Product Description:

The PMB33F-00114-01 is a brushless servomotor produced by Pacific Scientific for precise rotary motion in automated equipment. It converts drive commands into controlled shaft movement so conveyors, gantry axes, and pick-and-place systems can maintain accurate position and steady speed through repeated duty cycles. By combining permanent-magnet excitation with electronic commutation, the motor delivers responsive torque output for tightly synchronized motion loops. Its overall design is suited to applications that need repeatable motion without the brush wear associated with conventional DC motors.

The housing follows NEMA Size 34 dimensions, which allows installation on standardized mounting patterns used for many machine plates and gearboxes. A nominal stall current of 11.0 ARMS at 240 VAC states the current level the drive must supply to hold torque at standstill without excessive heating. Power and feedback use flying leads with AMP connectors, which provide a direct cable connection without a terminal box. Rotor position is measured by a digital encoder with commutation, and the feedback device provides 2048 ppr for fine low-speed control and accurate velocity regulation. The encoder also supplies the phase alignment information needed by the drive for proper motor commutation during operation.

The motor uses a flat shaft so a coupling can clamp onto the machined surface and resist slip during reversing torque. It can also be ordered with a shaft seal to help limit coolant or airborne contamination at the front endbell. The magnetic stack height follows a multiple of 3, which increases continuous torque while keeping the same mounting footprint. The unit is listed in the PMB Brushless Servomotors series, indicating that it belongs to Pacific Scientific's PMB motor line. This layout supports use on legacy axes where the available installation space is fixed but higher continuous output may be required.
