Product Description:

The CTP32NLF28KAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series. As a member of the Cool Torque Performance series, it is intended to provide high incremental torque for industrial indexing devices, packaging actuators, and material-handling axes where repeatable open-loop motion is sufficient. The motor converts electrical pulses into fixed angular movement, supporting automation tasks that require precise positioning without complex feedback electronics. Its design emphasizes torque density while preserving standard NEMA mounting.

Its mechanical envelope follows the NEMA 34 outline with a frame width of Size 34 / 8.5 cm. Rated winding excitation is 2.8 A in bipolar operation, producing up to 7.8 N-m of pull-out torque in the CTP variant. The shaft can sustain axial forces up to 100 lbs (45 kg) in either direction and radial forces up to 65 lbs (29 kg) when measured at the shaft center. These limits help protect the bearings from premature wear during belt tensioning, coupling misalignment, and vertical load conditions. Two stacked rotor laminations shorten the magnetic path and help the motor achieve its torque rating while keeping detent torque low for smoother microstepping.

The windings are insulated for up to 340 VDC, enabling operation with higher-voltage step drives. Electrical access is provided through pigtail leads in a four-lead configuration, matching standard bipolar topology. A straight keyway shaft simplifies power transmission to pulleys or couplings, while NEMA through holes let the housing bolt directly to existing 34-frame brackets. The CT construction leaves no hardware at the rear of the case, providing clear access for encoder add-ons if required. The high-torque magnetic circuit is paired with the Cool Torque Performance thermal design to manage heat without external cooling.
