Product Description:

The R33HENC-TS-NG-NV-00 by Pacific Scientific belongs to the R Series Servomotors. This servomotor is developed for automation systems and motion control needs. Under different loading scenarios, this model delivers both efficient torque delivery and operational stability. This compact motor maintains a weight between 2.5 to 4.6 kg and suits integration within automation systems.

This R33HENC-TS-NG-NV-00 servomotor provides continuous stall torque variations of 1.6 to 3.6 Nm. It also can produce peak torque ranges between 7.4 to 18.1 Nm. Its continuous stall current ranges between 3.6 and 7.8 A, with peak current capacity from 32 to 71 A. The motor exhibits effective torque output properties derived from 0.49 to 1.12 Nm/A torque constant operation. The motor’s voltage constant spans between 0.49 to 1.12 V/rad/sec. This provides optimal conversion of energy for speed regulation. The R33HENC-TS-NG-NV-00 servomotor exhibits stable electrical characteristics because of its line-to-line resistance. This remains between 7.3 to 9.2 Ohms in cold conditions and 10.9 to 13.9 Ohms during hot conditions. The inductance values of 23 to 42 mH allow operation control through the reduction of the current ripple. The motor exhibits quick control input responsiveness through an inertia value that spans between 0.051 to 0.114 kg·m² × 10⁻³.

Continuous demanding use of the R33HENC-TS-NG-NV-00 servomotor is supported by its thermal capabilities. The object dissipates heat efficiently because of its thermal resistance range between 0.93 to 0.70 °C/W. The thermal time constant of the motor extends from 20 to 29 minutes to sustain temperature stability. Static friction operates at 0.026 - 0.053 Nm strength to decrease energy waste when starting operations. The value of the viscous damping coefficient fluctuates between 0.0045 to 0.012 Nm/Krpm thus minimizing speed change oscillations.
