Product Description:

The PMB32D-00100-02 brushless servomotor is supplied by Pacific Scientific as part of the PMB Brushless Servomotors series. Designed for closed-loop motion axes in packaging, material handling, and light machining equipment, the unit delivers controlled torque through electronically commutated windings and permanent magnets. Within an automation cell, it functions as the primary electromechanical actuator that converts drive current into precise angular displacement for indexing tables, pick-and-place heads, or coordinated multi-axis stages.

Mechanical, electrical, and feedback characteristics describe how the motor couples to a drive. A mounting face that follows the NEMA Size 34 pattern fixes the housing to standard gearboxes or brackets with no adapter rings. Continuous torque production at lock is supported by a nominal stall current of 5.4 ARMS, so drive sizing must accommodate that current to avoid fold-back during static holding. Power enters the stator through flying leads, allowing direct routing to cabinet terminals and minimizing connector height. Rotor position is returned by a resolver, giving analog sine-cosine feedback that remains tolerant to high temperature and electrical noise. For thermal protection, a PTC thermistor is embedded in the winding, letting the drive interrupt operation if the copper exceeds its calibrated trip point.

The mechanical output end uses a flat shaft, simplifying torque transmission with set-screw or clamp-style couplings while helping prevent slip under bidirectional load. To raise the electromagnetic stack without changing the frame outline, the lamination pack is built to a stack length multiple of 2, providing a longer active core for higher peak torque when needed. Input conductors are terminated on in-line AMP connectors, which allow quick connection without soldering. The current rating discussed earlier corresponds to operation from a 240 Vac bus, which matches common single- or three-phase industrial inverters.
