Design, engineering, and marketing students build the e-Bike of the future
Students from Cedarville University’s industrial and innovative design, mechanical engineering and business programs have created a sustainable e-Bike made with a wood frame. They are rolling out their creation now at North American Handmade Bicycle Show (NAHBS) — which runs March 10 to 12 in Salt Lake City, Utah. E-Bikes are a new trend among bicycle riders. An e-Bike comes equipped with […]
The Torque Equation and the Relationship with DC Motors
Understanding the torque equation and the relationship between speed and torque is an important part of selecting and operating a DC motor. DC motors are relatively simple machines: when the load on the motor is constant, speed is proportional to supply voltage. And when supply voltage is constant, speed is inversely proportional to the load […]
Bishop-Wisecarver Group Director of Marketing Wins Women in Manufacturing STEP Ahead Award
Bishop-Wisecarver Group (BWG), a WBENC-certified family of companies that offer guidance solutions, contract specialty manufacturing and mechatronic-based engineering services, today announced that Melsha Winchester, Director of Marketing, was selected as one of the Women in Manufacturing STEP (Science, Technology, Engineering and Production) Ahead Award winners for 2017. The STEP Ahead Awards, part of The Manufacturing […]
Motion applications for transducers and sensors
Transducers and sensors are essential components for data collection, systems monitoring, and control feedback. In motion-control applications, transducers take the form of rotary or linear encoders for position feedback, sensors such as tachometers for speed sensing, and even proximity switches to initiate or halt some machine action. In hydraulic motion control systems, for instance, pressure […]
New entry-level rotary module for semiconductor and electronics from ETEL
ETEL’s new DXR+ is the newest member of its direct drive rotary module portfolio. For years, ETEL has offered a DXR rotary table as an accessory to its motion stages and now, with important design changes, the DXR+ is available as a stand-alone entry level rotary module featuring a compact design, light mass, and large […]
FAQ: What is phase lag and what effect does it have on DC motors?
In a brushless DC (BLDC) motor, permanent magnets are mounted to the rotor, and the stator has windings that are energized by external current to produce electromagnetic poles. Brushless motors use electrical commutation to determine the switching sequence of the stator coils, and BLDC motors can be driven with either trapezoidal or sinusoidal commutation. Trapezoidal commutation is […]
Siemens introduces Sinamics V20 Smart Access web server module
Siemens’ Sinamics V20 Smart Access web server module is designed to mount directly onto the drive, transforming a mobile device or laptop into a virtual operator panel for drive control. By providing a wi-fi hot spot, the wireless connection on this module facilitates setup, programming, commissioning, production monitoring and maintenance on a variety of machines […]
FAQ: How do digital encoders simplify setup and zeroing?
In a recent Design World video, my esteemed colleague Miles Budimir and I got to assemble and zero an AMT31 commutation encoder from CUI Inc. As we’ve covered in other editorial, capacitive technology can outperform optical technology. Used for years in digital calipers and to measure rotational movement, capacitive technology in encoders replaces optical disks with a printed circuit-board rotor […]
