Product Description:
The PMB31D-10200-00 is a brushless servo motor manufactured by Pacific Scientific as part of the PMB Brushless Servomotors series. This NEMA-34 frame unit converts electrical energy from matched servo drives into continuous shaft torque for positioning, speed regulation, and cyclic motion tasks in automated machinery. Within industrial automation cells, it acts as the prime mover for pick-and-place axes, indexing tables, or light machining spindles where low maintenance and rapid acceleration are required. Because it uses brushless operation, the motor avoids brush wear and supports stable response during repetitive duty cycles.
The motor uses power and Hall cabling through flying leads with MS connectors, which allows flexible routing while preserving environmental seals. A resolver is embedded for position feedback, providing rotor angle data to the drive during operation. Frame proportions follow NEMA Size 34 standards, so the flange pattern matches common gearboxes and mounting hardware. When operated from a 240 VAC drive, the motor can deliver a continuous stall line current of 5.4 ARMS. The output shaft is round, which allows flexible coupling selection without keyway stress concentrations. This cable and feedback arrangement is useful where the motor is mounted on moving slides or in compact machine layouts.
The design is supplied as a standard motor, so it does not include user-specific windings or special seals. Its magnetic stack uses a stack length multiple of 1, which indicates the shortest lamination length in this frame and helps keep rotor inertia low. The shorter stack supports responsive acceleration in light-duty servo axes and helps the motor react quickly to changing command speeds. It is well suited for applications that favor quick speed changes and moderate continuous torque rather than high-inertia loading.
