Product Description:

The E34HLLT-LNK-NS-01 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. This four-stack unit converts pulse trains from an indexer or microstepping drive into controlled rotary increments, providing open-loop positioning for conveyors, dispensers, and small gantry axes. SIGMAX magnetic construction concentrates flux in the stator teeth, while a smooth shaft transfers torque without the backlash associated with gear reduction.

Its static holding torque reaches 1240 oz-in when the windings receive rated current, helping the motor hold machinery in position at standstill. Each command pulse rotates the shaft by 1.8°, so 200 pulses complete one mechanical revolution for predictable incremental moves. The windings draw 5.2 A per phase at standstill, and the coil resistance is 0.71 Ω. These electrical values help with drive selection and indicate the winding losses produced during continuous operation. Electromagnetic energy is stored in the lamination stack with a phase inductance of 8.7 mH, which shapes the electrical time constant and influences how quickly current rises during rapid acceleration.

The motor uses a NEMA 34 frame, providing standardized face dimensions and a 3.875 in bolt circle for direct attachment to heavy-duty mounts. Its body measures 7.62 inches in overall length and has 0.218-inch mounting holes, while the 0.5-inch smooth shaft supports a radial load of 96 pounds. Thermal characteristics include a thermal resistance of 1.7 °C/W and an ambient operating range of -20 °C to +40 °C, supporting the Class B insulation system rated for 130 °C. The motor weighs 9.7 lb, and its rotor inertia of 0.035 oz-in-s² helps reduce microstep oscillations without placing excessive load on smaller linear guides. Four splash-resistant leads simplify connection to conduit-terminated terminal boards and help protect the electrical connections in industrial machinery.
