Product Description:
The E22NRLP-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen for the E Hybrid Stepper Motors series. Supplied as a motion element for incremental positioning, it converts pulse sequences from a stepper drive into controlled shaft rotation for pick-and-place modules, small conveyors, and metering pumps in automated equipment. SIGMAX construction channels magnetic flux efficiently through the two-stack geometry to support high torque at elevated operating speeds.
The motor fits the NEMA 23 frame code, and its laminated rotor advances by 1.8 degrees per full step. Power enters through a 4-lead series harness that supports a bipolar connection without separate connector blocks. Thermal protection is provided by Class B, 130 °C insulation, which withstands the winding temperatures associated with demanding operating cycles. An insulation resistance of 100 megohms helps isolate the coils from the motor housing. The smooth, unsealed shaft minimizes friction, while the regular lead wire connection style eases routing inside confined control cabinets. A NEMA mounting pattern supports installation on compatible machine frames without requiring a custom mounting plate. The motor does not include a feedback device, making it suitable for open-loop applications in which the controller tracks position through commanded step pulses.
Full-step operation yields 200 discrete rotor positions per revolution, allowing precise indexing without microstepping. Positional error remains within ±1.5 %, which is suitable for many material-handling stages that do not require encoder correction. The insulation system tolerates a hipot test of 340 VDC, providing a safety margin against voltage transients from the connected drive. The permitted ambient temperature range is -20 °C to +40 °C, allowing operation in unconditioned enclosures and climate-controlled production cells without auxiliary heating or cooling. The 2.25-inch body dimension fits within compact machinery where lateral space is limited, and the motor can be paired with a compatible stepper drive for controlled incremental movement.
