Product Description:

The R67BEAH-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific and supplied within the R Servomotors series. As a rotary actuator, it converts electrical energy from a matched drive into controlled shaft torque and speed for positioning tasks in automated machinery and material-handling cells. By integrating rare-earth magnets and resolver feedback, the model supports closed-loop motion control in industrial environments. This arrangement allows the drive system to monitor rotor position continuously while maintaining stable response during indexing, holding, and repeated start-stop cycles.

At stall, the motor can deliver a continuous torque of 19.9 Nm, allowing the axis to hold a load without overheating during static positioning. The square frame measuring 5.75 inches square sets the mounting envelope for machine plates and gearbox inputs. Because the flange pattern follows an English bolt layout, the unit fits North American mechanical interfaces. Rotor inertia is specified at 1.72 kg·m² × 10⁻³, which helps balance quick acceleration with stable low-speed regulation. For transient moves, the electromagnetic stack supports a peak torque of 48.9 Nm, so the motor can overcome friction and accelerate loads during short demand spikes without exceeding the drive’s current limits.

A 24 V DC brake is mounted at the rear to mechanically lock the shaft when power is removed, which helps prevent back-driving on vertical axes. Torque production is supported by samarium cobalt rare-earth magnets, which maintain magnetic strength over a wide temperature range and contribute to consistent motor response. Position and velocity are reported through a size 21 frameless resolver of the transmitter type, giving analog sine-cosine signals compatible with many servo amplifiers, and no secondary feedback device is included. The electromagnetic core uses three lamination stacks with a total active length of 7 inches, which supports the continuous rating while keeping the overall motor length manageable in compact equipment layouts.
