Product Description:

The S32GMNA-RNNE-00 is a 6-pole neodymium magnet brushless servo motor produced by Pacific Scientific within the S Brushless Motors series. As a rotary actuator, it converts controlled electrical input into precise shaft motion for positioning and velocity loops used in pick-and-place modules, indexing tables, and other servo-controlled axes in automated machinery. The brushless design supports smooth commutation and repeatable low-speed control when paired with a compatible servo drive. Primary position feedback is supplied by a size 21 frameless resolver, and a secondary feedback channel is not included.

Its continuous stall capability is rated at 4.0 Nm, which is the torque the motor can deliver continuously, while the short-term ceiling rises to 11.3 Nm for acceleration or brief shock loads. A torque constant of 1.3 Nm/ARMS links commanded current from the drive to shaft output and helps relate current demand to produced torque. Electrical characteristics include a line-to-line resistance of 6.2 ohms and a phase inductance of 18.0 mH, which affect copper loss, current rise, and inverter ripple filtering. The motor has no holding brake, so static load retention must be provided by external mechanics or drive-produced torque. It uses the G winding code for this two-stack version, connects through Interconnectron connectors, follows a metric mounting pattern, and comes without a shaft seal or internal brake.

The motor uses the NEMA 34 footprint common to mid-range servo stages, and its housing mass is 4.9 kg. That package size fits machine layouts that use this common mounting footprint without requiring a larger motor envelope. Dynamic response is supported by a rotor inertia of 0.34 × 10⁻³ kg·m², which helps the drive achieve fast loop response without excessive overshoot. The back-EMF coefficient of 0.82 VRMS/rad/sec helps estimate regeneration voltage during rapid deceleration and supports DC bus selection. Because the motor is supplied without a shaft seal, it is best suited for clean or protected enclosures where the surrounding machine structure provides the needed protection.
