Pacific Scientific E42HLHB-LNK-NS-00 Stepping Motor

Pacific Scientific Sigma E42HLHB-LNK-NS-00 is a two-stack, SigMax hybrid step motor in a NEMA 42 frame (4.28 in diameter) that delivers precise 1.8-degree steps from a two-phase coil arrangement. This no-feedback motor uses a four-lead parallel winding, laminated rotor, and a single, keyed shaft with splash-proof construction for rugged OEM environments. Verified specifications include a maximum speed of 1,500 RPM, an operating current of 7.9 A, and a DC bus voltage of 160 V (±10%). The torque range is listed as 1,805–2,698 oz-in (12.75–19.06 Nm), and the unit weighs approximately 19.1 lb. It employs a two-stack rotor design characteristic of higher torque output in a compact form factor within the SigMax family of Pacific Scientific stepping motors.
