Product Description:

The CTP11ELS03MAA00 is a two-phase stepper motor manufactured by Kollmorgen as part of the CT Stepper Motors series. It is positioned in the Cool Torque Performance line within the High Torque Performance classification. The motor converts pulse commands from a drive into incremental rotation, supplying open-loop position control for indexing tables, pick-and-place heads, and other light industrial axes. Because it advances in repeatable step increments, it can handle straightforward positioning duties without a separate feedback device in many applications.

During bipolar drive mode, the motor delivers 0.44 N-m of holding torque while each phase draws 0.35 A at stall. The electrical circuit has a 47 mH phase inductance and 48.1 Ω of phase resistance, which affect current rise time and the drive voltage needed for operation. Thermal performance includes a 5.44 °C/W winding-to-ambient thermal resistance, which helps keep the windings within insulation limits at the specified current. The rotor uses a single-stack construction with 0.0000053 kg·m² of inertia for rapid acceleration, and a 1.8° step angle divides each revolution into precise increments. Six flying leads also simplify series or parallel wiring with drives that accept six-wire connections.

It tolerates an axial push of 6 lbs and a pull of 15 lbs, and the radial capacity at the shaft center is the same. Resolution is fixed at 200 full steps per revolution, matching drives that issue standard step pulses. Electrical insulation is supported by 100 Megohms of resistance and a withstanding potential of 80 VDC, which suits low-voltage motion platforms. The NEMA Size 17 frame measures 42 mm square and mounts through English-tapped holes. A 5 mm metric shaft that is 20.07 mm long exits the front, the rear face has no additional devices, and the lead wires provide the electrical connection style.
