Protecting AC Motors From Destructive Shaft Currents

The use of variable-frequency drives (VFDs) to control AC motors has increased dramatically in recent years. In addition to low operating cost and high performance, they save energy. Today, the challenge facing system designers and engineers is to minimize damage to AC motors from shaft current.

Getting on the Right Motion Bus

As modern machines have become more advanced, the complexity involved in motion control has escalated. Today, servos have replaced cams and gears on machines and multiple axis of synchronized motion control have become commonplace. Distributed motion control requires busses able to handle rigid jitter and timing demands including:

Integrated Motor Control Meets Aviation Needs

The trend in aircraft design is toward more efficient brushless DC motors. A integrated motor drive module for brushless DC motors from International Rectifier (El Segundo, CA) reduces the effort of programming the motor control and simplifies certification. Because the device is configured for sensorless field oriented control, the elimination of Hall sensors improves reliability while reducing component count. It enables the aircraft to achieve greater fuel economy and lower maintenance costs.

Motion Control Market Marches Toward Higher Integration and Performance

Evolutionary rather than revolutionary changes characterize the motion control market. Motors and motor controllers continue to gravitate toward higher performance and functionality as market demands become more stringent. At the same time, higher levels of intelligence — driven largely by software advancements, are giving engineers greater control and flexibility in designing motor-based systems.

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.

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.

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.
