Product Description:

The E33HRFP-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen as part of the E Hybrid Stepper Motors series. The unit converts digital pulse trains from an indexer or PLC into precise rotary motion for automated cutters, small conveyors, and metering pumps where open-loop positional repeatability is acceptable. Its hybrid stepper design suits repeatable indexing tasks that rely on simple command pulses instead of closed-loop servo feedback. It uses eight flying leads for flexible series or parallel wiring, and the smooth shaft simplifies coupler alignment in automated equipment.

The motor is built on a NEMA 34 frame that measures 3.38 in in diameter and 5.33 in in overall length, allowing installation on heavy-duty NEMA mounts. Each full step advances the rotor by 1.8 degrees, and with 200 full steps per revolution, the device delivers predictable incremental motion without an encoder. A three-stack rotor design and SIGMAX construction concentrate flux so the shaft can withstand an axial thrust of 180 lb (801 N) and a radial side load of 96 lb (427 N) without accelerated bearing wear. The windings use insulation rated at Class B, 130 °C, and the declared 100 MΩ insulation resistance helps prevent dielectric breakdown during high-duty cycles.

An insulation voltage rating of 340 Vdc permits use with drives that apply high bus voltages to maximize dynamic torque, while operation across -20 °C to +40 °C supports installation in unconditioned factory spaces. The motor has a mass of 3.45 kg, which helps damp torsional resonance at low speeds and supports thermal stability within the insulation class. A regular lead-wire connection style supports straightforward wiring in control cabinets and on machine frames. This arrangement is useful where panel space is limited and where the motor must be connected without special feedback hardware.
