Pacific Scientific was a company with a reputation for quality and cost-efficient equipment, both in terms of the purchase price and the operating costs you will have to contend with. Their reputation was so great, in fact, that over 15 years ago the brand and technology were acquired by Kollmorgen, a giant in the automation industry who still produces rebranded Pacific Scientific designs. Their stepper motors, originally created by one of the first two companies ever to manufacture stepper motors at all, were improved upon through the long history of the Sigma corporation, which was later acquired by Pacific Scientific, who continued to fine tune their motors to excellence.
The E21NRFT-LNN-NS-00 is a general-purpose Pacific Scientific step motor featuring a laminated rotor driven using an 8-lead configuration and a single rotor stack. The laminated rotor reduces magnetic losses in your device, further enhancing the efficiency of this finely tuned automation equipment. This motor is accurate to within 1.5% of one step even in the harshest conditions permitted by its wide range of operating parameters.
It utilizes Pacific Scientific’s proprietary Sigmax technology, which gives it world-class torque for a motor of its size. This particular configuration also offers its maximum torque in low-speed applications, yet can still provide the speed you need for rapid movement purposes. Despite its low magnetic losses and potential for very rapid motion, the holding torque of the E21NRFT-LNN-NS-00 does not suffer in the slightest--it offers up to 123 ounce-inches, depending on your choice of lead configuration. If efficiency, rapidity, repeatability, and proportionally top-notch torque suit the needs of your automation project, the Pacific Scientific E21NRFT-LNN-NS-00 is the stepper motor for you.
