Product Description:

The PMB33C-00114-03 is a brushless servomotor manufactured by Pacific Scientific within the PMB Brushless Servomotors series. In automated pick-and-place stations, indexing tables, or light machining cells, this motor provides closed-loop torque and velocity so that a drive controller can position a load with repeatable accuracy. Its brushless design also reduces wear associated with mechanical commutation, which helps support consistent motion in equipment that runs through frequent start-and-stop cycles.

The motor is supplied with flying leads with AMP connectors, allowing quick termination where pluggable receptacles are not required. A frame diameter corresponding to NEMA Size 34 fits common U-frame mounts and eliminates adapter plates in legacy machinery. Inside the housing, a digital feedback package delivers 2048 ppr of incremental resolution, which lets a drive resolve motion down to fractions of a degree. The feedback element also produces commutation signals through a digital encoder with commutation, so phase switching stays synchronized to rotor position. When line voltage reaches 240 VAC, the windings can hold a static electromagnetic load of 3.8 ARMS before thermal limits are reached. This combination suits mid-power drive systems that regulate current while maintaining stable low-speed response and repeatable positioning behavior.

A flat shaft end allows rigid set-screw coupling without a keyway, which helps reduce axial stack-up at the driven interface. The lamination height uses a stack code of 3, increasing magnetic flux and peak torque compared with shorter versions in the same frame size. A factory-installed shaft seal and PTC thermistor help protect the motor from splash exposure and provide temperature data for drive shutdown logic. The unit is identified as a PMB Series Brushless Servomotor, which places it within the matching product family for compatible motion-control applications.
