Product Description:
The R65GENA-TS-SS-NV-02 Servo motor offers accurate and stable motion control in industrial automation machinery. The rotor mass moment of inertia is specified at 1.24 × 10⁻³ kg·m². The motor has a net weight of 18 kg. This servo motor is made by Pacific Scientific. The back EMF constant of the motor is 1.12 V·s/rad.
The R65GENA-TS-SS-NV-02 servo motor features a square frame of 146 mm. It has a total body length of 288.5 mm without a brake. When the optional brake unit is installed, the overall length extends to 356.1 mm. The shaft diameter of the motor is 28.56 mm. The mounting bolt circle measures 149.2 mm to support the standard mechanical interfaces. The maximum static friction is 0.26 Nm. However, the viscous friction coefficient is 0.075 Nm·s/rad. This ensures a controlled response at varying speeds. The R65GENA-TS-SS-NV-02 servo motor housing meets IP65 protection, excluding the shaft end. The construction meets NEMA MG1-1.26 Part E sealing standards. The thermal resistance of the unit is 0.42 °C/W. However, the thermal time constant is 36 minutes. This supports safe and efficient heat dissipation. The Phase-to-phase resistance is 1.20 ohms when cold. This resistance elevates to 1.81 ohms when hot.
The R65GENA-TS-SS-NV-02 servo motor uses Winding G. It provides a continuous stall torque of 13 Nm. The motor supports a maximum torque of 45 Nm. The torque coefficient of the motor is 1.12 Nm per amp. It draws 13.1 A at rated load. It can handle up to 82 A at peak load. The phase inductance is 13.7 millihenries. This ensures consistent current regulation and smooth torque control. The brake adds 4.2 kg to the total weight. The brake also increases the system inertia by 0.042 × 10⁻³ kg·m².
