Bosch Bosch Rexroth will showcase an Open Mechatronics demonstration at this year’s ATX West trade show. The demonstration utilizes Rexroth’s Open Core Engineering solution on an L25 controller in conjunction with an Excel spreadsheet to program the motion. The motion design demonstrates the position of a two-axis Cartesian system with a CKR X axis, an […]
Applications
Servo motor or stepper motor? How to choose
The overwhelming majority of linear motion applications (with the exception of pneumatically-driven types) use either a stepper motor or a servo motor to provide torque to the driving mechanism, which is typically a ball or lead screw, rack and pinion, or belt and pulley system. And unlike other components involved in linear motion, when choosing a motor, […]
Leadscrews: Motion system mainstays
Among the methods available for converting rotary motion to linear, leadscrews are a mainstay. A leadscrew, or power screw, is a threaded rod or bar that translates rotational motion into linear motion. Leadscrews generate sliding rather than rolling friction between a nut and the screw. Consequently, higher friction means a lower overall efficiency. And efficiency, […]
Precision motion and positioning systems to showcase at Photonics West 2017
Descend the escalator and enter the exhibit hall to the world’s largest multidisciplinary photonics event, taking just a few steps past the entrance, PI’s booth displays the latest state-of-the-art precision motion technologies. PI engineers are on-hand to answer questions and help you find the right solution for your precision motion project in industry, research, or […]
Where linear motors improve designs: Application example in multi-axis stage
Machine-tool applications and the manufacture and assembly of semiconductor components account for more than half of all linear-motor use. That’s because linear motors are precise (albeit costly compared to other linear-motion options). Other applications for these relatively new motion components also include those that need fast and precise positioning or slow and extremely steady strokes. […]
Linear actuators: belt driven vs. rack and pinion driven
Belts and rack and pinions have several common benefits for linear motion applications. They’re both well-established drive mechanisms in linear actuators, providing high-speed travel over extremely long lengths. And both are frequently used in large gantry systems for material handling, machining, welding and assembly, especially in the automotive, machine tool, and packaging industries. Timing belts for linear […]
How to estimate your linear actuator needs with minimal application data
Choosing linear motion components during the development phase of a project has been a source of frustration for designers and application engineers for decades—especially when it comes to complex subassemblies such as linear actuators. Consider for a moment the influence that a linear actuator has on the overall machine design. First of all, in an actuator, […]
Motion applications: Electric actuators in new designs
Electric actuators come in versions as small as syringes for medical applications to those big enough to drive industrial presses. These muscles of precision motion usually incorporate an electric motor and rotary-to-linear device for conversion of torque to linear force. No matter the application, electric actuators deliver repeatability that’s indispensable for moving loads to a […]
