Product Description:
Pacific Scientific is known for engineering precision motion control solutions with reliable performance across demanding automation environments. The R Servomotors series including the R33GSNC-HS-NS-NV-03 is developed for accurate torque and speed control applications. It offers a peak torque output of 11 Nm which makes it ideal for systems that require high dynamic response.
The R33GSNC-HS-NS-NV-03 servo motor integrates a rare earth magnet system using samarium-cobalt material for magnetic stability. Its inductance is specified at 22 mH, which helps in noise suppression and current regulation. This servomotor features a brushless design that ensures consistent operation and extended service life. The continuous stall torque is rated at 2.4 Nm, supporting sustained load operations without overheating. A voltage constant of 0.67 V/rad/sec contributes to reliable velocity control. Its low rotor inertia of 0.000072 kg·m² allows for rapid acceleration and precise positioning. The R33GSNC-HS-NS-NV-03 servo motor operates on a supply voltage of 24 VDC and draws a current of 0.21 A during standard load cycles. It has a resistance value of 6.9 ohms ensures stable current flow across the winding. The unit has a thermal time constant of 23 minutes to maintain temperature stability during operation. Its static friction is rated at 0.035 Nm, supporting smooth start-up without excessive mechanical drag. The viscous damping coefficient is 0.0068 Nm/Krpm, allowing controlled velocity damping under variable speeds. The design includes anti-cogging properties for smoother low-speed motion. Protection class is IP65, which makes it suitable for dusty or wet industrial environments. It lacks both shaft sealing and a holding brake reducing mechanical resistance and simplifying the build. Primary feedback is managed using Hall sensors, ensuring dependable rotor position tracking without a secondary feedback device.
The R33GSNC-HS-NS-NV-03 servo motor has a net weight of 3.2 kg, enabling easy integration into compact systems. The unit is rated with low thermal resistance, improving heat dissipation efficiency under continuous cycles.
