Product Description:

The E33hrha-Lnk-Ns-00 is a hybrid stepper motor built by Kollmorgen for the E Hybrid Stepper Motors series. It uses SIGMAX construction and a three-stack rotor to deliver high torque with precise positioning in automated indexers, pick-and-place heads, and small gantry axes. The motor converts open-loop step commands into discrete shaft movements that can be interpolated by microstepping drives for smoother motion. Its hybrid magnetic design supports accurate incremental movement without requiring a position sensor for basic open-loop applications.

Its NEMA 34 frame footprint provides a mounting face compatible with standard motor brackets, while the rotor inertia of 0.177 × 10^-3 kg·m² limits overshoot during start-stop cycles. A holding torque of 6.64 N·m resists external loads at standstill. Each phase draws 8.6 A through a low phase resistance of 0.23 Ω, producing a rapid current rise despite the 2.3 mH phase inductance. The motor advances in 1.8-degree steps, providing 200 discrete positions per revolution with a step accuracy of ±1.5%. The laminated SIGMAX structure concentrates magnetic flux to increase shear torque without enlarging the frame. An axial load of up to 801 N can be applied when couplings or pulleys are clamped directly to the shaft.

The smooth 12.7 mm shaft accepts compression collars or clamping hubs while tolerating a radial load of 427 N at the front bearing. The maximum housing length is 135.4 mm, and the assembled motor weighs 3.45 kg, allowing placement inside compact machinery without excessive structural load. Heat produced in the windings dissipates through a thermal path rated at 2.0 °C/W, and continuous operation is permitted from -20 °C to +40 °C. Class B insulation withstands winding hot-spot temperatures up to 130 °C. The electrical insulation system also provides resistance of 100 MΩ and dielectric strength of 340 VDC to protect the windings from drive-related voltage transients.
