Pacific Scientific acquired the Sigma company, which was among the first ever to produce stepper motors commercially, long ago. Since then, they have also been acquired by the Kollmorgen technological conglomerate, and for good reason: their patented Sigmax technology and innovative, deeply customizable motor designs have defined the automation industry for decades. Even to this day, Pacific Scientific’s E31NRHT-LNN-NS-00 model stepper motor is a stiff competitor in the 3.4 inch diameter or NEMA 34 size frame category, and a time-tested choice for a deep pool of applications.
Among the most notable features of the E31NRHT-LNN-NS-00 configuration of Pacific Scientific stepper motors is the excellent torque output of the T-type winding. This specialized winding type offers maximum torque at minimum speed, but retains the capacity for precise high speed motion too. A laminated rotor and standard smooth shaft design set the E31NRHT-LNN-NS-00 up for success with maximum power input to work output efficiency by minimizing power losses. Configured in 4-lead parallel, the E31NRHT-LNN-NS-00 puts all 5.4 amps DC of its rated current to high-yield application with an operating torque of up to 349 ounce-inches.
This motor is precise to within 1.5% of a singular 1.8 degree step, and resists slippage with a holding torque of 337 ounce-inches to ensure that your final product is manufactured with the same brand of excellence with which your Pacific Scientific equipment has been. With a low rotor inertia and thermal resistance, as well as a comfortable band of operating tolerances, the E31NRHT-LNN-NS-00 is designed to ensure that exactly what you tell it to do is what gets done: it can start and stop almost instantaneously, does so with minimal power loss to heat, and easily tolerates its own heat generation when properly installed.
