Product Description:
The E22NSFB-LNN-NS-04-1 hybrid stepper motor is manufactured by Kollmorgen as a member of the E Hybrid Stepper Motors series. The unit converts sequential current pulses from a microstepping drive into discrete rotor movements, allowing efficient motion control in pick-and-place heads, labeling stations, and small conveyors. In industrial automation, it delivers predictable holding torque and position repeatability without requiring the feedback circuitry used by servo platforms. Its standardized mounting interface allows straightforward integration into compatible machine layouts and motion assemblies.
The motor follows the NEMA 23 frame standard, so its face, pilot, and bolt circle align with other 2.3-inch motors that use the same NEMA mounting style. Each full command pulse turns the rotor by 1.8 degrees, providing 200 steps per revolution for incremental positioning. Its full-step accuracy is ±1.5%, supporting repeatable open-loop movement when the motor operates within its available torque range. An 8-lead wiring harness supports series, parallel, or unipolar connection arrangements. Dual magnetic stacks provide the higher torque associated with a two-stack design. SIGMAX construction directs magnetic flux efficiently across the rotor teeth, while the smooth shaft accommodates gears, pulleys, and flexible couplings.
The windings use a Class B insulation system rated to 130 °C, so the copper temperature must remain below this limit during continuous operation. Insulation resistance is at least 100 megohms under ambient test conditions, helping protect the windings from leakage current. The insulation has a dielectric withstand rating of 340 VDC, providing resistance to electrical stress from the connected drive. The permitted operating temperature range is -20 °C to +40 °C, which accommodates typical indoor factory environments without auxiliary heating or cooling. Proper drive-current settings and adequate airflow around the housing help prevent excessive winding temperatures during extended operation. The motor should also be protected from moisture and contaminants that could reduce insulation performance or interfere with shaft movement.
