Product Description:

The CTP10ELF10MAA00 is a hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. As a member of the Cool Torque Performance Series, the unit provides incremental motion for indexing tables, medical pumps, and light pick-and-place axes where repeatable positioning is required. It converts digital pulse trains from a drive into fixed angular steps, allowing open-loop speed and position control without shaft-mounted feedback, which simplifies wiring in distributed industrial automation systems.

With a bipolar holding torque of 0.30 N-m, the motor can maintain position against moderate process loads. Two-phase windings draw a rated phase current of 1.0 A, and the copper coils present 5.25 ohms of DC resistance at 40 °C, a value that influences supply voltage and heat generation. The electrical time constant is governed by a winding inductance of 7.7 mH, so current rise is controlled and microstep linearity is preserved at higher speeds. A 1.8° mechanical step angle yields 200 full steps per revolution, giving controllers integer pulse counts for travel increments. Four leads permit series or parallel bipolar wiring, and the motor’s two-phase architecture ensures balanced electromagnetic fields during operation.

Mechanically, the motor uses a short stack lamination that keeps mass low while allowing an axial shaft load of 6 lbs push / 15 lbs pull and a permissible radial load of 15 lbs at the shaft center. The Size 17, 4.2 cm frame with English-tapped mounting holes aligns to NEMA-style brackets, and a 5 mm metric shaft that extends 20.07 mm simplifies coupling to pulleys or screws. Rotor inertia is 0.0000036 kg-m², enabling acceleration with minimal overshoot. Insulation is rated for 80 VDC, and thermal resistance of 6.21 °C/W informs heat sink sizing when duty cycles are prolonged. Step positioning remains within ±5% of nominal, and with no rear add-ons the housing clears tight equipment envelopes while still delivering the high torque performance characteristic noted for this series.
