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?
