Product Description:

The E34HRFT-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen as part of the E Hybrid Stepper Motors series. Within an automation cell, this motor receives controlled pulse trains from a microstepping drive and converts them into fixed angular increments, giving machinery a practical way to achieve precise positioning without an encoder. Its laminated rotor and permanent-magnet stator work together to provide holding capability and rapid incremental movement for indexing tables, pick-and-place heads, and packaging feed systems.

The rotor advances in fixed increments of 1.8 degrees, so one full rotation is divided into 200 individual steps. Position repeatability is maintained within a ±1.5% window, and the motor provides a detent torque of 0.59 N·m that resists external disturbance when de-energized. Because the rotor inertia is only 0.247 × 10⁻³ kg·m², start-stop sequences can be executed with minimal overshoot. Four internal stator stacks combine with the max-torque-at-low-speed winding design and SIGMAX construction to increase low-speed pull-out torque. The square NEMA 34 frame has a body length of 162.14 mm, a thermal resistance to ambient of 1.7 °C/W, and a weight of 4.41 kg, so heat generated during duty cycles is transferred quickly to the mounting surface.

Eight conductors exit the housing through a regular leadwire bundle, and the harness extends at least 304.8 mm while using a minimum of 22 AWG copper to support series or parallel phase wiring. The insulation system is rated Class B at 130 °C, maintains an insulation resistance of 100 megohms, and tolerates a dielectric test voltage of 340 Vdc. Continuous service is supported across an ambient range of -20 °C to +40 °C without degradation. Installation uses the heavy-duty NEMA pattern with a 98.43 mm bolt circle and 5.46 mm holes, while the smooth shaft simplifies coupling to gears or pulleys. The eight-lead configuration also allows bipolar or unipolar drive connections for flexible torque-speed tuning.
