FAQ: How do I calculate the inertia of a servo-driven system?
Inertia, or more specifically, inertia ratio, is one of the most important factors in sizing a servo system. Inertia is defined an object’s resistance to change in velocity, and in servo-driven systems, it can be used as a measure of how well the motor is able to control the acceleration and deceleration of the load. […]
Formsprag Clutch introduces new clutches and brakes for aerospace applications
Formsprag Clutch recently launched a line of electromagnetic brakes that start, stop and hold loads in position with precise control for aerospace applications including flap actuators, drones, munitions, motor brakes, winch and tensioning systems, satellites, ball screw drives and robotic arms. The new line includes permanent and electromagnetic power-off friction and holding brakes. The new […]
The downside of patent protection
Leland Teschler – Executive Editor lteschler@wtwhmedia.com On Twitter @DW_LeeTeschler MUCH angst has been expressed over patent trolls that buy up low-quality patents then sue the bejesus out of potential infringers to “enforce” IP rights. Lest you think patent suits by these guys are over money earned from patents, consider this: Scholars at the National Bureau […]

Design World Future of Engineering editorial: Driverless cars a done deal
This piece is part of Design World’s 10th Anniversary special for October 2016, where we take a look at how far design engineering has come in the last decade … and how far it will go by 2026. If you’re leery about riding in a car sans steering wheel, you’ve got company. But everyone from Google and […]
FAQ: When to use a DC drive vs an AC flux-vector drive
DC drives are known for their ability to provide tight speed control and full torque at any speed, whereas traditional AC drives had a more narrow speed range and limited torque control. But newer AC drives using vector control, also known as field oriented control (FOC), have performance similar to DC motor and drive systems. Through […]
Enjoyable Miles for Manufacturing run with industry colleagues to support STEM education
Last week at IMTS 2016, Tim Pirie of CGI Inc. — a manufacturer that designs and builds precision servo gearboxes for ac, dc, step, and servomotors — told me about the Miles for Manufacturing 5K event — and it was the first I’d heard of it. Miles for Manufacturing is a traveling event that’s been held at […]
Applied Motion Products adds NEMA 34 size to StepSERVO Integrated Motors lineup
Applied Motion Products now offers NEMA 34 frame StepSERVO Integrated Motors. The addition of these larger frame sizes in the successful StepSERVO product offering represents a widening of the product range, which already included smaller frame sizes NEMA 11, 17, 23 and 24. With the larger NEMA 34 frame size, StepSERVO Integrated Motors can now […]
