Product Description:

The PMX1750-G10-UN0-00 is a hybrid stepper motor produced by Kollmorgen and assigned to the PMX Stepper Motors series. Classified in the manufacturer’s Stepper Motor Series product group, it converts digital step commands into controlled angular movement for pick-and-place heads, syringe pumps, and other low-to-medium inertia loads in industrial automation. Its 17-frame construction keeps the motor compact while still delivering the discrete step positioning needed wherever simple open-loop motion is preferred over closed-loop servo control.

Each electrical transition advances the rotor by a precise 1.8°, a value that defines the resolution of the motion profile. The housing follows the NEMA 17 frame outline, so it mounts directly to standardized gearboxes or linear stages. A five-stack rotor increases detent flux, allowing a 0.535 Nm holding torque without energizing beyond the rated phase current. That continuous current requirement is 1.03 A per phase, and it pairs with a copper winding impedance of 5.81 Ω phase resistance to establish driver voltage selection and power dissipation. Thermal resistance of 4.78 °C/W characterizes the temperature rise between the stator and ambient air, while the unipolar or bipolar winding option lets designers trade speed for torque by choosing the appropriate drive topology. A smooth front shaft, specified as an option, simplifies the installation of press-fit pulleys or couplings.

Mechanical loading limits reach 10 N axial load limit and 28 N radial load limit, suitable for light belt tensions or modest thrust collars. Power is routed through a 6-lead bipolar connection, so the phases can be wired in series or left in separate half-coils for higher speed operation. The shaft end uses a smooth front shaft interface, and there is no rear extension, eliminating additional bearings. The motor is delivered as a standard unit without a shaft seal, an arrangement adequate for clean-equipment zones where ingress protection beyond the motor frame is provided by the host machine enclosure.
