Product Description:
The E33NSHT-LNN-N6-02 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. It converts indexed pulse commands from a drive into incremental shaft movement, making it suitable for positioning tables, pick-and-place heads, and metering pumps in automated equipment. The motor occupies a NEMA 34 frame, so its front-face dimensions align with common 3.4-inch mounting patterns used on machinery and gearboxes.
The internal windings use Class B insulation rated for 130 °C, allowing continuous thermal loading without damaging the enamel coatings. Insulation resistance between the coils and frame is rated at 100 megaohms, reducing leakage current when chopper amplifiers drive the windings. During hipot testing, the insulation can withstand up to 340 VDC. Power is supplied through a 4-lead parallel connection, which provides lower effective inductance and supports a responsive current rise. The rotor-stator interface uses Kollmorgen’s SIGMAX construction to improve flux density, while the three-stack magnetic circuit increases holding torque without enlarging the frame. A smooth shaft connects to zero-backlash couplings. NEMA-style flange holes simplify installation on compatible mounting surfaces.
Each electrical cycle advances the rotor by 1.8 degrees, yielding 200 discrete positions per revolution for deterministic indexing without an encoder. The specified operating temperature range of -20 °C to +40 °C supports use in unheated warehouses and enclosed cabinets. Positional error remains within ± 1.5% of the nominal step, supporting applications that require repeatable movement but not servo-grade accuracy. The three-stack topology concentrates magnetic flux at low speed, while the winding is optimized for maximum starting and holding torque. The motor can maintain holding torque during dwell periods without requiring additional gearing.
