To encourage more builder, integrator and user participation in our Real Answers section, we'll award a $100 gift card every quarter to the best, most experience-based builder, integrator or user answer, as chosen by the Control Design editors, that we print and post during each three-month period. Vendors aren't eligible, and all entries must be posted in the Comments section here and emailed to RealAnswers@putman.net. This quarter’s award will be made in June.
Here’s our first question from a machine builder.
We upgraded to high-efficiency single-speed ac motors on our metal-cutting machines about five years ago. We are wondering if now is a good time to revisit the motor market and seek improved solutions. What significant improvements, if any, have occurred in the past five years with respect to single-speed ac motors in the 1-25 hp range?
