Product Description:

The R32GMNC-R2-NS-VS-00 is a brushless servo motor manufactured by Pacific Scientific and assigned to the R Servomotors series. In motion-control installations, the motor supplies commanded torque and velocity so that positioning tables, indexers, or conveyors follow programmed profiles with minimal error. Its design combines a rare-earth magnetic circuit, metric mounting features, and resolver feedback to link a digital drive to the mechanical load. Because the motor is brushless, commutation is handled electronically by the drive rather than by mechanical brushes, which reduces wear during repeated cycling. The unit is suited for automation axes that require repeatable positioning and stable speed control over long operating periods.

The motor has a continuous stall torque of 1.7 Nm, allowing it to hold or move loads without overheating when cooled by natural convection. Speed commands can reach 4000 rpm, a value matched to the winding back EMF so the drive stays within its DC bus limits. During acceleration, the electromagnetic structure can deliver up to 4.40 Nm, providing short-term reserve torque for overcoming friction or inertia. The rotor inertia is 0.071 × 10⁻³ kg·m², which supports quick starts and stops while placing modest demands on the current loop. This balance of peak torque and inertia helps the axis respond quickly to changes in command speed or load. Mechanical integration is aided by the compact 3.25-inch square frame, and the motor also uses a C housing style aligned with standard flange patterns.

Position data come from a frameless resolver of transmitter type, size 21, allowing the drive to close the loop with high immunity to electrical noise and heat. The motor uses rare earth samarium cobalt magnets, which sustain flux at elevated temperatures and support a compact magnetic stack. Environmental sealing is provided by a Viton shaft seal that resists lubricants and mild chemicals, while metric pilot dimensions help align the motor to mating gearheads or mounting plates. The laminated core has a stack length of 2 inches, which sets the motor's axial length. The motor does not include an integral holding brake.
