Product Description

Pacific Scientific manufactures a variety of servo motors that come in different frame sizes and include the highest standards of technology and design. Their brushless design ensures remarkably diminished wear and tear and hence low maintenance downtime. They are further classified under various sub-series and R20 is one such series that includes some of the most powerful motors with excellent features. They come in 5 Frame Sizes ranging from 2 to 7.5 square inches in the Continuous Torque Range of 0.32 to 50 Nm.

The R21HENA-R1-NS-NV-01 belongs to this R20 series. It is constructed using rare earth Samarium-Cobalt permanent magnets with a compatible matching magnetic stack. The mounting is standard English factory assigned and the standard shaft with no sealing rings. As indicated in the part number, it has the factory named “H” category of winding and add-on module feature. It has a transmitter type, size-15 standard frameless resolver for providing primary feedback and no provision for the secondary auto-feedback. The sequence number in the part nomenclature indicates flying-leads closings with standard open-standing MS connectors.

Like all R20 series servo motors, R21HENA-R1-NS-NV-01 is lightweight and easy to use. It has a well designed light frame and a high torque to weight ratio which give it the rugged and powerful characteristic. Besides this, it also displays a smooth performance over variable speed, thanks to its anti-cog stator design.

The Pacific Scientific devices have comprehensive design combinations to cater to all type of user’s requirements. All these motors are designed keeping the best of safety and control protocols and hence provides an ideal solution to be used in various applications in the power industry.
