Product Description:

The CTM32NLS36KAA00 is a hybrid stepper motor produced by Kollmorgen as part of the CT Stepper Motors series. Designed to deliver precise incremental motion for indexing tables, material feeders, and similar automation axes, the unit belongs to the Cool Torque Maximum line. By combining a size-34 frame with a two-stack magnetic core, it provides high holding torque within the standard NEMA footprint used on many machine frames.

The motor operates on two phases that draw 3.6 A per phase from a 5.8 VDC supply. Copper windings present a phase resistance of 1.63 Ω and a phase inductance of 6.0 mH; this electrical profile affects the time constant and the driver voltage needed during rapid stepping. Bipolar holding torque reaches 9.5 N-m, while detent torque is limited to 0.29 N-m so the rotor can index without excessive static drag. Each full step advances by 1.8°, and six lead connections allow either series or parallel bipolar winding configurations. Leads are provided instead of a connector, which simplifies routing through cable tracks. The motor mounts with NEMA through-holes, and its 8.5 cm square flange supports the two-stack stator height without exceeding common enclosure depths. The Cool Torque Maximum name indicates an internal lamination design that increases torque density and efficiency.

Mechanical loading includes an axial limit of 100 lbs (45 kg) in either direction and a radial limit of 65 lbs (29 kg) at the shaft center, values that suit the straight shaft with a keyway used for rigid couplings. Rotor inertia is 2.61 kg-cm², giving predictable acceleration profiles when paired with micro-stepping drives. Positional accuracy stays within ±3%, and heat generated in the windings exits through a thermal path rated at 1.55 °C/W. Electrical insulation withstands 340 VDC and has 100 MΩ resistance, helping maintain dielectric integrity under high-energy switching. The motor has no rear accessory configuration, which keeps the overall length shorter.
