Product Description:

The PMX3410-D10-BF0-00 is a hybrid stepper motor manufactured by Kollmorgen within the PMX Stepper Motors series. The unit produces incremental motion that follows pulse commands from motion controllers. This allows open-loop positioning for feeders, indexing tables, and small gantry axes where repeatable holding torque is needed without an encoder. Because encoder feedback is not required, the motor suits straightforward motion tasks that rely on commanded step pulses for position control.

The electrical interface is a 4-lead bipolar arrangement, so each phase is brought out on two leads and driven by an H-bridge for full-step or half-step sequences. Internally, it uses a bipolar winding, meaning the coils can be energized with current in either direction to reverse the magnetic field and increase torque density. This layout lets the drive alternate current direction in each phase to advance or hold the rotor at commanded positions. Housing size matches NEMA frame code 34, which uses a 3.4-inch square mounting pattern that fits many legacy machine brackets. Position resolution is set by a step angle of 1.8°; 200 full steps complete one shaft revolution, and microstepping drives can interpolate smaller increments if smoother motion is required. Mechanical output is confined to the front because the motor has no rear shaft, which shortens the overall length and removes the option for a secondary encoder or handwheel.

The motor ships with the flat shaft option, providing a machined flat that helps prevent coupling slippage under pulsed load changes. This gives set-screw or clamp-style couplings a more secure contact surface in many applications. Magnetic length is listed as 1 stack, giving a single lamination stack that balances holding torque with lower inertia for faster start-stop cycles. It is a standard motor without a shaft seal, so applications should avoid liquid ingress or use external guarding in washdown areas.
