state and the second cycle of the solenoid includes a second energized state and a second de-energized state. A first portion of the link couples to the solenoid, and a second portion of the link movably couples to the first profile of the cam. When the solenoid is in a first cycle, the member moves from a retracted position to an extended position, and when the solenoid is in a second cycle, the member moves from the extended position to the retracted position.

摘要： An electrical contactor has a first terminal having a fixed member with at least one fixed electrical contact, a second terminal, and a busbar connected to the second terminal. Two conductive movable arms are connected to the busbar and have a contact thereon. One arm is biased-closed to contact the fixed electrical contact in the absence of a separating force, and the other arm is biased-open to be spaced away from the fixed electrical contact in the absence of a closing force. The first and second movable arms and the busbar are arranged so that, when the contacts close, contra-flowing current urges the movable arms towards the fixed member to increase a force between the contacts.

摘要： Electromagnetic actuators capable of generating a symmetrical bidirectional force are disclosed. The electromagnetic actuators include a housing made of a ferromagnetic material and a shaft made of a magnetically inert material movable along an axis within the housing. In one type of actuator, captive permanent magnets are arranged on opposite interior end walls of the housing and an electromagnetic coil is mounted on a central portion of the shaft. The electromagnetic coil is capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on the direction of current through the electromagnetic coil. In another type of actuator, captive electromagnetic coils are arranged on opposing inner end walls of the housing, and a permanent magnet is mounted on a central portion of the shaft. The electromagnetic coils are capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on a direction of current through the electromagnetic coils.
