Product Description:

The PMB33C-00114-02 is a brushless servomotor manufactured by Pacific Scientific and supplied within the PMB Brushless Servomotors series. It is intended for integration with compatible digital drives so that precise torque and velocity loops can be maintained in automated assembly stations, packaging machines, and material-handling gantries. By coupling permanent-magnet rotary motion with electronic feedback, the unit provides accurate bidirectional positioning that supports repeatable cycle times and high throughput in industrial automation.

Power and signal conductors emerge as flying leads with AMP connectors, which eliminates a mating receptacle on the housing and allows quick harness termination. Rotor position is reported by a digital encoder with commutation. Its incremental channel has a resolution of 2048 ppr, giving the controller 2048 discrete counts per mechanical revolution for fine incremental moves. The mechanical frame follows the NEMA Size 34 outline, so the mounting holes and pilot diameter match standardized flange dimensions used on many motion stages. Under a maximum 240 VAC bus voltage, the motor develops a nominal stall current of 3.8 ARMS, which the drive must be able to supply continuously when the shaft is locked and energized.

A built-in PTC Thermistor is embedded in the winding to signal the drive if temperature limits are approached, which allows automatic derating. The shaft end uses a flat shaft profile, simplifying rigid coupling to gears or pulleys without a key. Magnetic output is scaled by a stack length multiple of 3, which indicates that three lamination sections are installed to increase continuous torque compared with shorter stacks. The motor is identified as a PMB Series Brushless Servomotor for use with compatible Pacific Scientific controls.
