Embodiment Construction

[0009] exist figure 1 Among them, three high-strength magnets (4), two middle magnetic conductive plates (5) and two outer magnetic conductive plates (6) are connected in series at intervals to form a vibrator. The thickness of the middle magnetic conduction plate (5) is greater than the thickness of the outer magnetic conduction plate (6), and two adjacent high-strength magnets (4) are adsorbed on both sides of the middle magnetic conduction plate (5) oppositely with the same pole. There are coil slots on the coil holder (2) corresponding to the middle magnetic plate (5) and the outer magnetic plate (6), and the built-in electromagnetic coil (1), the winding direction or wiring design of the electromagnetic coil (1) The current directions of any two adjacent electromagnetic coils (1) must be opposite. The coil holder (2), the electromagnetic coil (1) and the magnetically permeable outer cylinder (3) are cemented into a whole. The leaf spring (8), the through-bolt (10) and t...

Abstract

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.

Description

Technical field [0001] The invention relates to the mechanical field, in particular to a series-connected high-energy electromagnetic actuator. Background technique [0002] At present, there are high-energy electromagnetic actuators used in active vibration reduction systems, such as an electromagnetic actuator developed by CSA Engineering, Inc. in the United States, which mainly consists of a set of high-strength magnets, two magnetic plates, and two electromagnetic It consists of a coil, a magnetically conductive outer cylinder and two sets of leaf springs. Magnetic plates are attached to both ends of the magnet to form a vibrator. The two electromagnetic coils are wound in opposite directions and respectively glued to the inner walls of the two ends of the magnetic conduction outer cylinder, and the positions are opposite to the magnetic conduction plate. Leaf springs and through-hole bolts connect the vibrator and the magnetically conductive outer cylinder from both e...
