Product Description:
The CTM22NLS31NAA00 is a hybrid stepper motor manufactured by Kollmorgen as part of the CT Stepper Motors series. It belongs to the Cool Torque Maximum line and carries the Enhanced Series maximum torque and efficiency designation, indicating an electromagnetic design focused on high output for its frame size. This model is intended for indexing tables, pick-and-place axes, and other automation duties that require repeatable open-loop motion without encoder feedback. By converting pulse commands from a microstep drive into discrete angular movement, the motor supports accurate positioning while keeping the drive system mechanically simple.
Mechanically, the unit uses a standard Size 23 frame and has a body length of 84.3 mm. Its two-stack lamination supports a bipolar holding torque of 3.32 N·m, which helps the motor resist load movement at standstill without increasing the external frame size. Motion resolution comes from a 1.8° step angle, giving 200 full steps per revolution within a linear accuracy band of ±3%. The two phases are brought out through six lead wires, and the winding has a phase inductance of 2.1 mH. A thermal path of 2.62 °C/W and insulation resistance of 100 MΩ support stable operation when adequate airflow is available.
The electrical profile includes a phase current of 3.1 A DC and an insulation withstand rating of 340 VDC. Rotor inertia is 0.0068 oz-in-s², which helps the motor respond quickly during starts and stops in short-cycle positioning tasks. The round smooth shaft can accept a 50 lb axial load in either direction and a 20 lb radial load at the center, while the NEMA through-hole mount secures the housing directly to the machine. The motor has no rear shaft configuration, and the total shipping mass is 1.13 kg. The plain shaft layout is suitable for couplings, pulleys, and other compact power transmission elements selected for the axis.
