Product Description:

The PMB33C-10116-01 is a permanent-magnet brushless servomotor built by Pacific Scientific. This NEMA-frame actuator delivers closed-loop motion when paired with a compatible drive, supplying precise torque and velocity regulation for automated conveyors, small gantries, and material-handling tools on factory floors. Electrical commutation is handled through its integrated encoder so the drive can synthesize phase currents in real time. By maintaining accurate rotor position feedback, the motor supports responsive control loops that improve throughput and repeatability in multi-axis systems.

Mechanically, the motor follows the NEMA Size 34 flange pattern, allowing it to replace stepper or DC units that share the same bolt circle without bracket changes. The electromagnetic circuit is rated for a nominal stall current of 3.8 ARMS, so the selected drive must deliver this value continuously at 240 VAC while staying within thermal limits. Position data come from an optical encoder that yields 4096 ppr, and those pulses, together with three commutation tracks, provide feedback through the integrated digital encoder with commutation package. For field wiring, the stator windings and feedback leads exit the housing as flying leads with AMP connectors, which simplifies termination when the motor is mounted inside tight enclosures.

A factory-installed shaft seal surrounds the output journal to restrict lubricant loss and block airborne particles from entering the front bearing. The output journal is round, making it compatible with set-screw or clamp-style couplings commonly used on gearboxes and lead screws. Internally, the stator uses a lamination stack length multiple of 3, which increases magnetic volume without extending the frame diameter. The motor belongs to the PMB Brushless Servomotors series and is suited to medium-inertia, high-resolution servo axes.
