Motion Control – Two Axis X-Theta Voice Coil Positioning System from H2W Technologies
Motion Control – Two Axis X-Theta Positioning System
Santa Clarita, CA —– Motion Control – H2W Technologies introduces a high acceleration, voice coil driven, XY-Theta positioning stage with a precision bearing system, which minimizes the amount of pitch, yaw, and roll in the system. The voice coil stage (VCS02-005-BS-01-MXYTh) is a closed loop positioning system that can be used for positioning applications that require a limited rotation theta stage integrated. The stage utilizes a custom low-profile design that utilizes a unique electromagnetic circuit design. The motor has a two-axis planar coil assembly that interacts with a common magnetic circuit. This circuit design allows for a minimal overall height of 2.93 inches [74.5 mm].
Each linear axis has a 0.23″ [6.0 mm] stroke; generate 0.50 lbs [2.2 N] of continuous force and 1.50 lbs [6.6 N] of peak force. The X and Y axes are guided by precision linear ball slide assemblies. It includes a one-micron resolution magnetic linear encoder on each linear axis. The theta axis has a rotary displacement of 10 degrees, a continuous torque of 2.2 in-lbs [0.25 Nm], and a peak torque of 6.5 in-lbs [0.73 Nm]. There is also encoder feedback on the theta axis that has 239000 counts per revolution. This design utilizes a moving coil in all three axes, which has a lower moving mass that enables the highest possible acceleration. Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.
Features:
- – Three-axis motion control
- – High acceleration
- – Compact footprint
- – Custom strokes and force configurations available
- – Cable carrier to route customer payload cables

Motion Control – Optimal Engineering Systems, Inc. (OES) Introduces New, Motorized, High Resolution Pan-Tilt Stages!
Motion Control – Pan-Tilt Stage

![]() |
Van Nuys, CA – — Motion Control – High Resolution, Motorized, Pan-Tilt Stages have been added to the extensive line of OES (Optimal Engineering Systems, Inc.) motion control products. These motorized Pan-Tilt Stages are available in two sizes. The PT60-1 Pan-Tilt Stage is a combination of two 60 mm (2.362 in.) rotary stages and the PT100-1 is a combination of two 100 mm (3.937 in.) rotary stages, set at a 90O angle to each other. The rotary stages of each Pan-Tilt stage features a high repeatability of 0.005O (18 arc-sec), a positional accuracy of 0.005O (18 arc-sec), and a resolution of 0.001O = 3.6” (10 Micro-steps per Step Motor Driver in use). These Pan (horizontal table)-Tilt (vertical table) Stages are deal for: Scanning, testing, inspection, assembly, positioning, laser and micro machining, pointing optics and cameras, and other applications.
The pan and tilt axes on both stages have precision V-grove and crossed roller travel guides and are driven by a worm gear with just of 0.005O (18 arc-sec) of backlash. These compact, easily integrated Pan-Tilt stages weigh just 2.0 kg (4.4 lbs) for the PT60-1 and 4.4 kg (9.75 lbs) for the PT100-1 and load capacities are 10 kg (22 lbs) and 20 kg (44 lbs) respectively).
Each axis is driven by a standard bi-directional stepper motor with a knob for manual adjustments and each rotary axis has a vernier scale for setup. The knob on each motor can be replaced with an optional encoder for position verification. Travel speed of each axis is 12O per second with a stepper motor or for higher speeds and closed loop operation, servo motors are available. Electrical connections are made using 9 pin DB-9 connectors.
The PT60-1 and the PT100-1 Pan-Tilt Stages can be ordered as complete plug-and-play systems with a multi-axis controller, joystick, trackball or keypad.
