Product Description:
The E33NRFC-LNN-NS-00 hybrid stepper motor is manufactured by Kollmorgen as part of the E Hybrid Stepper Motors series. It is a two-phase motor built on the NEMA 34 frame that provides open-loop indexable motion for material-handling stations, pick-and-place axes, and other mid-torque automation tasks. By energizing its stator phases in sequence, the rotor advances in equal increments, letting a motion controller position a load without encoder feedback when inertia and friction are predictable. The hybrid design combines toothed rotor geometry with permanent-magnet behavior, which helps the motor deliver stable incremental movement and useful holding torque at standstill.
Each electrical pulse rotates the shaft by a 1.8-degree increment, so a full 360° turn requires 200 discrete steps. The shaft itself measures 0.3750 in in diameter, allowing direct coupling to timing pulleys or flexible couplings sized for small power-transmission hardware. Stator laminations and rotor magnets fit within a 3.38 in body diameter that matches the stated bolt circle and pilot features on the mounting face. The motor uses a Class B, 130 °C insulation system that withstands sustained winding temperatures while maintaining dielectric strength. With a published step accuracy of ±1.5%, the motor can provide repeatable positioning when current and loading remain within its operating limits.
The motor operates between -20 °C and +40 °C, allowing installation on machinery frames exposed to typical plant temperatures. Inter-winding separation is verified for up to 340 Vdc, so most micro-stepping drives can apply higher bus voltages for better torque-speed curves. An 8-lead connection scheme is brought out on 12 inches of insulated lead wire, making series, parallel, or unipolar configurations possible without internal changes. This wiring flexibility lets the motor be matched to different current and inductance requirements without changing the internal winding arrangement. Overall stack length reaches 5.06 in, and the three-stack SIGMAX rotor construction increases torque density compared with shorter units in the same frame.
