Product Description:

The PMB33F-00116-00 is a brushless servomotor built by Pacific Scientific and supplied within the PMB Brushless Servomotors series. As a permanent-magnet AC motor intended for closed-loop motion axes, it converts drive current into precise torque while the embedded feedback device reports rotor position to the controller. In packaging lines, pick-and-place gantries, or indexing tables, the unit’s compact electromagnetic assembly helps achieve repeatable positioning and velocity profiles required in industrial automation tasks.

The motor core is scaled to the NEMA Size 34 frame, so its mounting face and shaft height align with standard U.S. flange patterns. At 240 VAC, the stator can accept a peak stall current of 11.0 ARMS, permitting high startup torque without demagnetization. Position feedback is generated by a 4096 ppr optical track, giving the controller 12-bit resolution after quadrature decoding and supporting fine velocity loops. This encoder also supplies electronic commutation signals, and the integrated digital encoder with commutation eliminates separate Hall sensors and reduces wiring. A flat shaft end maximizes coupling area for set-screw hubs and keeps the rotor keyless, which is useful where backlash must be minimized.

For cabinet routing, the stator leads exit as flying leads with AMP connectors, allowing crimp-on mating plugs rather than hardwired terminations and simplifying cable connection. The magnetic package uses a stack length multiple of 3, giving a longer lamination stack than smaller variants and supporting higher continuous torque density. Because the model is supplied as a standard motor, it uses the base winding and mechanical options offered in the PMB family. Its pole count and encoder formatting are matched to the motor’s feedback arrangement so the controller can maintain stable commutation and speed regulation.
