Characteristic
• Energy Transformation and Exchange:Electromagnetic
dampers(EMDs)have the unique ability to provide energy
transformation and exchange between mechanical and electrical
systems.
• Adjustable Damping:EM dampers can adjust the equivalent damping
using a simple switched circuit,making them suitable for
semi-active control applications.
• Self-Powered Capability:Some EM dampers are capable of harvesting
vibrational energy and storing it in a rechargeable battery,which
can then be used to power sensors and microcontrollers in
semi-active control modes,realizing the characteristics of a
self-powered EM damper.
• High Power Output:EM dampers can achieve high power output
levels,making them attractive for energy harvesting applications.
• Constant Damping-Constant Power:EM dampers have the inherent
characteristic of"Constant damping-Constant power,"which is
important for their operation under impact loads.
• Compact and Energy Efficient:The control flux in EM dampers does
not have to travel through high-reluctance permanent
magnets,resulting in a more compact and energy-efficient device.
• Practical Elimination of Negative Stiffness:The use of flux
feedback control in EM dampers can practically eliminate the
actuator negative stiffness,which is an advantage over more
conventional current control.
• Damping Smoothness:The introduction of pneumatic damping in some
EM dampers makes the force–displacement curve smoother and
increases the damping force significantly.
• Vibration Control and Energy Harvesting:EM dampers can serve dual
purposes of vibration control and energy harvesting,providing green
and regenerative energy output.
• Reduced Self-Heating:A part of energy dissipation occurs outside
the EM damper,which may reduce the problems normally associated
with the self-heating of viscous and friction dampers.
