Product Description:

The CTP12ELS05MAA00 is produced by Kollmorgen within the CT Stepper Motors series and uses the Cool Torque Performance designation for high torque output in a compact frame. This unit converts digital pulse trains from an indexer or PLC into precise incremental rotation, allowing position control in pick-and-place stations, small conveyors, and metering pumps where open-loop operation is suitable. Its compact format also makes it practical for motion axes that need straightforward positioning without a more complex servo system.

When driven in bipolar mode, the motor develops 0.56 N-m of holding torque with a phase current of 0.5 A, which helps reduce drive heat and power-supply demand. Motion resolution is 200 full steps/rev, and the two-phase winding uses a 2-stack lamination for consistent incremental movement. Six insulated leads allow series or parallel wiring, and the motor uses flying leads rather than a connector, so the cable can be spliced if needed. The windings have an insulation resistance of 100 Megohms and an insulation voltage rating of 80 VDC. The mounting holes are inch-tapped to match NEMA hardware, and the design focuses on strong low-speed torque without external gearing.

The motor uses a Size 17 (4.2 cm) square frame and has a housing length of 48.3 mm, which helps it fit tightly packed axes. Its body width is 42.7 mm, and the hardened shaft can support up to 15 lbs radial load at the center. It can also accept 6 lbs of push or 15 lbs of pull axially without additional bearings. The output shaft is 5 mm in diameter and 20.07 mm long for direct coupling to precision pulleys. Each command advances the rotor by 1.8°, and step positioning error remains within ±5%. No rear accessories are installed, which keeps the overall depth short and simplifies cable routing.
