Product Description:
The E33NCHP-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. The unit combines the detent stability of a permanent-magnet rotor with the fine resolution of a variable-reluctance design, delivering discrete position control for indexing tables, pick-and-place gantries, and similar automation axes. It accepts open-loop or microstepping drive signals and translates each electrical pulse into a fixed mechanical increment, giving machine builders a straightforward method for generating repeatable rotary motion without feedback hardware.
The motor has a NEMA 34 frame, and its mounting face follows the same NEMA pattern for direct interchange with legacy hardware. SIGMAX construction and a three-stack magnetic core produce a holding torque of 7.03 Nm, allowing static load retention without brake hardware. Rotor inertia is 0.177 × 10⁻³ kg·m², so acceleration demands remain moderate. The two-phase winding has a phase inductance of 3.1 mH and a phase resistance of 0.26 ohms. It operates at a rated current of 7.9 A when wired in the specified four-lead parallel configuration. The Class B insulation is rated for 130 °C and has an insulation resistance of 100 megohms and a dielectric rating of 340 VDC. Thermal resistance is 2.0 °C/W, which supports heat dissipation during operation. Allowable axial thrust reaches 801 N, matching typical lead screw loads for vertical axes, and the winding is optimized for maximum torque at high speed.
The motor operates from -20 °C to +40 °C and weighs 3.45 kg, which simplifies handling during machine assembly. Power connections terminate through a System MS connector, and the motor presents four parallel leads to minimize copper losses. A smooth shaft transmits motion while withstanding a radial bearing load of 156 N. A standard step angle of 1.8 degrees provides 200 full steps per revolution with a step accuracy of ±1.5%, keeping positional error low without encoder feedback. The parallel lead arrangement supports the electrical requirements of the dedicated high-speed winding while providing a direct connection to a compatible stepper drive.
