S21GNNA-RNNL-00 Image 1


The S21GNNA-RNNL-00 is a servo motor in the S Motor Series by Pacific Scientific. This particular motor utilizes Neodymium magnets, known for their high torque to inertia ratio, a vital attribute in modern machining processes such as drilling, printing, and boring. The product boasts a peak torque of 1.36Nm and a rated speed of approximately 12500 RPM. A notable feature of the S21GNNA-RNNL-00 is its size 21 frameless resolver sensor, which controls and monitors the rotation degree of machine components. On top of this, the servo motor also employs hall sensors to supervise the machinery's position, speed, and current. Weighing a mere 1.4kg and designed especially for compact spaces, this lightweight motor is easily transportable within or outside various industrial settings. This product additionally stands out for its robust, non-sealed output shaft, specifically built from high-quality material to withstand substantial stress without bending or fracture. The S21GNNA-RNNL-00's frame is constructed in line with NEMA 23 standards, offering protection against a variety of environmental factors including heat, dust, and water. Furthermore, this frame is designed to prevent electrical currents from making contact with the user, increasing safety. However, the S21GNNA-RNNL-00 is designed for horizontal usage due to the absence of a holding brake. To extend its lifespan and improve durability, Pacific Scientific suggests using an external fused wire with the servo motor.

S21GNNA-RNNL-00 by Pacific Scientific is a Brushless Servo Motor in the S Series. The S21GNNA-RNNL-00 features a Frame Size/Stack Length of NEMA 23/1 Stack and a Holding Brake Option of No Brake. This Brushless Servo Motor also has a Size 21 Frameless Resolver for Primary Feedback and a Secondary Feedback of No Secondary. Additional specifications include a NEMA Frame for Shaft & Mounting and a 18 Flying Leads for Terminations.
