Product Description:

The PMB33C-00101-02 is a brushless servo motor produced by Pacific Scientific and supplied within the PMB Brushless Servomotors series. It is engineered for closed-loop motion in packaging lines, pick-and-place heads, and medium-torque indexers where repeated acceleration and deceleration are required. When combined with a compatible drive, the unit converts three-phase electrical power into controlled shaft rotation so mechanical loads can be positioned quickly and with repeatable accuracy in industrial automation cells. This operating role makes it suitable for axes that need short move times, steady servo response, and consistent stopping behavior during repeated production cycles.

The motor uses a NEMA Size 34 frame, which gives the housing a standard 3.4-inch square flange that fits common gearboxes and direct-drive fixtures. Under maximum 240 VAC excitation, the winding can sustain a nominal stall current of 3.8 ARMS, allowing continuous torque production without excessive heating during normal operation. Power, thermistor, and Hall leads exit the stator as flying leads with AMP connectors, which avoids a fixed plug arrangement and allows flexible cable routing. Rotor position feedback comes from an integrated Hall sensor, enabling six-step commutation and initial rotor alignment for the drive. For mechanical coupling, the shaft has a flat, so torque can be transferred with a set-screw hub rather than a keyed interface. These features support straightforward integration in motion systems that use compact motor mounts and standard electrical connections.

A winding-embedded PTC thermistor is provided so the drive can reduce current if the coil temperature rises above a safe limit. The lamination pack uses stack length code 3, which increases magnetic volume and supports higher torque while preserving the standard mounting pattern. The model is a brushless servomotor, and its combination of thermal sensing, rotor feedback, and flying-lead termination supports stable operation across varying loads and duty cycles. This arrangement also allows the connected drive to monitor motor state during operation without requiring unusual feedback or protection hardware.
