Product Description:
The CTM32NLF46KAA00 is a hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. The unit belongs to the Cool Torque Maximum family and is intended for positioning tasks where incremental motion is governed by open-loop pulse counts. By delivering 200 full steps per revolution at a 1.8° step angle, the motor allows repeatable indexing of conveyors, pick-and-place axes, or metering pumps in industrial automation.
When both phases are energized, the rotor can resist external rotation with 1350 oz-in of holding torque, enabling stable load support at standstill. Each winding draws a rated phase current of 4.6 A DC, and this current flows through 1.01 Ω of resistance to produce the magnetic field needed for torque. Dynamic response is influenced by the coil inductance of 7.1 mH, which affects how quickly current rises as command pulses arrive. The housing uses a Size 34 / 8.5 cm frame, so it fits NEMA 34 gearboxes and brackets. Four leads exit the body for bipolar drive connection, and the 96.5 mm stack length helps the motor fit compact enclosures without sacrificing torque density.
The rotor’s stored kinetic energy corresponds to a moment of inertia of 2.61 kg-cm², giving predictable acceleration when paired with a suitable micro-stepping drive. Mechanical integrity is supported by an allowable axial shaft load of 100 lbs (45 kg) in either direction and a radial load capacity of 65 lbs (29 kg) at the shaft center, allowing belt tension or pinion overhang without premature bearing wear. Total mass is 3.0 kg, which helps limit moving weight on gantry axes. The motor also uses a straight-keyed 12.7 mm shaft, has 41 oz-in of detent torque, and a thermal resistance of 1.55 °C/W that helps keep winding temperature within the limits of its 340 VDC insulation rating.
