Product Description:

The S31GMNA-RNNM-00 brushless motor has a NEMA 34 frame size, a weight of 3.2 kg, and a constant stall torque of 2.2 Nm. The Pacific Scientific S Brushless Motors family includes this one. It has a size 21 frameless resolver for feedback and a max torque of 6.2 Nm. The Pacific Scientific S Series S31GMNA-RNNM-00 is a strong brushless servo motor. This servo motor has been designed to work well and be flexible in a broad variety of industrial motion management applications.

This type has a torque range (continuous) of 0.5 to 6.6 Nm, making it perfect for tough manufacturing settings. This brushless servo is ideal for settings that need both power and efficiency. The NEMA 34/1 stack frame size and metric mounting choices make this servo motor easy to install. Installation is particularly easy for systems with either metric or NEMA 24 & 23 mounting panel faces. Its small size lets it provide a lot of torque. Despite the small size, it can generate a significant amount of torque. Furthermore, this servo motor saves space on the machine. The S31GMNA-RNNM-00 does not have a holding brake, thus it is perfect for situations where rotation has to happen all the time without stopping. It has a motor-mounted MS connector for electrical connections, which makes sure that the terminations are safe and work well.

A size 21 frameless resolver gives the motor the most important input. This feedback is accurate and dependable, which allows for precise control. There is no secondary feedback or shaft seal in this variant. The S31GMNA-RNNM-00 is part of the S Series 6-pole Neodymium range. It uses cutting-edge magnetic technology and Pacific Scientific's reputation for quality and performance to make it a reliable choice for both new and retrofit industrial automation applications.
