Product Description:

The CTM32NLF28KAA00 is a hybrid stepper motor produced by Kollmorgen for the CT Stepper Motors series and the Cool Torque Maximum line. As a two-stack, size-34 motor, it supports open-loop position control in indexing tables, packaging axes, and light gantry stages where repeatable motion is needed without encoder feedback. Its mechanical interface follows NEMA mounting practice, so it fits standardized machine frames and brackets commonly used in industrial automation. This layout makes the motor easy to integrate into equipment that uses common stepper motor mounting patterns.

The motor’s shaft can withstand an axial load of 100 lbs in either direction, which supports thrust from lead screws and similar drive elements. Rated bipolar holding torque for the CTM option is 9.5 N-m, providing strong static resistance to load movement when the motor is energized at standstill. Electrical termination uses four connections with color-coded leads, which keeps wiring clear at the drive end. The insulation system is qualified for 340 VDC, allowing the windings to operate with higher bus voltages used by modern current-controlled drives. A square Size 34 frame, measuring about 8.5 cm, keeps the motor compatible with common mounting footprints while concentrating magnetic flux in a compact body.

Radial loading at the center of the shaft is limited to 65 lbs, which supports pulleys, gears, and similar mechanical elements when the overhung load stays within that limit. Power is transferred through a straight keyway shaft, giving a secure mechanical connection to hubs and gears without slip. Continuous phase current reaches 2.8 A, making the motor suitable for chopper drives that regulate winding current to control heat and torque. The housing is drilled for NEMA through holes, so the motor mounts flush to panels or adapter plates. No rear add-ons are installed, which leaves open space at the back of the motor for applications that need additional clearance.
