Product Description:

The CTP33NLF29KAA00 stepper motor is produced by Kollmorgen within the CT Stepper Motors series and belongs to the Cool Torque Performance Series, a high-torque subset for consistent positioning in industrial equipment. Designed for open-loop motion, the unit converts drive pulses into fixed angular increments without feedback devices. This operating method suits indexing tables, pick-and-place modules, and metering pumps where repeatable starts, accurate dwell periods, and strong holding force are required. It is also a practical fit for machines that use pulse-count positioning and need stable low-speed movement without a separate encoder package.

The motor can handle an axial shaft load of 100 lbs (45 kg) in either direction and a radial load of 65 lbs (29 kg) measured at the shaft center, which supports belt-driven or overhung loads within normal machine layouts. Its CTP-rated holding torque of 11 N·m helps the rotor resist motion at standstill and support acceleration during start-stop duty. Each phase draws 2.9 A, a current level suited to common microstep drives used in industrial stepper systems. The 8.5 cm frame matches the Size 34 envelope, and the straight keyway shaft provides secure torque transfer to pulleys, couplings, or similar drive elements. Power exits through flexible leads, which helps when cable routing space is limited behind the motor. The rear face carries no auxiliary hardware, so the back end remains unobstructed for compact installations.

The insulation system is rated for 340 VDC, allowing the motor to operate with higher DC bus voltages while maintaining appropriate electrical isolation. Installation uses NEMA Through Holes, so the frame bolts directly to standard mounting plates without a special adapter pattern. The magnetic circuit uses a 3 Stack lamination, which increases torque output without requiring a larger frame size. The winding is Bipolar, using two identical phase coils for full-bridge stepper drives and steady current control. This winding arrangement supports smooth low-speed operation and makes the motor compatible with standard two-phase drive topologies used in automated machinery.
