Precision two-axis direct drive

This two-axis, precision positioning system from BEI Kimco uses a direct linear magnetic drive based on voice coil actuators. It achieves sub-micron positioning with acceleration rates of 50g or more, significantly increasing the throughput of industrial processes.

Voice coil actuators are available in a range of displacements up to 100mm, and with force capabilities of up to 1100 Newton. The direct drive technology eliminates rotary motors, gearheads and leadscrews and has infinite resolution without hysteresis, cogging or detents.

Used extensively in the semiconductor industry for wire bonding, inspection or packaging machines, this direct drive technology is now seeing applications in medical, factory automation and electro optical equipment.
