Product Description:

The CTP12ELS08MAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series. It is part of the Cool Torque Performance line and is intended to deliver high torque from a compact frame without requiring closed-loop feedback. Each command pulse moves the rotor by a fixed increment, making the motor suitable for indexing tables, syringe pumps, and miniature conveyors that need repeatable positioning with simple drive electronics. This open-loop design is useful where accurate incremental motion is needed without the added complexity of encoder-based control.

The motor provides a bipolar holding torque of 0.56 N-m. That output is achieved when both phases receive the rated winding current of 0.82 A DC, and the winding characteristics include a phase inductance of 9.2 mH and a phase resistance of 10.1 ohms. These electrical values influence current rise and the applied voltage needed for stable phase excitation. The total motor length is 48.3 mm, which helps keep the unit compact, while the 0.34 kg mass and 4.71 °C/W thermal resistance support continuous-duty operation.

Mechanical integration uses English-tapped front face holes and six lead wires for phase connections, which helps simplify wiring inside control cabinets. The rotor completes 200 full steps per revolution with a theoretical step angle of 1.8° and an accuracy of ±5 percent, supporting fine resolution when microstepping is added. A Size 17 frame in a 2-stack configuration has a metric shaft with a 5 mm shaft diameter and a length of 20.07 mm, allowing direct coupling to pulleys or spur gears. Axial loading is limited to 2.7 kg push and 6.8 kg pull, while a 6.8 kg radial load may be applied at the shaft center. Insulation withstands 80 V DC with 100 MΩ resistance, and no rear add-ons are fitted so the back face remains clear for tight installations. This layout can be useful where the motor is mounted close to adjacent components or enclosure walls.
