Product Description:
Pacific Scientific produces the R servomotor R63GENA-NP-RW-VS-02 for automation systems in the field of robotics and packaging machinery. It features class H electrical insulation for thermal endurance up to 155°C, that makes it operatable in continuous long cycles at high speed. This motor is enclosed in 5.75 inches, square frame that is constructed as a TENV design and it follows NEMA mounting configuration.
The R63GENA-NP-RW-VS-02 motor is composed of cobalt permanent magnets to give high torque and quick accelerated features. It has 8 Nm of continuous stall torque when operating and possess the ability to produce a maximum of 26 Nm peak torque. This motor has a rated torque constant of 0.66 Nm/A and the voltage constant is at 70/Krpm. It functions on a constant 13.5 A current and achieves its optimal peak performance by utilizing 82 A of maximum current. The R63GENA motor has a cold line-to-line resistance of 0.93 Ohms while its hot impedance measures up to 1.4 Ohms for continuous usage. It offers line inductance of 8.9 mH and the value of static friction is bound to 0.16 Nm, along with a viscous damping coefficient of 0.046 Nm/Krpm. The R63GENA motor’s thermal resistance is 0.51 °C/W and it takes 19 minutes to attain ambient thermal state by dissipating heat through its aluminum heatsink of dimensions 18” x 18” x 1/2”.
The R63GENA-NP-RW-VS-02 motor comes with a rotational inertia of value 0.00079 kg·m² and it is accompanied by a Viton sealed shaft to achieve the IP65 protection class from dust and water. It has internal thermistors for over temperature protection and this servomotor lacks a feedback device from the pre-factory assembly but an external encoder can be fitted to monitor speed and position.
Frequently Asked Questions about R63GENA-NP-RW-VS-02:
Q: Why does the R63GENA-NP-RW-VS-02 use Class H insulation?
A: Class H insulation allows the motor to handle temperatures up to 155°C, enabling it to run long cycles at high speed without thermal failure.
