Product Description:

The CTP12ELF26MAA00 is a hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. As a two-phase unit from the Cool Torque Performance line, it provides incremental rotary motion for indexers, pick-and-place heads, and other positioning axes in industrial automation. Its discrete step operation often eliminates the need for separate feedback devices in medium-torque applications, which helps simplify wiring and control architecture. Because the shaft advances in fixed increments, the motor can synchronize easily with pulse-and-direction controllers used in compact automation platforms. That makes it practical for repeatable indexing tasks where motion must be predictable without the added complexity of a servo feedback loop.

Under bipolar excitation, the motor develops 0.56 N-m of holding and running torque and moves in increments of 1.8 degrees per step, so standard pulse trains can advance the shaft in predictable angular steps. Each winding draws 2.6 A DC at standstill, and a winding resistance of 1.09 ohms supports controlled current rise while keeping copper losses manageable. Mechanical speed can reach 3000 rpm, which gives the motor enough range for fast linear travel when it is coupled to lead screws, belts, or similar transmission elements. In many stepper systems, that combination supports short moves, dwell cycles, and frequent start-stop operation without requiring encoder feedback. These operating values suit applications that need clear step positioning, straightforward drive matching, and dependable low-speed control.

The motor body has an overall depth of 48.3 mm, and the Size 17 frame measures 42.7 mm square to support compatibility with common mounting patterns. Its mass is only 0.34 kg, which helps limit moving-axis load on gantries, slides, and compact robotic assemblies. Heat leaves the laminations through a thermal path rated at 4.71 C/W, so natural convection is usually adequate in normal room-temperature service. The compact housing also helps in tightly spaced machine sections where axis spacing and moving mass affect acceleration and support design. The class B insulation system withstands up to 80 VDC between the windings and frame, which supports use with many low-voltage micro-stepping drives while maintaining electrical isolation.
