Most linear motion devices have a rotary equivalent, and voice coil actuators are no exception. While the versions depicted in most product images and videos are linear, rotary voice coil actuators fill a need for smooth, arc-shaped motion and torque production with fast response times. But unlike the design relationship between rotary and linear motors, […]

This allows for more applications that are using dc […]
Can piezo motors and electric motors be combined?
Piezo motors and electric motors are employed for very different uses. Piezo motors provide a high power-to-size ratio for very small movements – typically a few millimeters or less. They also have very fast response times and are self-locking, meaning they can hold a load in position during a power-off condition. Electric motors, on the […]
New Micro-Positioning Components and Solutions catalog from PI
PI (Physik Instrumente) has released a new catalog of engineered products necessary for precision positioning of medium loads used in industry and research. The products highlighted in the catalog are developed to move loads of 10 to 50 kg (22 to 110 lb) over distances up to 300 mm. Rotation stages provide rotation angles of […]
New angular positioning system for metrology and micromachining from HEIDENHAIN
The new SRP 5000 angular positioning system from HEIDENHAIN incorporates its high accuracy MRP 5000 angle encoder with accomplished bearing technology along with a unique ETEL torque motor with ultra-low detent torque. This combination allows for high stiffness with low cost of ownership and can easily replace rotary air bearing systems used for metrology. Industries […]
Case study: Motion-platform maker standardizes on I/O for measurement and control
Servos & Simulation Inc. is a manufacturer of motion platforms and control loaders. Recently the systems builder picked a Model 826 analog and digital I/O system on a PCI Express board from Oregon-based Sensoray for the primary measurement and control interface for their full product line. Servos and Simulation provides motion platforms and control loaders […]
Dual feedback voice coil actuator from H2W Technologies
The VCS20-020-CR-01-MC-F3K voice coil positioning stage has dual feedback capability.
