Product Description:

The H32NCHA-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. As a two-phase, multi-stack unit, it delivers incremental motion for indexing tables, dispensers, and medium-torque actuators that do not require encoder feedback. The motor’s smooth shaft couples to timing pulleys or lead screws, while its NEMA mounting pattern allows substitution for legacy stepper motors without mechanical changes.

This model advances one full step every 1.8 degrees, yielding 200 discrete positions per revolution and a published step accuracy of ±1.5%. A holding torque of 3.14 N-m resists back-driving when the coils are energized, and the four-lead parallel winding draws 5.6 A per phase through a System MS connector. Electrical losses remain moderate because the copper path shows only 0.39 Ω of resistance and 4.1 mH of inductance, allowing current to rise quickly for rapid detent-to-detent moves. Two rotor stacks and a rotor inertia of 0.120 ×10⁻³ kg·m² balance damping with responsiveness, while Class B insulation, a 340 Vdc dielectric rating, and 100 MΩ of insulation resistance protect the windings against thermal and leakage faults. Thermal resistance is 2.7 °C/W, so external heat sinking may be added when duty cycles push phase current toward its continuous limit.

The motor’s cast frame follows the NEMA 34 envelope, weighs 2.40 kg, and supports radial loads up to 156 N and axial loads up to 801 N on the smooth shaft without premature bearing wear. Operability is maintained from -20 °C to +40 °C, matching typical factory conditions, while the standard construction and NEMA mounting pattern support straightforward integration. A four-lead parallel connection simplifies wiring inside drive enclosures, and the absence of feedback eliminates additional controller cable runs. The System MS plug supports a secure electrical connection, and the motor is suited for conveyors, pick-and-place heads, and light gantry axes where vibration is common.
