Pacific Scientific :: R Series Brushless Servomotors

A broad selection of high performance brushless servomotors.

Choose from five frame sizes, continuous stall torques to 451 lb-in., and some combination of our extensive list of standard options to meet most application requirements for precision motion control.

However you measure performance, PacSci motors have the muscle. From high torque-to-inertia rare earth magnets to flux-focusing ferrite magnetics for matching high inertia loads. From low thermal resistance to maximum power ratings to anti-cog magnet designs for smooth low speed operation. Looking for high peak torque capability to move loads faster? R Series motors can handle high peak currents without demagnetization.

Whatever your control scheme, PacSci brushless servomotors can close the loop - from single resolver feedback to a full selection of primary and secondary feedback transducers. From mounting options to application-specific windings, all in all, PacSci offers JIT delivery on more than 10,000 motor configurations.

Our brushless servomotors are built for long, maintenance-free service life. They may look like other brushless servos, but there's more to these servos than meets the eye: extremely durable long-life bearing systems and rugged TENV, NEMA and IP65 housings for washdown requirements.
