Product Description:

The CTP31NLS35KAA00 is a hybrid stepper motor produced by Kollmorgen as part of the CT Stepper Motors series. It is intended for high-torque positioning tasks in packaging equipment, pick-and-place axes, and other discrete-motion stations. The motor uses a Size 34 (8.5 cm) frame and a single-stack configuration, giving it a compact body. Its 1.8° step angle provides 200 full steps per revolution, while a straight keyway shaft and six lead wires support common bipolar or unipolar drive arrangements. Because power is delivered through leads rather than a connector, cable routing can remain simple in tight machine layouts.

The motor's minimum holding torque is 437 oz-in, allowing it to restrain static loads without closed-loop feedback. During motion, the winding produces 4.0 N·m of bipolar torque, while detent torque stays at 22 oz-in to support smooth microstepping. It has a phase current rating of 3.5 A, a phase resistance of 1.29 ohms, and a phase inductance of 4.9 mH. The phase voltage is 4.5 VDC, and the windings withstand 340 VDC continuously and 500 VAC for one second with an insulation resistance of 100 megohms. These electrical values support responsive operation with compatible stepper controls. A rotor inertia of 0.0185 oz-in-s² supports rapid acceleration.

The shaft can withstand axial forces up to 100 lbs in either direction and radial loads of 65 lbs at the center line, which suits belt drives and indexing mechanisms. A shaft diameter of 0.5000 in matches standard half-inch couplings, and the 2.875-inch pilot helps locate the housing on NEMA through-hole mounts. The motor weighs 4.0 lb and uses AWG 22 lead wires for connection. It is supplied without rear add-ons, which helps keep overall enclosure depth low. This format is useful where clearance behind the motor is limited.
