Product Description:

The CTP10ELF16MAA00 is a two-phase stepper motor produced by Kollmorgen within the CT Stepper Motors series. It belongs to the Cool Torque Performance subgroup and is intended for positioning and indexing tasks in industrial automation where open-loop motion is acceptable. By converting discrete drive pulses into precise shaft rotation, the motor allows conveyors, small actuators, and labeling stations to move to commanded locations without feedback hardware.

This model uses four color-coded leads as its connection method, making connection straightforward for drives that supply a rated phase current of 1.6 A DC. The phase windings measure 2.15 Ω at 40 °C and exhibit an inductance of 3 mH, so current rises quickly while limiting switching losses. A bipolar drive can obtain the motor’s holding torque of 0.30 N·m, while the detent torque remains a modest 0.014 N·m for smooth microstepping. Electrical insulation is qualified for up to 80 VDC. Mechanically, the unit follows the NEMA size 17 envelope with a width of 42.7 mm, a body length of 34.3 mm, and an overall mass of 0.2 kg. English tapped holes on the faceplate support rigid mounting, and the short stack length helps maximize torque density within compact equipment.

The shaft can accept axial forces up to 6 lb push / 15 lb pull, and it can handle radial loading of 15 lb (6.8 kg) at the shaft center, so couplings and pulleys may be mounted without auxiliary bearings. A rotor inertia of 3.6 × 10⁻⁶ kg·m² helps the motor accelerate quickly between steps while damping overshoot. Each full step advances the output by 1.8°, coordinated with a metric shaft that is 5 mm in diameter and 20.07 mm long. The rear side of the housing carries no connectors or encoders, which streamlines installation in equipment that already encloses the drive electronics.
