Allen-Bradley High-Power Kinetix (HPK-Series) motors are designed to deliver servo motor precision and performance at the power ranges and prices of induction motor technology. “We’ve never offered a servo motor solution with power ranges over 30 horsepower, but the HPK motor extends the normal power range of a traditional servo motor solution up to 150 horsepower,” says David Hansen, product manager at the vendor.
“This allows machine builders to increase acceleration and improve the positioning, precision and overall system throughput, in some cases as much as 25 percent.” The electrical winding design of the HPK-Series motor has been optimized to mimic the speed/torque curve of a conventional permanent magnet servo motor, allowing the HPK motors to deliver peak torque that is twice the continuous torque when running at base speeds. The motors also are equipped with single- or multi-turn, high resolution absolute feedback that eliminates the need for time-consuming homing routines, improves velocity regulation, and expands the system’s inertia matching capacity.
