Product Description:

The E32NLHT-LNF-NS-01 hybrid stepper motor is produced by Kollmorgen as part of the E Hybrid Stepper Motors series. Built with SIGMAX construction and a smooth shaft, it delivers discrete positioning for indexing tables, pick-and-place units, and other open-loop automation axes. This layout is useful in compact equipment that needs predictable step-by-step motion. The unit mounts on NEMA hardware, accepts conduit wiring through a 1/2 in. NPS pipe thread connector, and uses a splash-proof termination board for protected electrical connections. Because it is intended for open-loop step motion, no external feedback device is required for basic indexing service. With a weight of 2.40 kg and an overall length of 121.2 mm, it suits machinery where installation space and moving mass are limited.

Electrically, the motor uses 4-lead parallel windings that draw 5.2 A per phase and have 5.0 mH of phase inductance, a combination chosen for maximum torque in low-speed duty cycles. In operation, it holds 4.65 Nm of static torque and moves in 1.8 degrees per step, which yields 200 discrete positions per revolution with an accuracy of ±1.5%. The two stator stacks are housed in a NEMA 34 frame, and heat is dissipated through 2.7 °C/W thermal resistance. Continuous service is permitted in ambient temperatures from -20 °C to +40 °C, and the bearings support a radial load of 156 N during belt-driven service. The insulation system withstands 340 VDC and maintains 100 megohms to ground, which helps preserve electrical isolation during operation.

Mechanically, the rotor inertia is 0.120 x 10^-3 kg·m², which supports quick reversals without demanding excessive drive torque. A shaft seal helps block contaminants, and the shaft can withstand an axial thrust of 801 N. The copper windings have a phase resistance of 0.44 Ohms, matched to the thermal margin of Class B, 130 °C insulation. That combination supports extended holding and low-speed operation where winding heat must remain under control.
