Series connection type high energy electromagnetic actuator

The vibrator of the actuator consists of the two or more blocks of high tensile magnet, the two outboard magnet plates are the one of more middle magnet plates assembled, according to the desired sequence in series. The thickness of the magnet plates in middle of the vibrator is thicker than the outboard magnet plates. Two magnets with their homopolars face to face clamp the magnet plates in middle. The coil holder, the magnet coil and the magnet outer tube are cemented as one body. The through bolt and the sheet spring connect the vibrator and the magnet outer tube. The shortened magnetic circuit, the reduced magnetic resistance and more magnet plates utilized make the effective turns of the magnet coil increase greatly so as to increase the exciting force of the actuator greatly.
