Product Description:
The E33HRHS-LNS-NS-02 hybrid stepper motor is manufactured by Kollmorgen as part of the E Hybrid Stepper Motors series. It operates without internal feedback and relies on digital pulse commands from a microstepping drive to index the rotor, providing repeatable open-loop positioning for automation stages, labeling heads, and metering pumps. A standard lead-wire connection simplifies field wiring, while a smooth shaft allows direct coupling to pulleys, gears, or flexible couplers without secondary machining.
The motor’s frame conforms to NEMA 34, and the outside stator diameter measures 3.38 in. These characteristics support heavy-duty flange mounting on standard machinery plates. Each full step moves the rotor by 1.8 degrees, resulting in 200 increments per revolution and providing fine motion granularity for step-indexed profiles. Positional repeatability is supported by a step accuracy of ±1.5%. Three rotor-stator stacks increase detent and pull-out torque, while a four-lead parallel winding provides low phase inductance for drives that must achieve high slew rates.
The winding uses Class B insulation rated for 130 °C, permitting continuous service when the coil temperature remains below that limit. An insulation resistance of 100 megohms under ambient conditions minimizes leakage current, while a withstand voltage rating of 340 V DC protects the phase circuitry against drive-induced transients. Proprietary SIGMAX construction concentrates magnetic flux to increase torque without enlarging the frame. The permitted operating temperature ranges from −20 °C to +40 °C, accommodating many indoor industrial environments without auxiliary thermal conditioning. A laminated rotor reduces eddy-current losses during rapid stepping and helps limit unnecessary heat generation within the motor. Heavy-duty mounting lugs resist frame distortion when the motor is secured to a rigid machine plate.
