The electromagnet unit includes a electromagnet element and a main body.
The actuating drive has a first electromagnet (112) and a second electromagnet (114) that is placed at a given distance to the first electromagnet.
The lower case unit (10) preferably accommodates an electromagnet alternatively selected from an electromagnet (30b) exclusively for direct current and an electromagnet (30a) exclusively for alternating current.
A switchable current source (43) is connected to the first and second electromagnets such that the first electromagnet (37) repels the second electromagnet (39).
Each of the housing member includes an upper electromagnet, and a lower electromagnet separated from the upper electromagnet.
A conditioning electromagnet temporarily magnetizes the metals.
An apparatus (100) for an electromagnet is disclosed.
An omnidirectional electromagnet (100) is disclosed.
One embodiment contains a top electromagnet in a top layer of a bio-disc and a bottom electromagnet in a bottom layer of the bio-disc.
A piston can be displaced in a cylinder, especially by an electromagnet, wherein a permanent magnet or likewise an electromagnet can be arranged in the piston.
In the corresponding circuit arrangement, a time stage (102, 10n) is disposed between the excess-current tripping device and the second tripping magnet and each following tripping magnet (92...9n).
A permanent magnet and solenoid system operate the shutter blades.
The piston can also be displaced by compressed air.
Whether the on-off of the solenoid valve is reliable is exactly identified, and the safety risk caused by the leak of the solenoid valve therefore can be avoided.
