Dual-headed Voice Coil Positioning System by H2W Technologies

Published on May 15, 2013 at 6:05 AM

H2W's dual headed voice coil positioning Stage (VCS15-050-LB-01-MC-2) is a high precision two axis positioning system for high end motion control applications. 

Each head that rides on a common linear rail is driven by an NCC moving coil type linear actuator, and is guided by two recirculating linear bearings riding on a common linear bearing rail. Each voice coil has a 1.5" [38.1 mm] stroke, generates 8.4 lbs [37.4 N] of continuous force and 25.2 lbs [112 N] of peak force.

The stage is supplied with two non-contact 1 micron resolution digital output linear encoders for position feedback.  Each head can be independently controlled using an H2W supplied two axis programmable motion control system.

Features:

  • Capable of independent or synchronized two axis control
  • High speed, high precision motion control
  • Horizontal orientation
  • Other stroke and force configurations available.

H2W Technologies is dedicated to the design and manufacture of linear and rotary motion products that are used in the motion control industry.  The complete line of linear electric motors includes: single and dual axis linear steppers, DC brush and brushless linear motors, voice coil actuators, and AC induction motors. Also offered is a complete line of ball screw, lead screw and belt driven positioning stages.

Other motion control products include: limited angle torque motors for compact, limited angular excursion rotary servo applications, 3 phase brushless rotary servo motors with matching digital servo amplifiers and permanent magnet linear brakes for fail-safe, zero power braking for baggage handling and people moving applications as well as amusement park rides.

With over 75 years combined experience in the linear and rotary motion field, the H2W Technologies team of engineers offers the optimal solution to the most demanding motion control requirements.
