Product Description

CT Series Step Motors are manufactured by Kollmorgen. The CTM31NLF99KAA00 is a step motor in the CT Series. Kollmorgen has designed the CT Series with distinctive features from all other step motors in the market. The CTM31NLF99KAA00 operates at cooler temperatures, produces higher torque, and supports higher shaft loads. CTM Series motors integrate patented enhancing magnets in the stator to offer an additional 25% torque at any speed. The improved power output originates from higher efficiency, which enables the use of smaller power supplies and drives. The CTM31NLF99KAA00 is integrated with distinctive features that offer various benefits.

The CT Series Step Motor is integrated with high torque magnetic designs that come with a small air gap, big rotor diameter, rotor magnets of high energy along with windings that are computer-controlled. This offers the highest torque in the smallest package.  Some of the benefits include lower energy use, reduced system cost, as well as faster, more compact machines. The CTM31NLF99KAA00 also features a cooling shell made of aluminum. The motor has aluminum ends to rapidly remove heat when mounted, which allows for higher torque ratings and current ratings

The CTM31NLF99KAA00 is integrated with high voltage insulation system encasing the stator. This eliminates gaps and joints that can fail, thereby increasing voltage ratings and reliability. CT Series Step Motors can be used not only with every standard drive, but also high performance, high voltage drives. The CTM31NLF99KAA00 also features a Large Bearing System for accommodating high side loading and high thrust loads. Step motors with a 23 & 34 NEMA size have the front bearing engaged with a snap ring. The rear bearing is attached in an O-ring to reduce motor noise and stop spinout.
