Product Description:
The CTM22NLS19NAA00 is a stepper motor manufactured by Kollmorgen within the CT Stepper Motors series for open-loop positioning in industrial equipment. Positioned in the Cool Torque Maximum Series subgroup, it supplies high static torque for axes that advance in fixed increments. The unit translates command pulses from a matched drive into controlled rotary steps used by conveyors, dispensers, and compact machine tools.
Internally, the rotor-stator geometry yields a 1.8° step angle, so the shaft advances 200 positions per electrical revolution, and this resolution aids indexers that do not use encoders. The CTM winding provides 3.32 N-m holding torque, while 0.16 N-m detent torque stabilizes the rotor when power is removed. A Size 23 frame that is 84.3 mm long and uses two lamination stacks fits into tight machine spaces yet retains magnetic path length for torque production. Electrical limits include a phase current of 1.9 A, a resistance of 3.39 Ω, and an inductance of 5.9 mH, a combination chosen to balance copper loss and current rise time. Rotor inertia of 0.48 kg-cm² limits overshoot during rapid reversals, and the Enhanced Series characteristic indicates that the thermal design and winding pattern are optimized to boost torque and efficiency.
Mechanical loading limits complement the electrical ratings. The shaft tolerates 50 lbs (23 kg) axially and 20 lbs (9 kg) radially at the center, allowing direct-coupled pulleys or lead screws. A rated supply of 6.4 VDC matches the winding resistance for full torque without excessive I²R heating, and the thermal path to ambient is characterized by 2.62 °C/W. Six pre-tinned leads simplify series or parallel phase wiring, and the housing mounts through standardized NEMA through-holes. A round 6.35 mm smooth shaft avoids key-seat stress points, while rear extensions are omitted to reduce length. Dielectric integrity is supported by 100 Megohms of insulation resistance at 340 VDC test voltage. Net mass of 1.13 kg and the specified connection count support gantry carriages where weight and cable routing matter.
