Product Description:

The CTP11ELF11MAA00 is a two-phase stepper motor manufactured by Kollmorgen as part of the CT Stepper Motors series. It is intended for Cool Torque Performance applications such as indexing devices, small conveyors, and laboratory automation systems that need repeatable open-loop positioning. By energizing the stator windings in sequence, the motor advances the shaft in controlled increments so that PLCs and drive amplifiers can move light loads accurately in packaging, semiconductor handling, and similar equipment.

Under bipolar drive, the motor delivers 0.44 N-m of running torque, which is suitable for holding or advancing small linear stages. This output is reached at 1.1 A DC with a winding voltage drop of 5.5 VDC. The phase resistance is 5.19 Ω, which contributes to steady-state electrical losses, and the winding inductance of 11 mH affects current rise during microstepping. The motor has 200 full steps per revolution, and its single-stack construction supports axial loads of 6 lb (2.7 kg) in push and 15 lb (6.8 kg) in pull, along with a 15 lb (6.8 kg) radial load at the shaft center. A 5 mm metric shaft and four lead wires support straightforward integration, while English tapped holes allow convenient NEMA-style mounting.

Detent torque is limited to 0.018 N-m, which helps keep unpowered holding friction low. The rotor inertia is 0.05 kg-cm², allowing quick acceleration in compact motion systems, and the thermal resistance of 5.44 °C/W indicates the rate at which heat is transferred through the case. The motor uses a compact Size 17 / 4.2 cm frame, weighs 0.26 kg, and is supplied without a rear shaft. Insulation resistance is 100 MΩ, and the windings withstand 80 VDC. Metric shaft geometry, single-stack construction, and leaded connections make the unit easy to fit into tightly packed equipment.
