When the coil is not energized, the magnets fall away. [Adrian] demonstrates the actuator under the control of an Arduino, which switches power to the coil to move it up and down. He also notes ...

[Carl Bugeja] has taken the idea and in a sense turned it upon its head with his flexible PCB actuator. Now the line of electromagnets are the moving part and the magnetic object the stationary one.

The compact robot operates using an electromagnetic actuator, cantilever, and four-bar linkage system. The cantilever moves when alternating current is applied to a coil, which causes the magnet ...

This module looks at the topologies for, design of, and characteristics of permanent magnet electrical machines. It will look at these machines from the types of magnets employed, electromagnetic ...
