Product Description:

The R65HENA-TS-NS-NV-00 is a brushless servo motor manufactured by Pacific Scientific and positioned in the R Servomotors series. Designed for closed-loop motion axes, it supplies controlled torque and speed so actuators, gantries, or indexing tables can reach commanded positions in repetitive cycles across automated equipment. It operates with external drives that regulate stator current according to feedback, delivering predictable shaft rotation without mechanical slip. It is intended for servo applications where precise current control from the drive determines dynamic response and positioning accuracy.

At its rated operating point, the motor can hold a continuous stall torque of 13.6 Nm, providing steady force against static loads before motion begins. When the application demands short bursts of acceleration, it can deliver a peak torque of 33.3 Nm without exceeding thermal limits. Rotor inertia is 1.26 × 10⁻³ kg·m², which balances quick speed changes with damping against oscillation. The magnet set uses rare-earth samarium cobalt, which produces high flux density and helps keep torque stable across the operating range. The winding is optimized for a rated speed of 4300 rpm, allowing high throughput when paired with a matching drive.

The motor has a 5.75 in. square frame and follows an English mounting pattern for compatibility with NEMA-style machine interfaces. Its stack length is 5 inches, creating a compact profile while still accommodating the winding configuration. The winding is classified as High Speed, so its electrical characteristics suit higher drive voltages. Primary rotor position is reported by a Tachsyn transducer, and no secondary feedback element is fitted. The housing is standard, the design does not include a shaft seal, and the motor is supplied without a holding brake, so external sealing or a separate holding method may be needed when contamination control or power-off load retention is required.
