Product Description:
The E34HRHP-LNK-NS-00 is a motor manufactured by Kollmorgen and included in the E Hybrid Stepper Motors series. Designed for incremental motion control, it converts digital pulse trains from indexers or drives into precise shaft positions. This controlled movement suits conveyors, gantries, and packaging equipment that require repeatable positioning in industrial automation.
It occupies a NEMA 34 frame, so the mounting holes align with common heavy-duty NEMA flanges. Its SIGMAX magnetic construction raises flux density to produce a 1300 oz-in holding torque that resists shaft movement while the motor is energized at standstill. Each winding draws 7.7 A at standstill, while a phase resistance of 0.33 Ω helps limit copper loss. The stored winding energy is managed by a phase inductance of 4.4 mH, which moderates the current rise. Axial and radial shaft loads are limited to 180 lb and 96 lb, respectively, to protect the shaft bearings. Class B insulation is rated for 130 °C, the insulation resistance is 100 MΩ, and the dielectric withstand rating is 340 VDC. The stator has a thermal resistance of 1.7 °C/W, and the electrical connection uses four parallel leads.
Bipolar drive sequences advance the rotor in increments of 1.8 degrees, providing 200 full steps per revolution. The step accuracy is ± 1.5 %, which keeps indexing errors within typical machine tolerances. The four-stack lamination geometry works with a rotor inertia of 0.035 oz-in-s² and a winding optimized for maximum torque at high speed, supporting rapid acceleration without missed steps. The motor operates within an ambient temperature range of -20 °C to +40 °C, and its 9.7 lb mass helps transfer heat during continuous operation. A smooth shaft accepts clamping couplings for spur gears or timing pulleys without requiring a keyed interface.
