Product Description:

The R35JEAC-R2-NS-NV-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. It is intended for industrial automation axes that require dependable torque and velocity control. In closed-loop operation, the motor converts drive current into controlled rotary motion so machine tools, pick-and-place modules, and packaging stations can hold position accurately and follow programmed motion profiles. This makes it suitable for equipment that needs repeatable movement and stable response during frequent speed or load changes.

This motor can maintain a continuous shaft load of 3.8 Nm and withstand momentary demand up to 10.1 Nm, providing a useful gap between steady running torque and short peak load requirements. At rated excitation, it turns at 1700 rpm, which suits gear-driven or belt-driven transmissions in many industrial axes. Dynamic response is supported by a rotor inertia of 0.13 × 10^-3 kg·m², which helps limit overshoot when command values change quickly. The motor has a 3.25-inch square frame, so it fits compact machine layouts, and the housing uses Style C for compatibility with matching Pacific Scientific brackets. A medium winding suits common industrial drives, while the frameless size 21 resolver supplies the primary feedback signal for position control. No secondary transducer is installed, and the motor is built without a shaft seal to reduce drag.

An integrated 24 V DC brake holds the shaft when power is removed, which helps prevent load drift on vertical or suspended axes. Torque is produced by rare-earth samarium cobalt magnets, and the laminated core extends for 5 inches to provide the active magnetic length used by the motor. The unit uses English mounting, allowing direct attachment to matching NEMA gearheads and related hardware. These features support compact installation while keeping the motor suitable for mid-range duty in automated machinery.
