Product Description:

Pacific Scientific manufactures the PMB22D-10116-00, a unit in the PMB Brushless Servomotors series intended for distributed motion platforms in packaging lines, pick-and-place modules, and semiconductor handling stages. By combining a three-phase stator with rotor-mounted magnets, this motor supplies tightly regulated torque and velocity under servo drive control. Its compact envelope is optimized for axis groups where limited space and fast, repeatable response are more critical than raw horsepower, and it operates through electronic commutation rather than brushes.

The mechanical envelope follows the NEMA Size 23 mounting standard, giving a 2.25-inch square face that mates with common gearheads and linear slides. Under a maximum bus of 240 Vac, the motor carries a nominal stall current of 5.4 ARMS, a value used to check thermal margins during locked-rotor duty. Position feedback is supplied by a 4096 ppr incremental channel from a Digital Encoder with commutation; the commutation tracks let the drive align phase currents without separate Hall sensors. These electrical characteristics support stable servo loops and precise micro-positioning within the encoder resolution during high-bandwidth moves.

Field wiring enters through Flying leads terminated in crimped AMP connectors, reducing cabinet depth because no right-angle plug body is required at the motor. The output end uses a Round shaft, so couplings, timing pulleys, or threaded nuts can be fitted without additional machining. A stack length multiple of 2 means that two lamination sections are used, which increases torque relative to single-stack variants while keeping the same frame height. The motor is supplied as a Standard Motor, so its windings, seals, and finishes follow the standard configuration and remain compatible with off-the-shelf drives in the same voltage class.
