Empire Magnetics offers hollow-shafted motors for industrial processes, such as manufacturing fiber optic cable and designing radar antennas, robots, and high-speed laser scanner systems. Direct-drive hollow-shaft motors increase speed and acceleration, while providing better accuracy and faster response times when compared to motor driven mechanical arrangements. Mechanical drive arrangements add inertia to a system, resulting […]
Rotary encoders from HEIDENHAIN meet new standards for explosive environments
HEIDENHAIN’s ATEX series of encoders for potentially explosive atmospheres meet the new standards required today for motion control applications. These HEIDENHAIN ExN and ROx 400 rotary encoders feature a sturdy design with increased wall thickness, smaller cable diameter, and variations for multiple zones and atmosphere classifications. Many industries, such as oil and gas, printing, and […]
New 2-phase stepper motors with electromagnetic brakes from Oriental Motor
Oriental Motor’s new 1.8° and 0.9° PKP Series 2-phase stepper motors are available with built-in power-off activated preassembled electromagnetic brakes. When power is accidentally cut off due to unexpected events, such as a blackout, the electromagnetic brake holds the load in position to prevent it from moving. When the motor is at standstill, it can be […]
Of philosophers and welders; not an either/or proposition
The Internet has been in a tizzy over the comments made by Florida Senator Marco Rubio during a recent Republican presidential debate. During the debate, Rubio stated that “Welders make more money than philosophers” and also that “We need more welders and less philosophers.” Ordinarily I wouldn’t wade into such dustups during a political campaign […]
Moticont hollow-core voice-coil motors feature low inertia, high precision
Low-inertia hollow-core voice-coil or moving-coil linear motors from Moticont feature high acceleration, precise positioning to less than one micron (0.00004 in.), high reliability, and low cost. The cleanroom friendly, non-commutated motors are available in 23 off-the-shelf standard sizes with open apertures of 0.125 in. (3.2 mm) to 2.000 in. (50.8 mm). The linear motor’s hollow […]
48 mm hollow-shaft brushless motors
Koford Engineering’s new line of 12 to 24 V, 48 mm diameter slotless brushless hall sensor motors feature a 10 mm hole through the center of the motor shaft. The motor features a free running temperature rise as low as 3°C which can be helpful for optical and scientific instrument applications. Ceramic hybrid bearings are […]
ACS intros new compact EtherCAT drive modules
ACS Motion Control has launched a new series of compact EtherCAT drive modules for servo, step, and voice coil motors.

NORD offers premium efficient alternative to industry-standard worm units
NORD Drivesystems’ new SK92.1 and SK93.1 series helical-bevels boast gear efficiencies of up to 97%. Typical right angle worm reducers range in efficiency from 40 to 90% depending on size, ratio and output speed. The increased efficiency of NORD’s two-stage bevels can result in as much as 30% energy savings. NORD makes it easy to […]
New innovation center at Case encourages out-of-the-box thinking
The contemporary maker movement has done much to raise awareness of engineering and design among the general public. By shining a spotlight on the process of innovation, it has sparked a renewed interest in manufacturing as well as careers in engineering and design. Recently, some colleagues and I were given a tour of a brand […]
