The Hollow Core Linear Voice Coil Motors, having a large axial hole throughout the entire coil and body structure are ideal for optical focusing, scanning and other precision positioning applications requiring an axial opening through the motor.

H2W’s latest high precision, high speed custom XY gantry utilizes 0.1 micron resolution encoders for high accuracy and repeatability. The moving coil option reduces moving mass and increases acceleration. The bottom axis uses two voice coil actuators in parallel to double the force and acceleration capabilities. Can be driven with standard DC servo or DC linear amplifiers, and a two-axis programmable motion controller. Each axis is guided by a high precision cross roller linear bearing.

A manufacturer of scientific instruments and laboratory equipment used for applications and research in particle science technology uses DryLin® R linear bearings in its series of physisorption and chemisorption analyzers. The manufacturer replaced recirculating ball bearings, which required frequent maintenance and re-lubrication, and as a result is able to save more than $36,000 per year.
