The E21NRFT-LSS-NS-02 stepper motor from Pacific Scientific is a highly specialized model of its Sigmax conventional hybrid style of motor. It features a customized shaft configuration as well as special modifications applied to the shaft itself in order to suit your purpose-built project needs. In addition to its focused, innovative design, this Pacific Scientific stepper provides the unparalleled performance that put Pacific Scientific at the top of the automation supply industry for many years.
Among the many qualities of the E21NRFT-LSS-NS-02 are its integrated NEMA mounting, NEMA 23 housing size (2.3 inch diameter), and regular hookups with 8 leads. Its highest rated current, which occurs in the parallel lead arrangement, is a mere 2.8 amps DC. Switching to serial leads drops this to only 1.39. In return, in either configuration the motor is capable of providing a holding torque of 123 ounce-inches, while generating minimal heat and power loss due to the precision engineering present in all Pacific Scientific products.
From -20 degrees Celsius to 40 degrees Celsius, or -4 Fahrenheit to 104 degrees Fahrenheit, the E21NRFT-LSS-NS-02 has an error margin of, at absolute maximum, 1.5% of a single step. A very low rotor inertia and industry-standard steps of 1.8 degrees give you the accuracy and repeatability you need for high-end automatic manufacturing. Finally, its maximum operating torque is 126 ounce-inches which gives it an excellent weight-to-torque ratio considering that it weighs only 1.2 pounds, or .55 kilograms. If you have a project in need of the E21NRFT-LSS-NS-02 and its specialized shaft design, you can rest easy knowing that the platform on which your customized shaft is mounted is robust, economical, and reliable in a wide range of operating conditions.
