R35JEBC-R2-NS-NV-00 by Pacific Scientific

The Pacific Scientific R35JEBC-R2-NS-NV-00 servomotor is a precision brushless actuator from the R Servomotors series by Pacific Scientific. Built for industrial automation applications, this motor provides a continuous stall torque of 32 lb-in and an impressive peak torque of 160 lb-in. Featuring a 117 V/Krpm voltage constant and a continuous stall current of 3.6 A, it excels at delivering accurate, repeatable motion control for tasks such as robotics, indexing tables, and automated assembly equipment.

Under the hood, the R35JEBC-R2-NS-NV-00 offers robust electrical and thermal performance. Its line-to-line resistance measures 9.2 Ohms at cold start and rises to 13.9 Ohms at operating temperature. The motor’s inductance of 42 mH ensures smooth current transitions, while a torque constant of 9.9 lb-in/A (1.12 Nm/A) translates electrical input directly into mechanical torque. Thermal management is handled through a resistance of 0.70 °C/Watt and a thermal time constant of 29 min, allowing for controlled heat dissipation under continuous operation. Static friction is kept to a minimum at 0.47 lb-in, and the viscous damping coefficient of 0.11 lb-in/Krpm reduces oscillations, ensuring stable and responsive performance.

Designed for durability and efficiency, this motor weighs only 10.2 lbs (4.6 kg) and features a low rotor inertia of 0.00101 lb-in·s², optimizing its dynamic response and reducing energy waste. The device draws up to 35 A at peak load yet maintains a modest 3.6 A during continuous operation, balancing power and efficiency. These attributes combine to deliver reliable operation in harsh industrial environments, improving cycle times and reducing maintenance downtime. The R35JEBC-R2-NS-NV-00 meets stringent industrial automation requirements, making it an ideal solution for systems demanding precision, longevity, and consistent torque delivery.
