S33GNNA-RNNM-00 Image 1


The S33GNNA-RNNM-00 is a high-performance servo motor in the S Motor Series by Pacific Scientific. This motor stands out for its high torque and low inertia, making it an ideal choice for demanding industrial applications. Its moment of inertia is 0.48 kgm3 x10-3 and it boasts a continuous torque of 5.3 Nm, with a peak torque of 15.3 Nm. The motor's maximum static friction is 0.17 Nm and possesses a viscous damping coefficient of 0.047 Nm/kRPM. Built to last, the S33GNNA-RNNM-00 motor features a thermal time constant of 27 minutes and thermal resistance of 0.870C/A, weighing in at 6.5 kg. With regards to its winding data, the S33GNNA-RNNM-00 motor displays a voltage constant of 0.94 V/kRPM and a torque constant of 1.5 Nm/A, supporting a continuous stall current of 3.5 Amps. The resistance (line to line) measures 5.2 Ohms and inductance (line to line) is 17 mH. Furthermore, the motor's typical rated speed is 1500 RPM when the DC bus voltage is 320 V and the AC is 240 V, delivering a typical rated torque of 4.7 Nm. At a DC bus voltage of 640 V and AC voltage of 480 V, the typical rated torque lowers to 3.6 Nm, while the speed increases to 3900 RPM.

S33GNNA-RNNM-00 by Pacific Scientific is a Brushless Servo Motor in the S Series. The S33GNNA-RNNM-00 features a Frame Size/Stack Length of NEMA 34/3 Stack and a Holding Brake Option of No Brake. This Brushless Servo Motor also has a Size 21 Frameless Resolver for Primary Feedback and a Secondary Feedback of No Secondary. Additional specifications include a NEMA Frame for Shaft & Mounting and a Motor mounted MS Connector for Terminations.
