Linear proportional solenoid |
摘要 |
A solenoid device is provided having a permanent magnet mounted directly on the polepiece at the core gap to provide an initial magnetic flux through the polepiece and to focus the induced magnetic flux additionally supplied upon actuation of the solenoid. The magnetic flux through the polepiece continues across the core gap and into an armature which is supported by linear rate springs and spaced from the housing by side gaps. A coil device is mounted about the polepiece to provide induced magnetic flux in response to the applied electrical current input. The polepiece is adjustable within the housing to establish various core gap distances. The side and core gap dimensions within the magnetic flux circuit are proportioned relative to each other to maintain constant magnetic permeance about the circuit during solenoid actuation.
