Product Description:

The E33HCHP-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. Built on a NEMA 34 frame, it uses SIGMAX construction to concentrate magnetic flux and increase torque density. The unit connects to drive electronics through a System MS connector, and its heavy-duty NEMA mounting face supports installation in established machinery. This model is intended for open-loop or microstepped positioning stages where repeatable rotary increments translate into linear motion for packaging, semiconductor, or inspection equipment.

The motor has a holding torque of 995 oz-in, allowing the shaft to resist a load while energized without an external brake. Each full step measures 1.8 degrees, so one electrical revolution provides 200 discrete positions. Controller interpolation can further subdivide these increments, while the base step accuracy remains ±1.5% for indexing applications where cumulative error must remain low. The four-lead parallel winding draws 7.9 A per phase and has a resistance of 0.26 Ω, making it suitable for low-voltage, high-current microstep drives. Three internal stator stacks work with a rotor inertia of 0.025 oz-in-s² to balance torque production and response time, while the maximum-torque-at-high-speed winding profile maintains usable output above typical mid-band resonance.

Heat dissipation is supported by a thermal resistance of 2.0 °C/W, while a phase inductance of 3.1 mH permits rapid current changes without excessive voltage spikes. The electrical insulation has a rating of Class B at 130 °C, provides 100 megohms of insulation resistance, and withstands up to 340 VDC between the windings and frame in grounded systems. Continuous operation is permitted at ambient temperatures from -20 °C to +40 °C. A smooth shaft with a diameter of 0.5000 in simplifies coupling to gearheads or pulleys while allowing the user to select the preferred alignment method.
