Product Description:

The R63GEBA-R2-NS-NV-00 belongs to the R Servomotors series produced by Pacific Scientific. As a servo motor, it converts electrical energy into precise rotary motion for positioning tasks in automated machinery, packaging equipment, and pick-and-place axes. Its square frame, integrated feedback, and built-in brake allow the unit to be paired directly with matched digital drives, simplifying design and installation in industrial automation cells.

The motor delivers a continuous stall torque of 8.3 Nm, allowing it to hold load torque without overheating when the shaft is locked. During acceleration or rapid indexing, it can reach a peak torque of 20.5 Nm, giving extra headroom for transient loads. The rated speed is 3400 RPM, which balances high throughput with manageable centrifugal forces in the square frame. Rotor inertia is specified at 0.81 × 10⁻³ kg·m², and this low inertial mass permits fast speed changes while still providing adequate damping for control loops. The frame size is 5.75" square, and the English mounting configuration allows the housing to bolt to standard brackets without adapter plates. The standard housing style and winding type support general-purpose thermal limits, and the lack of a shaft seal reduces friction in dry, clean installations.

A 100 V dc brake locks the shaft when power is removed, helping prevent back-drive on vertical axes. The magnetic circuit uses rare earth (samarium cobalt) material, which generates high flux density and improves the torque-to-size ratio. Primary position data comes from a frameless resolver of transmitter type in size 21, and no secondary feedback is fitted, which simplifies cabling. The stack length is 3 inches, which sets the active core depth and contributes to the overall torque constant. The motor uses a standard winding and no shaft seal, making it suitable for enclosed equipment that requires high dynamic response and reliable holding capability.
