Product Description:

The E33HRFT-LNK-NS-00 is a hybrid stepper motor built by Kollmorgen within the E Hybrid Stepper Motors series. As a two-phase, open-loop positioning element, it converts command pulses into angular motion for indexers, packaging actuators, and gantry axes that do not require feedback devices. The motor integrates SIGMAX magnetic construction and a smooth shaft so that torque density is increased while vibration is reduced during precise incremental moves. This design suits motion systems that rely on repeatable pulse-based positioning with a straightforward electrical interface.

The frame conforms to the NEMA 34 footprint, allowing installation in standardized mounts. A holding torque of 6.89 N·m helps the motor resist external load movement at standstill. Each full step advances the rotor by 1.8 degrees, giving predictable angular resolution without micro-stepping. In parallel wiring, the windings draw 5.1 A, a current level that supports stronger torque at higher shaft speeds. When wired in series, the coils exhibit a total inductance of 28.2 mH, which is better suited to applications that favor lower driver ripple and cooler running.

The motor completes a full turn in 200 steps per revolution, a count that aligns with common controller pulse outputs and simplifies ratio calculations. Continuous service is supported between -20 °C and +40 °C, matching typical enclosure environments without forced cooling. Internal insulation is rated at Class B 130 °C, and the motor has 100 MΩ insulation resistance with a 340 Vdc withstand rating to limit leakage under drive voltage. Overall housing length is contained to 5.33 in, which helps when retrofitting into limited machine cavities. Additional details include an eight-lead, 22 AWG harness for series or parallel connection, a heavy-duty NEMA flange, three rotor stacks that raise low-speed torque, and a step accuracy of ±1.5% for repeatable indexing.
