Product Description:

The S32ANNH-RNNM-00 is a brushless servo motor manufactured by Pacific Scientific as part of the S Brushless Motors series. Built with six Neodymium magnet poles, the unit provides closed-loop motion in automated pick-and-place stations, metering equipment, and indexing axes. It is intended for applications that require precise speed and position control during repeated starts, stops, and position changes. That operating profile suits axes that need smooth commutation and repeatable response over frequent motion cycles.

Mechanical output begins with a continuous stall torque of 4.0 Nm, giving the axis enough holding torque at zero speed. Acceleration reserves are supplied by a peak torque of 11.3 Nm, so short bursts of load do not force the drive into current limit. Dynamic response is supported by a rotor inertia of 0.34 kgm² × 10⁻³, allowing the servo loop to command rapid speed changes with low lag. The housing follows the NEMA 34 frame size, which simplifies alignment with standard U.S. gearheads and motor plates. Internally, the type A windings use high-voltage construction, matching drives that supply higher bus voltage and lower phase current.

The motor weighs 4.9 kg, which adds mass for stable mounting without making the unit difficult to handle. Primary position feedback is provided by a Size 21 frameless resolver, and no secondary feedback device is installed. Power and signal leads exit through a motor-mounted MS connector, which keeps terminations on the motor body rather than in a separate junction box. This arrangement supports straightforward cable routing when the lead set must leave the motor directly toward the cabinet or a moving axis. The laminated core uses a 2-stack length to balance torque density with thermal mass during operation. The motor has no holding brake and no shaft seal, so the machine must provide external load holding and protection against contaminant entry. The voltage constant is not specified.
