Motion Control

Using Motion Control to Guide Augmented Reality Manufacturing Systems

Assembly is a complicated, sometimes tedious process that often unfolds sequentially along a series of stations. In the manufacture of complex equipment such as jet engines and automobiles, technicians are guided through their work by referring to printed manuals, which document the various steps required. These processes usually demand the use of hand tools with little in the way of automation available either at the tool or verification level — in fact, all actions typically are performed manually. As a result, quality and performance times are dependent upon each technician’s technique and preferences, leaving room for individual differences and, at times, errors.

Brake System Development Accelerated With 3D Modeling

Tractair Ltd., based in Brough, UK, designs, manufactures and installs air and hydraulic brake systems for special applications. The company works closely with the design engineers of major international tractor manufacturers and other OEMs to ensure that the braking systems are fully integrated. The company has been closely involved in the development of air brakes for agricultural and other off-road vehicles since 1985 and continues to adapt available technologies to meet the demands of increasing loads and speeds handled by agricultural and construction vehicles, both on and off the highway.

Motor System Enables Elevators to Ride Smoothly

Many factors have contributed to the fact that in the past five years, home elevator sales have doubled. These include the aging of the affluent baby-boom generation. In the next five years, an estimated 70 million people will be of retirement age; many of them will be looking at retaining their independence by staying in their own homes and adding features such as elevators to make living more accessible, or moving to customized homes that already include such advantages. According to a Florida State University study, a home elevator can add 10% to the selling price of a home.

Encoders for Linear Motors in the Electronics Industry

The semiconductor industry and automation technology increasingly require more precise and faster machines in order to satisfy growing demands on miniaturization, quality, and manufacturing cost reduction. Linear motors gradually are becoming more important in such highly dynamic applications with one or more feed axes. The benefits of this direct drive technology are low wear, low maintenance, and higher productivity.

Magnetostrictive Sensor System Helps High-Performance Car Brake Quickly

The Bugatti Veyron is the world’s fastest street-legal motor vehicle, a high-end passenger car that can reach speeds of more than 200 miles per hour. These high speeds require extra braking power, which comes from raising an aerodynamic rear wing and generating additional braking forces. The Veyron can decelerate from 230 mph to 0 in only 7.5 seconds, largely due to the extra down force achieved with the rear wing, which is raised within 0.4 seconds to a 55° angle.

Creating Motion Control and Drive Electronics With an FPGA-based System

Complex machines in semiconductor manufacturing often have tough performance requirements for motion control. When traditional PLCor PC-based motion controllers fail to meet these requirements, machine builders turn to custom board development — a time-consuming and expensive process. Recent advances in embedded technologies have made it possible to use FPGA-based COTS platforms to not only meet those requirements, but also to get to market faster by using graphical system design.

Electric Motors vs. Fluid Power: Robotic System Designers Have a Choice

Robotic system designers should choose the right power source for the job. Often, electric motors are chosen without thinking about the benefits of hydraulics or pneumatics. For applications where precise control of large forces and smooth motion are required, or applications that require “forgiveness” in the motion, fluid power can deliver significant benefits compared to electromechanical motion.
