Product Description:

The R65GENA-NP-RW-VS-02 is developed by Pacific Scientific with a built-in Viton seal for shaft protection and to achieve rating of category IP65 from pollutants. It belongs to the R60 series of motors and comes with a total length of 11.36 inches. This motor delivers a peak torque of 45 Nm by utilizing 82 A of peak current.

The R65GENA-NP-RW-VS-02 servo motor is presented without a feedback system but extends its supports for advance encoders such as Tachsyn, Hall sensors and resolver feedback, which can be attached according to the requirement of machine system. It generates a continuous torque output specified at 13 Nm and it take 36 minutes of time to stabilize thermal value by half the temperature reached, through its provided heatsink of size 18” x 18” x 1/2”. The R65GENA servo motor possess 1.8 Ohm of hot-resistance across the line-line terminals and 1.20 Ohms at 20°C. It is designed in accordance with English standards for shaft and installation style. This motor is enclosed in a rugged frame size of 5.75 inches, that come in square shape and it features an anti-cog design to provide smooth operations at high/low speeds. Its viscous coefficient is rated as 0.075 Nm/Krpm and has an angular moment of inertia 0.00124 kg·m², along with a constant of voltage 117 V/Krpm.

The R65GENA-NP-RW-VS-02 servo motor is equipped with long life bearings that are front locked with steel inserts and their rear side is held tight by O-rings. It offers a static friction equivalent to 0.26 Nm and its thermal impedance is measured as 0.42 °C/Watt. The R65GENA servo motor has a weight of 18 kg and it gets power through the provided convenient MS-type connector.
