Product Description:

The CTP11ELS13MAA00 stepper motor is manufactured by Kollmorgen as part of the CT Stepper Motors series. It belongs to the Cool Torque Performance Series and has the High Torque Performance characteristic set, which emphasizes high output in a compact frame. The motor converts pulse trains into repeatable rotary motion for machine axes, dispensers, and material-handling fixtures in industrial automation. English tapped mounting holes let the unit fasten directly to panels or brackets, and the low-voltage windings suit systems powered by micro-stepping DC drives.

The frame measures Size 17 / 4.2 cm, and each electrical cycle produces a mechanical step of 1.8°, yielding 200 full steps per revolution for predictable indexing. A bipolar holding torque of 0.44 N-m holds loads in place when motion is paused. Electrical parameters include a phase resistance of 3.31 Ω, a phase inductance of 3.4 mH, and a rated winding current of 1.3 A DC; these values affect driver voltage selection and current ripple. The coils reach nominal torque at 4.4 V DC, and the thermal resistance is 5.44 °C/W for continuous duty. Six lead wires allow series or parallel connection, and the motor uses a 5.000 mm metric shaft supported by a front bearing set.

Mechanical loading limits protect the bearings: axial forces up to 6 lbs push / 15 lbs pull and a radial load of 15 lbs at shaft center are acceptable. Dynamic response is aided by a rotor inertia of 0.00075 oz-in-s², and the assembly weight is only 0.26 kg. The single-stack lamination keeps the overall length short, and no rear shaft configuration is supplied. Insulation resistance is 100 MΩ at 80 V DC, and the mounting thread pattern is 4 × UNC #4-40 2B. The metric shaft simplifies coupling to precision pulleys or gears.
