Frequency Compensation with Copper ring in a Shaker

[Bahram Naseri]

I've designed a electromagnetic vibration shaker but I've problems at high frequencies(200 Hz and upper) and I've heard that I can compensate it by a Copper ring,please comment me...Bahram

What problems are you having? How is your system set up? How would the copper ring compensate for your problem? You'll definitely need to add some information before you get helped.

Hello Bahram,

Thank you for sharing your design and the challenges you are facing with high frequency vibrations. Frequency compensation with a copper ring is a common technique used in shakers to improve the performance at higher frequencies.

Copper rings are commonly used as a form of passive vibration control in electromagnetic shakers. They are placed around the coil of the shaker and act as a short circuit for high frequency currents. This helps to reduce the impedance of the shaker at high frequencies, allowing it to operate more efficiently and with better control.

The use of a copper ring can also help to reduce the heating of the coil, which can occur at high frequencies and cause the shaker to malfunction. By reducing the impedance and increasing the efficiency of the shaker, the copper ring can help to improve the overall performance and reliability of your design.

However, it is important to note that the use of a copper ring may not completely solve the problems you are facing at high frequencies. It is still important to ensure that your shaker is properly designed and calibrated for the specific frequency range you are working with. Additionally, other factors such as the type and quality of materials used in the construction of the shaker can also affect its performance at high frequencies.

I would recommend consulting with a vibration expert or conducting further research to fully understand the benefits and limitations of using a copper ring in your specific design. I wish you the best of luck in your project and hope that this information has been helpful to you.
