Product Description

The S31GMNH-RNNE-00 from Pacific Scientific is a high-performance brushless servo motor made for precise tasks in industrial automation. This NEMA 34 frame motor is part of the SENTRY Series. The motor has a 6-pole neodymium design that makes it stable and effective. Due to its small size and sturdy construction, this motor is designed to meet strict needs and can be easily integrated into high-tech motion control systems.

With a continuous stall torque of 0.95 Nm and a peak torque of 3.82 Nm, the S31GMNH-RNNE-00 brushless servo motor has more than enough power for dynamic uses. The torque constant (Kt) of 0.627 Nm/A makes sure that the motor output is precisely controlled, and the back EMF constant (Ke) of 0.44 Vrms/kRPM makes it more efficient. The motor has a Viton shaft seal that makes it last even in tough circumstances. The servo motor has a rotating inertia of 0.00027 kg·m², which means it can quickly speed up or slow down. The rear-facing MS connector for input and metric mounting makes installation and integration easier. The design is simplified if a brake or secondary input is not required, as they are not included. The motor's weight of 4.1 kg and Winding Type G make it even smaller and more efficient.

A size 21 frameless resolver in the S31GMNH-RNNE-00 brushless servo motor makes sure that the input is correct that is needed for precise motion control. The terminal box's positioning is intended to facilitate wiring and maintenance. Because of its high power output and small size, the motor is perfect for tasks that need to be reliable and accurate. The device demonstrates Pacific Scientific's commitment to developing cutting-edge motion solutions that are adaptable to the changing needs of modern robotic systems
