Product Description:

The CTP33NLF99KAA00 is a stepper motor produced by Kollmorgen as part of the CT Stepper Motors series. Belonging to the Cool Torque Performance Series, this three-stack device supplies high holding torque for indexing tables, labelers, or pick-and-place axes where simple open-loop control is preferred over servo feedback. By advancing the rotor in exact electrical steps, it delivers repeatable positioning and low-speed motion control in automated equipment. This operating method suits machines that need accurate incremental movement without a separate feedback device.

The motor can be installed and driven within several mechanical and electrical limits. The housing matches a Size 34 / 8.5 cm frame, allowing direct replacement of other NEMA 34 devices without bracket changes. Each phase can be energized up to 9.9 A, and under bipolar excitation the CTP variant develops 11 N-m of continuous torque for high-inertia loads at low speed. An axial thrust capability of 100 lbs in either direction helps protect the bearings during belt tensioning, while the insulation system is rated for 340 VDC, permitting connection to high-bus microstepping drives. The motor uses flying leads for electrical connection, and the body carries three laminated stacks to increase magnetic flux.

Side loading and mounting details support diverse mechanical couplings. A radial load of 65 lbs, measured at the shaft center, helps limit premature bearing wear when pulleys are mounted. The motor uses four external leads, simplifying hookup to full-step or half-step drives. The front face employs NEMA through holes so the motor can bolt directly to gearboxes or end plates, and torque is transmitted through a straight keyway shaft. There is no rear accessory, so axial space is minimized. This layout is useful when the motor is mounted close to panels, couplings, or guards that leave little clearance behind the housing.
