Product Description:

The CTP12ELF07MAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series. It is part of the Cool Torque Performance line and offers high-torque performance in a two-stack, size-17 package for indexing tables and light pick-and-place axes. The motor converts incremental drive pulses into precise mechanical motion, uses a 5 mm metric shaft, and mounts with English-tapped holes so it can fit compact automation assemblies without requiring a large installation envelope. Because it is a hybrid stepper design, it combines toothed rotor geometry with controlled phase energizing to produce predictable incremental movement.

This model draws 0.65 A DC per phase through four leads and has a phase resistance of 15.7 ohms, which influences the drive voltage needed for rated output. Its phase inductance of 30 mH slows current rise in a controlled way, helping microstepping drives shape torque more smoothly during low-speed motion. In bipolar operation, the motor provides 0.56 N-m of holding torque, and its 1.8° step angle gives the controller a standard full-step increment for open-loop positioning. An 80 VDC insulation rating separates the windings from the laminated core, while detent torque of 0.021 N-m helps keep the shaft from drifting after power is removed. The motor mass is 0.34 kg, and the rotor inertia is 0.0000075 kg·m².

The laminated stack measures 48.3 mm in length and 42.7 mm in width, which helps the motor fit into tight machine spaces. The shaft can tolerate an axial load of 6 lbs and a radial load of 15 lbs at the shaft center, giving it the capacity needed for light couplings, pulleys, and similar transmission elements. The motor provides 200 full steps per revolution, and no rear add-ons are supplied, so the back of the housing remains unobstructed for airflow and clearance. This open rear area also helps when the motor is installed near brackets or panel surfaces during installation.
