Product Description

The CTM31NLF45KAA00 is a stepper motor designed and manufactured by Kollmorgen. The motor’s holding torque is rated at 6.7 N-m and its inductance stands at 9.1 milliHenrys. It has a current rating of 4.5 Amperes per phase, weighs 1.9 kilograms, and measures 64 millimeters in length. The CTM31NLF45KAA00 has a NEMA 34 frame size and belongs to the CTM (Cool Torque Maximum) series. Motors in this series have high voltage insulation for faster design cycles and high reliability, large bearings for a longer life and for use with leadscrew applications.

The Kollmorgen CTM31NLF45KAA00 motor, as with other motors in the same series, is generally smaller in size thereby saving on space and lowering system costs without interfering with its performance and efficiency. When making connections to the motor, a lead connection style should be maintained with the motor supporting four connections. The motor’s winding current stands at 4.5 Amperes and its front shaft has a straight keyway. For the insulation, the motor belongs to the Class B insulation class that has a maximum temperature rating of 130 degrees Celsius, an insulation voltage rating of 340 Volts DC and an insulation resistance of 100 mega Ohms.

The CTM31NLF45KAA00 has a radial shaft load rating of 29 kilograms measured at a speed of 1500 revolutions per minute for 20000 hours. When in operation, the motor supports a maximum ambient temperature of +40 degrees Celsius and a minimum of -20 degrees Celsius. The motor has a step angle of 1.8 degrees, step accuracy of +-3 percent, and 200 full steps per revolution. Note that all Kollmorgen stepper motors in the CTM series employ an innovative cooling technology.
