Product Description:

The S31GNNA-RNNM-00 serves as one brushless motor featuring a NEMA 34 enclosure chassis that weighs roughly 3.2 kg. As a component of their S Motors line (Brushless), Pacific Scientific manufactured it. It has a sustained torque of (stall) 2.2 Nm. This motor comes with a resolver (frameless) of size 21. It is used for main/primary feedback. The S31GNNA-RNNM-00 from Pacific Scientific is a high-performance servo brushless motor from their S lineup, engineered to generate robust torque despite its compact footprint. Designed to provide continuous torques ranging from 0.5 to 6.6 Nm, this motor is ideal for demanding motion control applications where both power and space efficiency are critical.

This servo model features a NEMA 34/1 stack frame size, ensuring standard compatibility and facilitating straightforward integration into existing systems. The Pacific Scientific S31GNNA-RNNM-00 is available with both metric and NEMA 23 & 34 mounting faces, offering flexibility in installation and supporting a broad range of application requirements. The motor’s terminations are managed via a motor-mounted MS connector, which ensures secure and efficient electrical connections.

For precise motion control and feedback, the S31GNNA-RNNM-00 utilizes a Size 21 (Twenty one) frameless resolver as its primary feedback device. Notably, this servo module does not incorporate a secondary feedback or a holding brake. The servo motor leverages the advanced S Series 6 pole (Six pole) Neodymium construction, which provides high torque density and long-lasting durability. With its rugged build and advanced feedback capabilities, the S31GNNA-RNNM-00 is an excellent solution for a wide range of industrial automation and motion control needs, delivering dependable performance and easy integration. The S31GNNA-RNNM-00 brushless motor is ideal for any type of industrial task.
