Product Description:

The CTP33NLF13KAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series. As a member of the Cool Torque Performance Series, it delivers higher stall output in a compact frame. The unit converts phase sequences from a two-phase bipolar drive into precise incremental rotation suitable for indexing tables, packaging axes, and metering pumps. A three-stack magnetic core raises detent and pull-out limits, enabling open-loop positioning without additional feedback devices.

A mechanical highlight is its ability to withstand an axial end thrust of 100 lbs (45 kg) in either direction, protecting thrust-loaded couplings and lead-screw mounts. When energized in bipolar mode, the CTP variant develops a holding torque of 11 N-m, allowing direct coupling to medium inertia loads without gear reduction. The motor occupies a Size 34 (8.5 cm) frame, so it shares bolt patterns with standard NEMA 34 gearboxes and brackets. A laminated three-stack stator lets this torque be produced with only 1.3 A of phase current, reducing drive heat dissipation requirements. Electrical insulation is qualified for 340 VDC, providing ample margin when the motor is driven by higher-voltage micro-stepping amplifiers that use DC bus links above nominal phase voltage.

The radial bearing system supports 65 lbs (29 kg) at the shaft center, so the motor can carry side-mounted pulleys while still honoring the axial rating cited above. Mounting is simplified by NEMA through-holes that let the housing bolt directly to plates or machine frames without adapter rings. Power conductors exit as four lead connections, matching full-coil bipolar wiring schemes and permitting quick series or parallel configuration inside the cabinet. A straight keyway shaft profile transmits torque into couplings without relying on compression-type hubs, which further protects the bearings from excessive clamp loads.
