Product Description:

The CTP33NLF75KAA00 stepper motor is produced by Kollmorgen as part of the CT Stepper Motors series. It belongs to the Cool Torque Performance family within that line and is built for open-loop positioning tasks in industrial automation such as indexing tables, material feeders, and small gantries. By energizing its stator phases in sequence, the unit converts electronic pulse commands from a micro-stepping drive into incremental rotary motion with fixed step angles, allowing repeatable positioning without an external encoder.

A phase current of 7.5 Amps is the maximum continuous coil excitation for this motor, while the bipolar winding provides a holding torque of 11 N-m in the CTP variant. The straight shaft can handle an axial load of 100 lbs in either thrust direction, and the front face follows NEMA size 34 dimensions with an 85 mm frame identified as Size 34. Internal insulation is rated for 340 VDC, which sets the coil-to-frame dielectric limit for drives that use high bus voltages during micro-stepping. Four discrete leads exit the housing, matching bipolar drive topologies that require separate phase terminations.

The shaft can also withstand a radial load of 65 lbs at its centerline without exceeding bearing life targets, so belt tension and pulley overhang must remain within that limit. The motor uses NEMA through holes for installation, allowing direct mounting to standardized plates without additional adapters. Power is transmitted through a straight keyway shaft interface that helps lock the hub against stepwise torque, and the magnetic stack uses a 3 Stack configuration for increased rotor length and higher mid-range torque. The rear configuration is open, so optional encoders or fans can be added without disturbing the factory front seals. This layout supports flexible integration on equipment that needs added feedback or supplemental airflow.
