Product Description:

The PMB32D-00100-01 is a brushless servomotor produced by Pacific Scientific and supplied in the PMB Brushless Servomotors series. It works as a direct-drive rotary actuator that converts electrical input into controlled torque and angular velocity for packaging cells, pick-and-place heads, and indexing tables. Because commutation is electronic rather than brush-based, the motor avoids brush wear and supports repetitive start-stop motion in continuous industrial automation duty. It is suited to axes that must reverse quickly and hold commanded speed without the brush maintenance associated with older servo designs.

The power conductors exit as flying leads with AMP connectors, so installation requires a mating plug rather than direct hardwiring. The motor uses NEMA Size 34 dimensions with a 3.38-inch square face, which matches common servo mounts and gearheads. Under locked-rotor conditions on a 240 VAC bus, the winding draws 5.4 ARMS. Position feedback comes from a resolver, which tolerates electrical noise and elevated temperatures while supplying rotor angle data to the controller. Motion is transmitted through a flat shaft end, allowing pulleys or couplings to clamp without a keyway and helping reduce backlash in repeated reversals.

The motor can be ordered with a shaft seal to limit lubricant loss or contaminant ingress when the output flange is exposed to washdown or dust. It uses a stack length multiple of 2, which increases magnetic stack length and raises continuous torque without changing the frame size. This added active material gives the motor more thermal and magnetic capacity than the base length while preserving the same mounting format. Because the outer dimensions stay the same, the motor can fit installations where mounting clearance is fixed but a higher continuous torque level is needed.
