Product Description:

The E33HRFC-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the E Hybrid Stepper Motors series. As a two-phase device that indexes a fixed number of full steps per electrical cycle, it is used in industrial automation to position machine tables, valves, and small process actuators with repeatable accuracy without requiring a feedback device. This operating style suits indexing applications that need predictable stopping positions and straightforward drive control. Its heavy-duty NEMA mounting pattern supports installation in machine frames that use this mounting format.

Mechanical output is anchored by a holding torque of 927 oz-in, which is suitable for medium-inertia loads that need position retention at standstill. The motor advances in full-step increments of 1.8 degrees, yielding 200 discrete steps per revolution, and step accuracy remains within ±1.5% so indexing errors stay within normal process tolerances. The frame conforms to the NEMA 34 footprint, and SIGMAX construction increases flux density across the 3-stack rotor. An 8-lead regular lead-wire connection allows series or parallel phase wiring, while Class B insulation rated for 130 °C is paired with a 340 Vdc dielectric rating. The motor operates reliably in ambient temperatures from -20 °C to +40 °C without derating.

The cylindrical housing diameter measures 3.38 in, and its length plus stack count contribute to a rotor inertia of 0.025 oz-in-s². This combination of low inertia and high holding torque supports quick start-stop motion with limited overshoot in indexing service. At only 7.6 lb, the motor is well suited for axes where moving mass must be kept low. Insulation resistance is rated at 100 Megohms, indicating solid dielectric separation after thermal cycling. The motor has a single smooth shaft without a seal, and the heavy-duty mounting flange helps align the housing during installation.
