Abstract
An electromagnetic actuator device, the device including an electromagnet including a coil, and a magnetic core including a first portion extending from a front face of the coil, and a second portion extending from a back face of the coil bending back along the coil toward the front face of the coil, and a plate placed such that a first portion of the plate parallels the first portion of the magnetic core and a second portion of the plate parallels the second portion of the magnetic core. Related apparatus and methods are also described.
Claims21
An electromagnetic actuator device, the device comprising:
- an electromagnet comprising:
- a coil;
- and
- a magnetic core comprising:
- a first portion extending from a front face of the coil;
- and
- a second portion extending from a back face of the coil bending back along the coil toward the front face of the coil;
- and
- a plate placed such that a first portion of the plate parallels the first portion of the magnetic core and a second portion of the plate parallels the second portion of the magnetic core.
(canceled)
An electromagnetic actuator device, the device comprising:
- an electromagnet comprising:
- a coil;
- and
- a magnetic core comprising:
- a first portion extending from a front face of the coil;
- and
- a second portion extending from a back face of the coil bending back along the coil toward the front face of the coil;
- and
- a zigzag shaped plate placed such that a first leg of the zigzag shaped plate parallels the first portion of the magnetic core and a second leg of the zigzag shaped plate parallels the second portion of the magnetic core.
A method of operating an electromagnetic actuator, comprising:
- providing electric power to a coil;
- producing a magnetic field within a magnetic core;
- a first portion of the magnetic core, extending from a first face of the coil, exerting a first magnetic attraction force on a first portion of a plate;
- and
- a second portion of the magnetic core, extending from a second face of the coil, exerting a second magnetic attraction force on a second portion of the plate,
- wherein the first magnetic attraction force and the second magnetic attraction force are in a same direction,
- thereby exerting two magnetic attraction forces in a same direction on the plate.
