Product Description:

The PMB33C-00216-00 is a brushless servomotor produced by Pacific Scientific and assigned to the PMB Brushless Servomotors series. As a permanent-magnet motor for closed-loop positioning and velocity control, it converts drive current into regulated torque for pick-and-place modules, conveyors, and similar axes in automated machinery. Its rotor and stator are aligned at the factory with the integrated feedback device, so the drive amplifier can command small incremental moves with stable commutation and predictable response during repeated cycling. This layout supports repeatable motion in machines that need precise starts, stops, and speed changes across short operating cycles.

Electrical and feedback connections are supplied as flying leads with MS connectors, allowing direct loom integration while maintaining sealing at the mating plugs. Rotor position is reported by an incremental encoder that outputs 4096 ppr, giving fine per-revolution resolution for velocity regulation and commutation. The housing footprint matches NEMA Size 34, so it fits mounting plates that use this common frame standard. At continuous stall with 240 VAC input, the winding draws 3.8 ARMS, which suits mid-power servo amplifiers on compact axes. Position feedback and commutation are both handled by a digital encoder with commutation, so a separate Hall sensor assembly is not required.

Mechanical interfacing is simplified by a flat shaft end, which can be used with rigid couplings or timing pulleys. The shaft form also keeps the output interface simple where keyed transmission is not required. The magnetic stack uses a stack-length multiple of 3, increasing active length over shorter versions while keeping the motor within the same general frame class. This build is classified as a Standard Motor, so it uses the normal production configuration rather than a special winding or seal package. The unit combines a permanent-magnet rotor with high-resolution feedback, which supports smooth low-speed motion and accurate positioning on coordinated multi-axis equipment.
