Product Description:

The CTP12ELF10MAA00 is a hybrid stepper motor from Kollmorgen for incremental positioning in automated stages, indexers, and other compact motion systems. It belongs to the CT Stepper Motors series and is also linked internally to the Cool Torque Performance line, which emphasizes high torque density in a compact frame. In operation, the motor converts command pulses into fixed angular movement for repeatable open-loop positioning. Its hybrid stepper design suits applications that need simple pulse-based control and consistent indexing over short, repeated moves.

The motor delivers a bipolar holding torque of 0.56 N-m and draws a rated phase current of 1.0 A. The windings operate at 6.6 VDC, with a phase inductance of 12 mH and a phase resistance of 6.51 Ω, which influence current rise and speed response. Two identical phases use four color-coded leads for connection to standard bipolar stepper drives, making the electrical interface straightforward. Rotor inertia is 7.5 × 10⁻⁵ kg·m², and the 2-stack lamination helps the motor handle frequent start-stop indexing with controlled overshoot. Electrical isolation includes 100 MΩ insulation resistance and an 80 VDC withstand voltage, helping reduce leakage to grounded metal housings during normal installation.

Each revolution is divided into 200 full steps, which gives a step angle of 1.8°. The shaft diameter is 5.000 mm, and it supports radial loads of up to 15 lb at the shaft center along with axial forces of 6 lb push or 15 lb pull. English tapped holes on the Size 17 (42 mm) face simplify front mounting to NEMA fixtures, and the lack of rear hardware helps the body fit in tighter spaces. Four lead wires exit the housing for crimp or solder termination, which supports flexible connection methods in compact assemblies. The thermal path is characterized by 4.71 °C/W, allowing predictable temperature rise during operation.
