Product Description:

The R63HMBA-R2-NS-NV-00 servo motor is manufactured by Pacific Scientific as part of the R Servomotors series. It is intended for precision industrial automation where repeatable torque and rapid speed changes are required. The unit converts electrical energy from a matched drive into controlled rotary motion and returns resolver-based position data so the motion controller can close the loop on speed, position, and acceleration. This supports axes that must start, stop, and reverse direction with consistent motion control during production.

Under continuous stall conditions, the rotor can deliver 8.3 Nm of torque without exceeding its thermal limits, supplying steady force for tensioning or holding duties. The mechanical design permits operation up to 6000 rpm, allowing direct coupling to compact gearheads or lead screws in high-speed applications. Dynamic response is influenced by a reflected inertia of 0.81 kg·m² × 10⁻³, which supports fast acceleration during repeated positioning moves. Physical integration is simplified by a 5.75-inch square frame that matches common mounting patterns and fits many machine layouts. The stator uses a high-speed winding, which reduces inductance so the drive can supply high-frequency current pulses without voltage saturation.

For transient moves such as indexing or camming, the motor reaches a peak output of 20.5 Nm, providing short-term headroom for overcoming static friction or inertia peaks. A factory-installed electromagnetic brake rated for 100 V DC engages when power is removed, preventing back-driving on vertical axes. The rotor contains rare-earth samarium cobalt magnets that maintain field strength at elevated temperatures. Axial length is limited to 3 inches, enabling installation in confined machine frames. The motor uses metric mounting threads and a size-21 frameless resolver for primary feedback. It has no secondary transducer, and the shaft is open and does not use a seal.
