Product Description:

The PMB33C-00116-02 is a brushless servomotor produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. Designed for industrial automation, the motor delivers closed-loop rotary motion so that packaging stations, small gantries, or material feeders can hold programmed profiles under variable load. Its rare-earth magnet assembly supports rapid acceleration while keeping the housing compact, letting designers fit the unit into multi-axis frames where available space and moving mass must be kept under control.

The motor body follows the NEMA Size 34 mounting pattern, giving it a 3.4-inch square face that mates with standard gearboxes and brackets used on compact automation axes. With a 240 VAC supply, the windings accept a nominal stall current of 3.8 ARMS, which indicates the continuous torque level the drive can apply without excessive heat rise in normal service. Rotor position is sampled by a digital encoder that outputs 4096 ppr, and this feedback resolution supports smooth velocity regulation and accurate position tracking when paired with a suitable drive. The same device supplies electronic commutation cues through a digital encoder with commutation, so no separate Hall sensor package is needed inside the motor housing. Power and feedback exit the stator as flying leads with AMP connectors, which simplifies routing in machines that use short cable runs or compact junction points.

Thermal supervision comes from a PTC Thermistor embedded in the windings, giving the drive a direct signal so current can be reduced before insulation temperature rises too far. A flat shaft simplifies coupling, letting pulleys, hubs, or clamping arms mount directly without a keyed connection. The magnetic circuit uses a stack length multiple of 3, increasing copper volume and torque capacity compared with shorter variants in the same frame. This arrangement suits repeatable indexing and feed applications where steady servo response matters as much as compact motor dimensions.
