Product Description:
The H33NLEC-LNW-NS-00 is a stepping motor produced by Kollmorgen for the H Hybrid Motors series. As a hybrid stepper, it converts pulse commands from an indexer or motion card into fixed angular increments. This operation provides open-loop positioning for pick-and-place axes, small conveyors, and metering pumps in industrial automation.
The rotor advances 1.8 degrees per full step, so a complete revolution requires 200 steps. Positioning repeatability remains within ±1.5%, supporting applications that need moderate precision without feedback. The motor uses 3 laminated magnetic stacks to increase torque while keeping rotor inertia reasonable. A NEMA 34 frame provides a standardized mounting footprint, and the mounting holes follow the corresponding NEMA thread locations. The stator and end bells use standard construction, while the smooth cylindrical shaft accepts couplings that clamp radially. Six leads exit the stator, allowing the drive to connect the coils in series or parallel according to the required torque and speed characteristics. These conductors pass through a splash-proof conduit connector and terminate on an internal board. The conduit entry accepts a 1/2-inch NPS pipe thread, allowing rigid metal conduit to protect the wiring in areas exposed to occasional moisture or splashing.
The windings use Class B insulation rated for 130 °C, providing thermal protection during continuous motor operation. The insulation resistance is 100 megohms at 500 V when measured with a megohmmeter, helping prevent leakage current between the windings and motor housing. The motor withstands up to 340 VDC, providing electrical headroom for compatible high-bus microstepping drives. Continuous operation is permitted from -20 °C to +40 °C, allowing the motor to function in unconditioned enclosures and lightly heated machinery within this temperature range. The splash-proof conduit connection helps keep moisture away from the conductor terminations. Proper conduit sealing and strain relief also reduce mechanical stress on the six motor leads during installation and operation.
