PMB31B-00214-03

Product Description:

The PMB31B-00214-03 servomotor comes from the PMB Brushless Servomotors series under Pacific Scientific. This model carries a NEMA Size 34 frame, putting it in that medium-size class that works for all sorts of machinery lines and automation gear. At its core is a continuous stall torque of 0.40 Nm, and the peak torque can stretch all the way to 1.20 Nm when things get demanding for short bursts. With its regular speed rated at 3,500 RPM, this motor pushes applications through with sound consistency, which fits well for conveyor stations or pick-and-place gear needing stable output.

The housing comes with flying leads paired to MS connectors, a familiar setup where connections just need to be strong without fiddly wiring. A typical weight of 2.1 kg adds up—not too heavy, yet not flimsy, so the install goes on most powered devices without changing brackets. Sizing is kept universal by sticking to NEMA 34 flange mounting, and that base means less hassle during swap-outs and repairs for bigger plants with lots of similar motors. Tracking movements lands smooth from the integrated digital encoder, with a 2048 ppr resolution helping dial in exact positions as the job cycles, which is valuable for robots, feeders, and alignment tasks.

Stack height sits at <1>, typical of this line and simple for spares stocking. Drive health tracks with a 2.7 ARMS nominal stall current at 240 VAC and a windings spec calling for 2.7 A, putting the performance right in line with a lot of existing system wiring. A voltage constant of 0.22 VRMS/rad/sec rounds out what engineers check for matching drives. Rotor inertia measures 0.044 kg·m² × 10¯³, so sudden direction changes don't overshoot by much. Rugged enough for all-day pace, reliable with feedback in tough settings, and flexible during setups.
