Product Description:

The S24HNNA-RNVC-00 is a brushless servo motor produced by Pacific Scientific as part of the S Brushless Motors series. This 6-pole Neodymium magnet unit is intended for precise velocity and position control on packaging machines, gantry axes, and similar automation stations. Its H winding matches drives that can deliver the required current density, while the four-stack lamination provides a longer magnetic path for additional torque capability. The motor is supplied without a holding brake, uses a Viton shaft seal for oil and dust exclusion, and has no secondary feedback path. Electrical connection is provided through 18-inch flying leads fitted with MS circular connectors.

Under steady thermal conditions, the motor sustains a continuous stall torque of 1.6 Nm, enabling it to hold a load at zero speed without exceeding its temperature limits. For short accelerations, it can deliver a peak torque of 4.94 Nm. The electromagnetic coupling between the windings and the rotor is characterized by a torque constant of 0.3 Nm/ARMS, so each ampere supplied by the drive produces a predictable amount of torque. A line-to-line inductance of 2.2 mH helps filter high-frequency current spikes, while the winding resistance of 1.8 Ω affects copper losses and continuous current capability. The voltage constant is 0.19 VRMS/rad/s, which aligns with typical low-voltage servo amplifiers.

Mechanically, the motor weighs 2.7 kg, which helps keep moving mass low on mobile or top-mounted axes. Its rotor inertia of 1.0 × 10⁻⁴ kg·m² supports rapid speed changes without excessive drive current surges. The front face follows the NEMA frame mounting standard and uses the NEMA 23 pattern, so it fits equipment built for that mounting size. Position feedback is supplied by a Size 21 frameless resolver, providing shaft angle information across the full speed range even in electrically noisy environments.
