Product Description:

Pacific Scientific makes the S31ANNH-RNNM-00 motor. This is a high voltage, NEMA 34-frame-sized motor from the S Brushless Motors family. The motor has a torque of (stall) 2.2 Nm and cools itself naturally via convection. It weights 3.2 kg (kilograms) (7.055 lb. or 112.88 oz). The S31ANNH-RNNM-00 from Pacific Scientific is a high performance brushless servo motor from the S Series. It has been designed and manufactured by Pacific Scientific.

It is designed to provide consistent torque and accuracy in a small package. With constant torques between 0.5 and 6.6 Nm, this motor is perfect for motion control applications that need both power and economy. When referring to economy, it indicates cost saving. This product has a NEMA 34/1 frame size for the stack, which makes this module compatible with a wide array of installation and setup needs and typical mounting faces. Both the metric & NEMA 23 as well as 34 are among these available mounting faces. The tiny size of the design "squeezes" a lot of torque output into a small box, making the most of space without losing performance.

The S31ANNH-RNNM-00 comes with a shaft and mounting configuration that is set up at the factory. Its motor mounted MS connection makes it simple and safe to attach electrical wires. This model has a Size 21 frameless resolver as its main feedback device, which gives accurate and reliable position feedback. This edition doesn't come with a auxiliary feedback system or any holding brake. The S31ANNH-RNNM-00 is made using Pacific Scientific's famous 6-pole Neodymium magnet structure, which gives it great efficiency, strong torque density, and long-lasting dependability. This makes it a flexible and affordable choice for many different types of industrial automation and motion control systems.
