Kollmorgen is internationally recognized for their high-quality CT series step motors, some of which feature patented enhancing magnets in their stators, allowing 25% more torque across all speeds. The CT series utilizes high torque magnetic designs integrated with a computer-controlled windings, large rotor diameter, and smaller air gap, creating maximum torque in a compact package. The motors are encased in aluminum cooling shells for rapid heat extraction, allowing for higher current and torque ratings, particularly when mounted. They operate at peak torque for extended periods at low temperatures. The motors also include large bearings to accommodate high side and thrust loads. Some models feature snap ring-retained front bearings and O-ring-mounted rear bearings to minimize noise and prevent spin-out. For instance, the RoHS-compliant model, CTP20NLF27NAA00, has a 5.7 cm frame size, NEMA through-hole mounts, a round, smooth front shaft, and a winding current of 2.7 Amps.
