Product Description:

The CTP20NLS13NAA00 is a hybrid stepper motor manufactured by Kollmorgen and listed in the CT Stepper Motors series, which is also referred to as the Cool Torque Performance Series. Built around a Size 23 (5.7 cm) frame and a short stack lamination, it converts pulse commands into 1.8° mechanical steps for indexed motion in automated equipment. This round-body motor with a smooth shaft provides open-loop positioning without an integral feedback device, making it suitable for pick-and-place heads, light conveyors, and small screw drives used across factory automation.

At a winding current of 1.3 A DC, the motor produces a holding torque of 0.71 N·m. Six leads permit series or parallel hookup, and the phase circuit has a resistance of 4.39 Ω and an inductance of 5.2 mH, which influence current rise and motion smoothness during stepping. The insulation system withstands 340 VDC, allowing use with high-bus-voltage microstepping drives. Rotor inertia is kept low to support quick reversals, while the thermal resistance helps describe how winding heat moves through the motor during continuous duty. The NEMA through-hole mount simplifies attachment, and the motor is supplied without rear-mounted hardware so an external encoder can be added when the application requires one.

Mechanically, the shaft is ground to 6.35 mm Dia × 20.57 mm L, which supports direct coupling to pulleys or shaft couplers. Total mass is limited to 0.45 kg, helping reduce moving load on high-speed axes and compact positioning stages. Axial loading is rated at 50 lbs (23 kg) in either direction, and radial loading reaches 20 lbs (9 kg) at the shaft center, which supports moderate belt tension and lead-screw side loads. The motor uses six electrical leads, and the rear configuration is not equipped with additional hardware. Its short stack layout remains consistent with the series design approach for elevated torque density at the standard step angle.
