The FHA Series of dc brushless actuators provide a large hollow shaft up to 45 mm in diameter. This feature targets the actuators for use in robotics, machine tool, and other applications where cabling, laser light, or shafting need to be passed directly through the center of the actuator. Because zero-backlash, high-stiffness "S" Series harmonic drive gearing is used, these units deliver continuous rated torques of up to 1,730 inches-lb and positional accuracy better than 1 arc-min. Servo performance is achieved using hollow-shaft, rare-earth dc brushless motors with integral electronic commutation and high-resolution encoders for position and/or velocity feedback.

By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
