Product Description:

The PMB31D-10116-00 is a brushless servomotor produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. It is designed to supply tightly regulated torque and speed in automated assembly lines, pick-and-place gantries, and small conveyor stations where repeatable motion is required. Direct coupling to a driven load lets the unit translate drive current into precise angular displacement, while its feedback loop helps maintain commanded motion under changing mechanical resistance, frequent starts and stops, and the variable duty cycles common in industrial automation.

The frame follows the NEMA Size 34 outline, so mounting holes and shaft center height match standardized gearboxes and linear actuators in that frame class. Continuous stall operation draws up to 5.4 ARMS at 240 VAC, a current level the connected drive must supply without exceeding thermal limits during steady holding duty. Positional data are generated by an internal encoder that delivers 4096 ppr, allowing high-resolution commutation and fine incremental motion during indexing and positioning tasks. Power, hall, and encoder conductors exit as flying leads with AMP connectors, which keeps the connection layout compact and supports straightforward integration into enclosures with limited cable space. Rotor alignment is synchronized through a digital encoder with commutation, so the drive receives the phase information needed for controlled startup and stable low-speed operation.

The motor is issued as a Standard Motor, so no custom winding or flange changes alter its normal electrical characteristics. A round shaft transmits torque to couplings or pulleys without a keyway, which helps reduce localized stress during frequent reversing motion. Within the part code, a stack length multiple of 1 indicates the shortest magnetic core used in this series, favoring low inertia for quick acceleration and deceleration. The overall configuration is identified as a PMB Series Brushless Servomotor, which places the unit within the established PMB motor range for compatible electrical operation and control behavior.
