Product Description:

The CTM22NLF69NAA00 is a size-23 hybrid stepper motor from Kollmorgen in the CT Stepper Motors series. It is part of the Cool Torque Maximum line and uses an enhanced design intended to deliver high torque with efficient operation in a compact frame. The motor converts sequential stator energization into precise motion, producing 1.8 ° mechanical steps for open-loop positioning in pick-and-place heads, gantry slides, metering pumps, and similar automated equipment.

In electrical operation, the motor draws a rated per-phase current of 6.9 A DC through four color-coded leads. Each phase has a resistance of 0.28 Ω and a typical inductance of 0.81 mH, which supports short electrical time constants and responsive current control. A full revolution is divided into 200 steps, and the ±3% step accuracy helps maintain repeatable positioning during indexing sequences. Rotor inertia is 0.0068 oz-in-s², which supports fast starts and stops without excessive lag. At standstill, the motor delivers 3.32 N·m of holding torque, while the detent torque is 22 oz-in. The NEMA 23 frame measures 5.7 cm square and uses a two-stack lamination to keep torque density high without adding unnecessary bulk.

For operating conditions, the motor is rated for an ambient range of −20 °C to +40 °C. Insulation is rated at 100 MΩ and 340 VDC, while a thermal resistance of 2.62 °C/W supports predictable temperature rise under load. The round smooth shaft can withstand 50 lb of axial thrust and 20 lb of radial load at the shaft center, and the NEMA through-hole mounting style helps align the motor on brackets or gearboxes. The motor has no rear shaft extension, which keeps overall depth minimal and leaves the cable exit unobstructed.
