"Well begun is half done," a quote that most reference materials attribute to Aristotle, certainly applies when selecting mechanical power transmission products. A selection process that is well thought out at the start can ensure that the product selected will be properly sized and appropriate to the application at hand.
In this paper, Edward Hage, founder of specAmotor.com, an online motor calculation and selection tool, focuses on the overheating of electric motors. Presented here is a calculation method with which the temperature and heat development of a direct current (DC) motor and a brushless motor can be predicted accurately.
The ball screw drive is an assembly that converts rotary motion to linear motion and vice versa. The ball screw drive consists of a ball screw and a ball nut with recirculating ball bearings...
One of the fun parts of the motion industry is involvement in popular movies! Motor specifications can be a bit rough: "I need to spin a 120-pound actor (and chair) 180 degrees in one-half second. He will be sitting up-right."
How to select a guide wheel with the properties best-suited for a given application to create a system that reduces design costs and engineering changes, and lowers warranty, assembly, installation and mounting costs.
Key technical drivers which can be addressed by advanced PM manufacturing technologies are, for example, the need for system downsizing in transmissions and differentials, the need for developing systems with higher power density and the strong NVH (Noise Vibration Harshness) requirements - especially for electrified transmissions or e-axle solutions.
After a brief introduction to the importance of gear pumps in internal combustion engines, as well as in the most diverse hydraulic applications, a calculation method was applied that allows for sizing with considerably higher delivery rates. Upon identifying and analyzing a traditional pump, along with two construction solutions of asymmetric gear pumps, we then compared their related performances.
A reader asks for clarification on last issue's Ask the Expert column about ball screw sizing.
The world of high horsepower drives often calls for mechanical design to be approached from different perspectives. As motors, gearboxes and machines increase in size, power density can become disproportionate from one driveline component to the next, emphasizing the need for more rugged, robust and compact equipment.
