Product Description:

The PMB33E-00114-02 is a brushless servomotor produced by Pacific Scientific within the PMB Brushless Servomotors series. Designed for closed-loop motion systems, this motor converts drive current into controlled torque for indexing tables, packaging axes, and other precision automation where fast acceleration and repeatable positioning are required. By integrating a high-resolution feedback device and a compact electromagnetic stack, the unit provides dynamic performance while maintaining the standard mounting envelope used in modular machinery.

The motor ships with flying leads with AMP connectors, allowing direct connection to distributed drives without a mating receptacle and easing cable routing through tight machine frames. Its feedback device supplies 2048 ppr of incremental resolution, giving the controller fine position feedback for smooth velocity control. A NEMA Size 34 frame secures the housing to widely used 3.4-inch square mounts, which helps it fit common machine interfaces. At a maximum supply of 240 VAC, the nominal stall current is 7.4 ARMS, which indicates the current level available at stall within the motor’s thermal limits. A flat shaft end is provided so clamp couplings can be attached without keys, reducing the chance of slip during high-speed cycles.

Thermal protection is integrated through a PTC Thermistor, which changes resistance sharply as the windings approach their maximum temperature and lets the drive initiate a controlled shutdown instead of relying on external sensors. The feedback package is a digital encoder with commutation, delivering both incremental counts and alignment signals so phase current can be oriented immediately at startup. The motor uses a stack length multiple 3, which corresponds to a longer active core within this frame size. The encoder index can be used by the connected drive to confirm position reference during repeated motion cycles.
