Product Description:

The CTP11ELS09MAA00 is a hybrid stepper motor produced by Kollmorgen for the CT Stepper Motors series. Classified within the Cool Torque Performance Series, the unit provides discrete angular positioning for indexing, metering, and incremental feed axes in industrial automation. It converts commanded pulse trains into fixed mechanical steps for open-loop motion without an encoder while maintaining the high torque profile associated with this product family. This style of motor is commonly used where repeatable indexing is needed and closed-loop feedback is not required by the application. Its hybrid construction supports stable low-speed positioning and simple pulse-driven control.

A phase current of 0.85 A interacts with a phase resistance of 8.02 Ω to generate winding I²R loss that is dissipated through the 5.44 °C/W thermal path. The coil value of 8.0 mH influences the current rise rate during microstepping. At the shaft, the motor can deliver 0.44 N·m of bipolar holding torque, and each electrical cycle advances the rotor by 1.8°. Six lead wires provide full-step, half-step, or unipolar connection options to match different drive topologies. These electrical values influence drive selection, current regulation, and low-speed smoothness during incremental moves. They also affect how the motor responds when pulse rates change during start and stop sequences.

Frame size 17, a metric 5 mm diameter output shaft, and a 20.07 mm shaft extension support compact couplings, while inch-threaded front holes allow direct mounting. Rotor inertia is 0.0000053 kg·m² and the stack length is one, which supports rapid start-stop response while keeping total mass to 0.26 kg. Axial loading is limited to 6 lb push and 15 lb pull, with a 15 lb radial limit at the shaft center. Insulation resistance is rated at 100 Megohms, and the windings withstand 80 VDC. The open rear configuration and six-lead construction leave clearance for couplings and cable routing. The low mass and short stack help the motor respond quickly in compact assemblies with limited mounting space.
