Product Description:

Pacific Scientific manufactures the PMB33C-20101-00 servo motor as a member of the PMB Brushless Servomotors series. The unit turns drive commands into controlled mechanical power for automated packaging lines, pick-and-place modules, and compact conveyor sections. By using permanent magnets and electronic commutation, it eliminates brush wear while delivering repeatable torque and speed profiles that match the feedback bandwidth of mid-frame motion axes. The motor’s frame supports direct coupling to driven loads, which can reduce the need for additional mechanical reduction components in compact axis layouts.

The product is a brushless servomotor, so current switching is handled by the drive electronics rather than by mechanical brushes. Its frame follows the NEMA Size 34 envelope, so mounting holes and pilot dimensions align with standard 3.4-inch square flange hardware used on small positioning tables. Under maximum mains conditions, the motor can hold its shaft stationary at 3.8 ARMS stall current while the system voltage remains at 240 Vac. Rotor position feedback is provided by a Hall sensor, which supports six-step commutation in compatible drives. Power and signal conductors exit the housing as flying leads with AMP connectors, allowing straightforward integration where prewired terminations are preferred.

Mechanical output is transferred through a square key shaft, which supports positive torque transmission into couplings or pulleys without relying only on clamp friction. The magnetic length follows a stack length multiple of 3, increasing active material length and raising continuous torque compared with shorter versions in the same frame. Because the motor is supplied as a standard motor, the configuration remains consistent with the base version of this model. This format is useful where the same motor style is installed across multiple compact axes. The housing and electrical arrangement are suited to general motion-control applications that need stable commutation feedback and a straightforward connection layout.
