Product Description:

The CTM33NLS59KAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series. It belongs to the Cool Torque Maximum series, which focuses on high torque and efficient operation. The motor uses a size 34 frame measuring 8.5 cm and is installed on positioning axes that convert digital step commands into precise rotary motion for conveyors, pick-and-place heads, and indexing tables in industrial automation. Its hybrid construction supports repeatable step positioning in applications that rely on accurate incremental motion.

The motor delivers a holding torque of 1500 oz-in, and its bipolar winding can reach 13.6 N·m when configured as a CTM unit to move high-inertia loads. Each revolution is divided into 200 full steps by a 1.8° step angle, with accuracy held to ±3%. A three-stack lamination increases magnetic length, while the straight keyway shaft transmits torque without slip. Per-phase input is rated at 5.9 A DC, with a resistance of 0.70 Ω and an inductance of 2.6 mH. Six lead wires provide the connection style, rear accessories are omitted, and NEMA through-hole mounts secure the housing. The allowable axial load is 100 lbs, which helps protect the bearings during thrust coupling or belt tensioning. The six-lead arrangement also supports common stepper drive wiring methods used to balance speed and torque behavior.

Detent torque is 52 oz-in, which allows low-cogging manual shaft positioning when the motor is de-energized. Side loading is accommodated by a radial limit of 65 lbs at the shaft center, which supports belt and coupling loads when shaft forces remain within the stated limit. The coils operate at a nominal phase voltage of 4.1 VDC and dissipate heat through a 1.36 °C/W thermal path aided by the motor’s 9.3 lb mass. Electrical insulation measures 100 MΩ and is surge tested to 340 VDC, while rotor inertia of 0.0555 oz-in-s² supports quick acceleration. Six leads simplify wiring for standard stepper drive connections.
