Product Description:

The E34HLHA-LNS-NS-02 hybrid stepper motor belongs to the E Hybrid Stepper Motors series from Kollmorgen and is used for indexing, positioning, and feed axes in automated machinery. SIGMAX construction channels magnetic flux into the rotor teeth, and the heavy-duty mounting style mates with standard brackets. A smooth shaft simplifies coupler installation, while the splash-proof conduit connection protects the terminal board. The conduit fitting uses a 1/2-inch NPS thread. Without a feedback device, the motor executes commands through open-loop control.

The motor delivers a holding torque of 8.83 Nm, keeping loads stationary when the coils are energized. Its square housing follows the NEMA 34 frame standard, so it shares a 3.4-inch face with many compatible gearheads. Each phase draws up to 8.1 A, while the 0.29 Ω phase resistance limits copper loss at that current. A step angle of 1.8 degrees produces 200 discrete steps per revolution, and a step accuracy of ±1.5% helps maintain registration in feeders or labelers. Four parallel leads support connection to bipolar drives. The four-stack rotor increases torque density for applications that require substantial holding force within the available frame size.

Phase inductance is 3.6 mH, providing a short electrical time constant for responsive microstepping control. The motor operates within a temperature range of -20 °C to +40 °C. Its Class B insulation rated for 130 °C protects the windings under elevated internal temperatures, while a 340 V DC dielectric rating provides resistance to electrical surges. An insulation resistance of 100 megohms limits leakage current between the windings and the laminated core. A thermal resistance of 1.7 °C/W indicates the temperature rise associated with each watt of dissipated power. These electrical and thermal limits should be observed during continuous operation to prevent excessive winding temperature and preserve consistent stepping performance under load.
