Product Description:

The Pacific Scientific S22HSNA-RNNM-03 motor can handle a peak torque of 2.64 Nm and a constant torque (stall) of 1.0 Nm. This is one of Pacific Scientific's S Brushless Motors. The S22HSNA-RNNM-03 features a frameless resolver feedback system and can handle a line-to-line inductance of 5.7 mH. The S22HSNA-RNNM-03 from the manufacturer Pacific Scientific is a flexible and strong servo motor, which is part of the S Series. It was made to generate a lot of torque in a tiny space. This motor can handle continuous torques from 0.5 to 6.6 Nm. It is designed for tough industrial applications where motion control is important and performance and dependability are key. The frame size of this model is NEMA 23.

The frame has a length of two stacks. This frame operates with typical installation arrangements in both NEMA 23, metric, and 34 systems. This makes the first setup less stressful. The S22HSNA-RNNM-03 comes with a MS connector (motor-mounted) that establishes electrical connections safer, making it easy to add to control systems. The motor uses a Size 21 resolver (frameless) as its main feedback mechanism to make sure that it can accurately and reliably sense its location.

This servo type doesn't include a secondary feedback option or a holding brake option, therefore it's great for situations where continuous motion is the most important thing. This S Series servo motor has a 6-pole (Six pole) Neodymium magnet design that makes it very efficient, has a lot of torque density, and lasts a long time. It can handle a wide variety of industrial automation jobs. The S22HSNA-RNNM-03 is of course a great option for industrial applications that require high-performance, dependable motion management in a small size. This module doesn't have any supplementary feedback.
