Product Description:

The PMB11D-10Y16-10 is a brushless servomotor manufactured by Pacific Scientific and included in the PMB Brushless Servomotors series. It is intended for industrial automation tasks that require closed-loop speed and position control, such as small pick-and-place axes, compact actuators, or indexing tables where accurate and repeatable rotary motion is required. Its compact form makes it suitable for machines that need precise movement without giving up valuable installation space. The motor is built for applications where stable response, predictable torque production, and reliable feedback are important during frequent starts, stops, and direction changes.

The integrated encoder supplies 4096 ppr of resolution, enabling motion controllers to command fine incremental moves with consistent position tracking. A frame designation of Size 17 corresponds to a 1.7-inch square flange that fits space-constrained machinery. When powered from a 240 Vac bus, the windings can sustain a nominal stall current of 5.4 ARMS, providing rated holding torque without exceeding thermal limits. Feedback is delivered by a digital encoder with commutation, so the drive receives incremental position data together with phase information for electronic commutation. The output shaft is a round shaft, which mates directly with set-screw or clamp-style couplings used on timing pulleys and precision gearheads.

A single magnetic stack, shown as a stack length multiple of 1, helps keep rotor inertia low so the motor can accelerate quickly and respond well in short-cycle motion. Common mechanical dimensions across the PMB Brushless Servomotors family allow longer or shorter stack options while keeping the same bolt pattern and pilot diameter. Instantaneous phase reference from the encoder lets a matched drive produce torque immediately after power-up without requiring separate Hall sensors. The description Pacific Scientific identifies the manufacturer, and the designation PMB Series Brushless Servomotor indicates the motor platform used for this model.
