Product Description:

H33NLHC-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen as part of the H Hybrid Motors series. As a NEMA 34 frame motor, it combines detent torque with electrical excitation to produce discrete position increments for indexing tables, pick-and-place axes, and motion stages in industrial automation. The designation identifies a three-stack configuration within the product family.

With a holding torque of 4.65 Nm, the motor can maintain position under load when its coils are energized. Each phase draws 11.1 A at rated conditions, and the low phase resistance of 0.15 ohms together with a phase inductance of 1.6 mH allows current to rise quickly for good torque response at moderate pulse frequencies. The three rotor and stator stacks increase magnetic flux while keeping thermal rise manageable. The motor has a thermal resistance of 2.0 °C/W, uses Class B insulation rated to 130 °C, and has a voltage limit of 340 Vdc. Axial thrust of up to 801 N can be applied without exceeding bearing limits, and the terminal-board connection is splash-proof through a 1/2-inch NPS conduit adapter.

Side loading capability reaches 156 N, allowing timing pulleys or couplings to be mounted on the smooth shaft without premature bearing wear. Each step advances the rotor by 1.8 degrees, so one revolution is divided into 200 equal increments, and a step accuracy of ±1.5% supports repeatable indexing in medium-precision machinery. Rotor inertia is 0.177 × 10⁻³ kg·m², which helps the motor accelerate quickly when used with microstepping drives. The four parallel leads support phase termination options, the operating ambient temperature range is -20 °C to +40 °C, and the overall mass is 3.45 kg, which keeps the unit manageable for gantry or mobile platforms with limited payload.
