Product Description:

The CTP10ELS05MAA00 is a hybrid stepper motor produced by Kollmorgen and aligned with the CT Stepper Motors series. It is part of the Cool Torque Performance Series and translates digital pulse trains into accurate angular motion for compact material-handling or metering stations in automated equipment. By combining a short magnetic stack with a metric output shaft, the motor offers high torque density while remaining light enough for direct mounting on small frames.

The motor has a bipolar holding torque of 0.30 N·m, which is enough to index lightweight loads without mechanical backlash. The windings draw only 0.5 A at a rated supply of 9.9 VDC, limiting heat rise and allowing simple drive electronics. With two stator phases arranged in a six-lead configuration, the rotor advances in 200 full steps per revolution. Each step spans 1.8°, and cumulative position variation is limited to ±5%, giving repeatable motion for optical tables and syringe pumps. Axial loading is rated at 6 lb in push and 15 lb in pull, so thrust screws may be coupled directly to the shaft. Detent torque of 0.014 N·m supports open-loop stability between moves, while radial capacity reaches 15 lb when the force is applied at the shaft center.

At just 0.20 kg, the frame 17 housing measures 4.2 cm square, which helps keep inertia low, and the rotor adds 0.04 kg-cm² to support rapid acceleration for short-stroke axes. Heat travels through a thermal path of 6.21 °C/W. Class B insulation is supported by an insulation resistance of 100 MΩ and a dielectric withstand of 80 VDC. Electrical parameters include a winding resistance of 19.4 Ω and an inductance of 13 mH, which suit micro-stepping drives that use six-lead connections in either a unipolar or bipolar scheme. Installation is aided by English-tapped mounting holes, a metric shaft, and an open rear stack for coupler or encoder additions.
