Product Description:
The PMB33F-10200-01 is a brushless servomotor manufactured by Pacific Scientific and placed in the PMB Brushless Servomotors series. Designed for closed-loop motion control, it works with a matched amplifier to generate commanded shaft torque and speed in material handling stations, packaging lines, and light machine tools. Its permanent-magnet rotor eliminates brush wear and supports continuous duty cycles. Resolver feedback returns rotor position to the drive for precise commutation and position regulation during load changes and elevated ambient temperatures. That arrangement also supports stable low-speed control and repeatable positioning.
Mechanical compatibility comes from the NEMA Size 34 frame, which gives the motor a 3.40-inch square mounting face shared with many common stepper and servo packages. Continuous stall capability is limited by thermal rise rather than current, and the nominal stall current at 240 V AC is 11.0 ARMS, so the drive must be able to supply that value without exceeding its protection limits. Power and feedback leads exit as flying leads with MS connectors, which supports connection to harnesses that already use MIL-style circular hardware. For commutation and position feedback, the motor uses a resolver that provides analog sine-cosine signals with good resistance to shock, vibration, and electrical noise. The stack length is a multiple of 3, which increases available torque without changing the bolt circle dimensions.
A shaft seal is fitted at the front endbell to help keep coolant spray or oil mist away from the internal bearings. Torque is transmitted through a round shaft, which makes the motor compatible with clamp-style couplings and timing pulleys that do not require a keyed interface. This layout supports clean mechanical integration in compact servo axes, and it also helps simplify alignment when the motor is installed in tightly spaced equipment. The plain output geometry allows the coupling hub to clamp evenly around the shaft surface during assembly.
