Product Description:

The S32GNNA-RNVM-00 servo motor is manufactured by Pacific Scientific and belongs to the S Brushless Motors series. It is a 6-pole neodymium-magnet brushless servo motor intended for closed-loop motion axes in packaging, pick-and-place, and general automation equipment. By delivering controlled torque and speed from a compatible drive, the unit converts electrical commands into mechanical rotation that positions loads with repeatable accuracy.

In continuous operation, the motor can supply a torque of 4.0 Nm at stall without overheating, while transient demands can be met with a peak value of 11.3 Nm. A torque constant of 1.3 Nm/ARMS links commanded current to output torque, so the drive must regulate phase current precisely for predictable motion. Copper windings present 6.2 Ω of line-to-line resistance; this influences thermal dissipation and affects voltage requirements at higher loads. The electromagnetic circuit also exhibits an inductance of 18.0 mH, shaping current rise time and requiring the drive to use suitable PWM switching. The motor is supplied without a holding brake, so mechanical locking must be provided externally when power is removed.

Mechanically, the frame follows the NEMA standard and occupies a NEMA 34 flange, allowing direct interchange with common stepper or servo mounts. The assembly weighs 4.9 kg, and a rotor inertia of 0.34 × 10⁻³ kg·m² supports rapid acceleration without excessive overshoot. A voltage constant of 0.82 VRMS/rad/sec indicates the back EMF produced at speed and assists the drive in commutation. Viton sealing on the shaft protects internal bearings from contaminants, and a two-stack magnetic core increases torque density along the short axis. Electrical connections exit through a motor-mounted MS connector, while feedback is delivered by a Size 21 frameless resolver; no secondary feedback device is included. The motor uses a G winding type and is matched to drives that operate on standard industrial bus voltages.
