Product Description:

The CTM33NLF47KAA00 is a hybrid stepper motor manufactured by Kollmorgen within the CT Stepper Motors series. It belongs to the Cool Torque Maximum family and is used in automated machinery to translate discrete drive pulses into precise angular movement. This operating method supports repeatable incremental positioning in equipment that must stop at the same location over many cycles. It is commonly applied on conveyors, pick-and-place heads, and metering pumps where simple open-loop motion is acceptable.

This motor is configured with a frame size of Size 34 / 8.5 cm and uses a 3-stack lamination to increase magnetic flux density. At its nameplate current of 4.7 A per phase, the CTM winding produces up to 13.6 N-m of holding torque, supporting high-inertia loads during start-stop duty cycles. This combination helps the motor resist position shift while a load is held at standstill. The coils are insulated for up to 340 VDC, allowing connection to modern micro-stepping drives that use higher bus voltages for improved slew speed. A straight keyway shaft simplifies coupling to pulleys or gearheads, while bipolar windings minimize detent torque and permit four-quadrant operation when paired with a bipolar drive.

The motor is prepared for installation through NEMA through holes, and the shaft can tolerate an axial force of 100 lbs (45 kg) in either direction plus a radial load of 65 lbs (29 kg) at the center. These load limits allow direct belt tensioning or pinion mounting without external support bearings. Electrical termination is supplied as flying leads, and exactly four conductors exit the housing to accommodate bipolar drive topologies. Because no detachable connector is present at the rear, wiring remains direct and the back end is left open.
