Product Description:
The S21GNNA-RNNC-00 Brushless Servo Motor is designed for high performance automation tasks. It delivers precise motion control, smooth operation and long service life. The motor is well suited for demanding environments that require accurate torque and speed control with minimal maintenance and robust sealing.
This S21GNNA-RNNC-00 servo motor has a voltage constant of 19.9 V/kRPM and a line to line resistance of 12.0 Ohms that supports efficient voltage to speed conversion and power handling. Its continuous stall torque is rated at 0.5 Nm that allows stable torque output under prolonged static load conditions. The peak torque capability of the motor reaches 1.36 Nm that enables short bursts of high power when needed. The motor draws up to 4.5 A current to support this peak output. Its line to line inductance is measured at 14.4 mH that aids in current smoothing and noise reduction during operation. The thermal resistance is rated at 2.2 °C/Watt which helps control internal temperature and supports sustained performance under load. The motor features a six pole rotor configuration that enhances magnetic flux and torque production. The high grade neodymium iron boron magnets are used in the rotor to achieve strong magnetic fields and maximize torque density.
The total weight of the Pacific Scientific S21GNNA-RNNC-00 servo motor is 1.4 kg that offers a balance between performance and portability. The integrated long life bearing system minimizes wear and reduces the need for frequent servicing. It ensures consistent rotation over extended periods. The anti cog stator design contributes to smooth motion by reducing torque ripple. This S series servo motor comes equipped with Interconnection connectors that ensures secure and high quality electrical interfaces for reliable communication and control signals during operation.
