Product Description:
The PMB33E-00216-02 is a brushless servomotor introduced by Pacific Scientific as part of the PMB Brushless Servomotors series. It is intended for closed-loop positioning and velocity control in automated machinery, where rapid torque changes and repeatable motion profiles are required for pick-and-place heads, indexing tables, or light gantry axes. Its brushless design supports accurate starts, stops, and speed changes while reducing the maintenance associated with brushed motor assemblies. That operating profile suits packaging, assembly, and light material-handling equipment that depends on consistent servo response over repeated duty cycles.
This model uses a frame that matches the NEMA Size 34 mounting pattern, so it can fit many machine layouts that already accept that standard motor size. A nominal stall current of 7.4 ARMS at 240 VAC is the continuous current the drive must supply while the rotor is locked. Rotor position is reported through an incremental encoder that delivers 4096 ppr, which supports fine velocity loops and tight position tolerances. The sensing element is a digital encoder with commutation, furnishing both incremental feedback and Hall signals so the drive can align phase currents immediately after power-up. Electrical termination is provided on flying leads with MS connectors, which allows direct connection without a separate terminal box.
Mechanical coupling is handled by a flat shaft, giving a positive grip for set-screw hubs while avoiding keyway stress concentrations. Thermal protection is embedded through a PTC thermistor; its steep resistance rise alerts the controller when winding temperature approaches the limit. The electromagnetic stack uses length multiple 3, which increases torque output compared with shorter stacks in the same frame diameter. This arrangement supports compact axis assemblies that need stable feedback and temperature monitoring during frequent acceleration and dwell cycles. The motor is well suited to repeatable high-cycle motion systems built around Pacific Scientific components.
