Product Description:

The CTP12ELF16MAA00 is a hybrid stepper motor offered by Kollmorgen within the CT Stepper Motors series. Classified in the Cool Torque Performance Series, the unit is intended for indexers, small gantries, or metering pumps where discrete angular positioning is needed. By converting drive pulses into incremental motion, the motor supplies open-loop rotary actuation for mechanical stages and other motion axes. Its compact format also suits equipment layouts where installation space is limited but repeatable step-based movement is still required.

Electrically, the two-stack Size 17 frame produces a holding torque of 0.56 N-m while drawing 1.6 A DC per phase at a rated winding voltage of 4.3 VDC. The phase resistance of 2.65 Ω and inductance of 4.9 mH affect current rise during commutation and influence how the motor responds to drive pulses. Insulation resistance is 100 MΩ, and the winding withstands up to 80 VDC for use with low-voltage micro-stepping drives. Four color-coded leads connect the two motor phases, and English-tapped mounting holes allow the housing to be secured to a panel or gearbox. The Cool Torque Performance design emphasizes high torque density from a compact stack length, which helps the motor fit into space-conscious motion systems.

Mechanically, the motor accepts axial forces of 6 lbs in push and 15 lbs in pull, and it withstands a radial load of 15 lbs at the shaft center. The metric output shaft is 5.000 mm in diameter, and the rotor inertia is 0.00106 oz-in-s², which supports quick acceleration in short point-to-point moves. Each pulse advances the rotor by 1.8°, so 200 full steps complete one revolution without feedback devices. Overall mass is only 0.34 kg, which helps limit moving load on small gantry axes and similar mechanisms. Thermal resistance is 4.71 °C/W, allowing the windings to stabilize below insulation limits when rated current is applied. Because the motor has no rear configuration, cable routing remains uncomplicated, and the four-lead connection pairs easily with standard bipolar stepper drives.
