Product Description:
The R33GEBC-R2-NS-VS-02 servo motor is produced by Pacific Scientific within the R Servomotors series. As a brushless rotary actuator, it converts drive current from a matched servo amplifier into controlled shaft motion for positioning and speed regulation tasks in automated machinery. The frameless resolver used as the primary feedback device supplies rotor-angle feedback, and no secondary feedback device is fitted, which simplifies cabling. Its inch-based mounting interface fits equipment built to inch-based layouts.
Bearing and winding design allow the motor to deliver a continuous stall torque of 2.5 Nm; this is the steady rotational force available when the rotor is locked, helping the axis hold load without drift. During rapid acceleration, the drive can momentarily rise to a peak of 6.54 Nm, giving extra headroom for overcoming static friction. The electromagnetic structure is wound for a base velocity of 3000 rpm, so commanded speed changes within that limit remain within thermal ratings. Rotor inertia is only 0.093 × 10⁻³ kg·m², letting the servo respond quickly to controller commands with minimal overshoot. A rear-mounted 100 V DC brake clamps the shaft when power is removed, securing vertical or safety-critical loads.
The square front face measures 3.25 inches on each side, giving a compact footprint that fits into tight machinery envelopes while matching the C-style housing used for this model. Rare-earth magnets made from samarium cobalt sustain magnetic flux at elevated temperatures, so dynamic performance remains stable during high-duty cycles. A Viton shaft seal guards the internal bearings against coolant or dust intrusion, extending service life in washdown or particulate environments. The laminated stator stack is built to a length of 3 inches, balancing power density with thermal mass and matching the standard winding set.
