Product Description:

The CTP10ELS12MAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series in the Cool Torque Performance line. This short-stack Size 17 motor is intended for precise open-loop positioning and incremental motion tasks in industrial automation where compact dimensions and strong torque density are required. English tapped mounting holes, a metric output shaft, and six-lead wiring make the motor straightforward to install in equipment that follows North American or international mechanical practices. The combination of mixed mounting standards also helps it fit assemblies that use both inch-based and metric components.

The motor delivers a bipolar holding capability of 0.30 N-m, while the drive electronics must supply up to 1.2 A DC per phase for rated operation. A phase resistance of 3.38 Ω ±10% limits voltage drop, and with 4.2 VDC applied, the winding reaches the current rating without excessive heating. Dynamic response is influenced by the phase inductance of 2.40 mH, which affects current rise during microstepped operation and helps determine how quickly torque builds after a command change. Each full step advances the rotor by 1.8°, giving 200 discrete positions per revolution, and step accuracy is held within ±5%. Unipolar holding torque reaches 0.23 N-m, and the winding system has an insulation rating of 80 VDC with an insulation resistance of 100 MΩ. Six discrete leads support either series or parallel winding connections, while detent torque remains limited to 0.014 N-m when the phases are de-energized.

The housing length is only 34.7 mm, yet the motor withstands 6 lb push and 15 lb pull axial loads plus a 15 lb radial load at the shaft center. The ground output shaft measures 5.00 mm in diameter and uses a metric profile suited for couplings or timing pulleys, while the low rotor inertia supports rapid acceleration in light gantry stages and other compact axes. A thermal path of 6.21 °C/W helps the Cool Torque design shed heat during continuous duty. Net weight is 0.20 kg, and rear add-ons are omitted to keep the package compact where clearance behind the motor is limited.
