Product Description:
S33GNAA-RNNM-00 is a Sentry S30 series servo motor from Kollmorgen’s Pacific Scientific division. It has a NEMA 34 size frame. Performance features for the motor include a 6-pole design, brushless construction, bearings with a long operating life, compact motor design, integrated thermal protection, and full torque over the complete speed range. Typical applications for the motor include robotics, press feeds, spindles, and machine tools. A resolver functions as the feedback device on the S33GNAA-RNNM-00 motor. There is no secondary feedback device on the motor. A 24 Volts DC holding brake is available on the motor. Protection class of the servo motor is IP65. The main shaft is without a seal. The continuous stall torque of the compact servo motor is 5.1 Nm and the peak torque is 14.8 Nm. Weight of the motor unit is 6.5 kilograms.
The thermal resistance is 0.87 degrees Celsius per Watt. Thermal time constant for the motor unit is 27 minutes. Winding data for the S33GNAA-RNNM-00 motor includes 1.67 Nm/A torque constant, 1.67 V/rad/sec voltage constant, 3.5 Amps continuous stall current, 10.4 Amps current at peak torque, 8.4 Ohms line-line resistance and 25.2 mH line-to-line inductance. The brake’s current rating is 0.72 Amps. Its specified static holding torque is 3.6 Nm. The pull-in time is 10 milliseconds and the drop-out time is 30 milliseconds. The maximum speed specified for the brake is 5000 RPM. The brake increases the motor weight by 1.1 kilograms. The servo motor comes with motor-mounted MS cable connectors. The motor flange measures 3.38 by 3.38 inches, with each mounting hole having a diameter of 0.218 inches. Improper use of the motor voids the warranty and can lead to equipment damage.
