Product Description:

The PMB33C-10100-01 is a brushless servomotor in the PMB Brushless Servomotors series, manufactured by Pacific Scientific. It converts drive current into precise rotary motion for automated handling equipment, light conveyors, and packaging stations, where tight velocity regulation and rapid index moves help keep motion consistent through repeated cycles. Its brushless design supports controlled starts, stops, and speed changes in compact automation systems that need accurate rotary output. The motor is well suited to axes that reverse direction quickly without losing speed stability.

Its frame is built to the NEMA Size 34 standard, so the bolt circle and pilot diameter match common 3.4-inch flange gearboxes. At line voltages up to 240 Vac, the motor draws 3.8 ARMS when held at stall, and the connected drive must be set to handle that current level. The power leads exit the housing as flying leads with AMP connectors, allowing direct connection without a terminal box. Rotor position is returned to the drive by a resolver, providing analog sine-cosine feedback that remains accurate in high-temperature areas. A stack length multiple of 3 means the stator uses a longer active stack for higher continuous torque than shorter stack lengths. The motor also includes a shaft seal, which helps keep fine dust or coolant from reaching the front bearing.

The motor uses a round shaft, which simplifies coupler alignment because there is no keyway to impose a fixed angular position during assembly. That setup avoids the need to align a keyway and leaves the feedback device responsible for reporting rotor position to the drive. The sealed front end helps protect the bearing area in compact machine spaces where splash or fine debris may be present. Analog feedback and a common mounting format also make the motor practical for enclosed equipment with limited installation space.
