Vene, vede, da Vinci the prologue
Albert Einstein often said that imagination is more important than knowledge. Not surprisingly, he possessed both in abundance. So, too, did Leonardo...
In Response
A great man I am particularly fond of your recent regular feature about Nikola Tesla (whom I while in college and who impressed me to no end). I read...
A disconnect at the paper mill
As one of Alabama's largest paper recyclers, Weyerhauser Co. recognizes the need to minimize energy costs at its Pine Hill paper mill. The company burns...
Stepmotors now close the loop
Stepmotor drive systems are known for their inherent open-loop control simplicity. But compared to servo systems, they perform poorly in applications...
Getting out of a sticky situation
Researchers at the National Institute of Standards and Technology (NIST) and George Mason University (GMU) have found an easy way to bond thermoplastic...
Acquisition increases semiconductor and medical motion control services

Putting the squeeze on
They're one of the simplest components in power transmission. They're also one of the most indispensable. Among their many roles, shaft collars hold sprockets...
Tuning servomotors
There are two types of motion control engineers: Those who are comfortable tuning a servo loop, and those who aren't. The latter basically, have two options....
Raising the bar
Even if you could mathematically model systems exactly, the physical world is too messy has too many variables to flawlessly produce paths described by...
Linear friction brakes
Linear brakes are mechanical devices on linear motion systems that hold loads stationary or are used as failsafe devices. Typically, an actuator (a linear...
