PMB31B-20216-02

Product Description:

The PMB31B-20216-02 from Pacific Scientific is a brushless servomotor that fits right into the PMB Brushless Servomotors series. The motor frame follows the well-known NEMA Size 34 standard, making it good for mounting without extra tweaks. For performance, there’s a continuous stall torque marked at 2.1 Nm, which gives steady pulling force when the job involves shifts or pause points across a line. Top speed doesn't lag either, with a rated speed at 2900 rpm to handle fast cycles or steady flows.

Feedback comes standard with multiple options, handy in systems that call for checks or positioning: , , and can fit depending on the setup since the design respects flexibility. The encoder resolution peaks at 4096 ppr, packing in detail for fine steps. System talks go smoother with flying leads with MS connectors, which help wiring when installs run on a deadline. The inside comes prepared for digital output too, with a digital encoder and commutation, making sure precise motor steps match closely with the drive signal. Current at stall is listed at 2.7 ARMS while surges meet a top of 5.3 ARMS for heavier starts—so the numbers hold up under extra load.

Built to work inside industrial automation, this model’s case stands up against bumps or shakes. Speed for projects gets help from the no-load speed at 4300 rpm, speeding up when resistance isn’t an issue. Controls and balancing act stay consistent thanks to inertia held around 0.14 kgm² ×10⁻³, and the inductance rating of 19.6 mH fills out the spec list for those chasing specific tuning curves. The standard torque (1.9 Nm continuous rated, 4.1 Nm peak stall) and power pair up with reliable feedback, so spots needing accurate, stable, and steady turns get backing for a long haul.
