    Thank your for your interest...I spoke with a professional in my city and they were skeptical about the performance of a beryllium copper constant force spring. I suggested I prototype with a steel spring and then once I settled on the correct configuration, we could design a similar version in...

    Counterbalance for vertical stage...non-magnetic application

    I am designing an xyz positioning system in a non-magnetic application. I am using linear piezomotors on all axes (www.nanomotion.com). I am concerned about the z-axis. My reading tells me that I should ideally counterbalance the weight on this axis in order to cancel the forces acting on the...
