Product Description:
The PMB22B-10100-00 is a brushless servo motor produced by Pacific Scientific within the PMB Brushless Servomotors series. As a permanent-magnet AC motor, it supplies controlled torque and speed for positioning axes and continuous-duty drives in industrial automation. The motor works with compatible servo drives to convert electrical commands into mechanical rotation for pick-and-place units, conveyors, and similar motion tasks. This arrangement allows the drive system to regulate motion precisely during indexing, speed changes, and steady rotation in compact machine assemblies.
Its frame dimension is NEMA Size 23, a mounting pattern that allows the unit to replace standard stepper or DC motors that use the same flange dimensions. The winding draws a nominal stall current of 2.7 ARMS when operated from a bus up to 240 VAC, indicating the continuous phase current the drive must supply when the rotor is locked at rated temperature. The connector arrangement uses flying leads terminated by AMP connectors, so power and feedback cables can be routed directly to terminal blocks or harnesses without a separate mating plug. This cable style reduces connector bulk at the motor and can simplify routing where enclosure space is limited. The insulation system and winding impedance are selected for continuous-duty operation within that voltage range.
Feedback is furnished by a resolver, giving absolute rotor position over a wide temperature range and providing sinusoidal signals that tolerate electrical noise better than digital encoders. The rotor uses a round shaft, so torque transmission relies on external clamps or set-screw hubs rather than a keyed interface. This shaft style is commonly paired with couplings or pulleys that clamp directly to the shaft surface. A stack length multiple of 2 places the magnetic stack in the mid-range of the series, balancing inertia with torque production for moderate load profiles. The motor is classified as a Standard Motor, which indicates a standard configuration rather than a custom modification.
