Product Description:

The S32HNNA-HGVM-00 brushless servo motor is produced by Pacific Scientific within the S Brushless Motors series. As a 6-pole neodymium magnet unit, it converts drive current from a matched amplifier into rotary motion for positioning axes and continuous-duty process lines such as indexing tables, feeders, and synchronized material handling equipment. The motor follows the NEMA frame mounting convention and is supplied without a holding brake, so applications must rely on external locking or drive torque for power-off stability on vertical or suspended loads. Primary commutation signals are generated by integrated Hall sensors, and a 1024 PPR encoder with a line-driver output provides higher-resolution feedback for closed-loop speed regulation and repeatable positioning.

A continuous stall capacity of 4.0 Nm indicates the torque that can be maintained without overheating, while a peak value of 11.3 Nm supports short acceleration bursts during indexing moves or rapid starts under load. The torque constant of 0.7 Nm/ARMS shows the relationship between phase current and produced torque, which helps the amplifier match commanded current to motor output with predictable response. Electrical behavior includes an inductance of 4.5 mH and a phase-to-phase resistance of 1.6 Ohms. These values affect current rise time, heat generation, and how quickly the motor reacts to changing demand, especially when the axis alternates between steady holding and frequent acceleration.

The rotor has an inertia of 0.34 kg·m² × 10⁻³, which supports brisk speed changes in compact servo axes that need quick starts and stops without excessive overshoot. Total mass is 4.9 kg, helping stabilize the assembly when the motor is mounted to rigid machine structures and reducing the tendency toward unwanted vibration. The housing matches the NEMA 34 frame envelope, allowing installation on equipment designed for that mounting size and bolt pattern without requiring nonstandard adapters. A voltage constant of 0.44 VRMS/rad/sec relates back EMF to speed, and the motor also uses a Viton shaft seal, a motor-mounted MS connector, H-style windings, and two-stack lamination to support reliable mechanical and electrical integration.
