Product Description:

The PMB32D-00100-00 is a brushless servomotor produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. The unit is intended for industrial automation axes that require efficient torque production, fast acceleration, and repeatable positioning. Coupled to a compatible digital drive, it delivers closed-loop operation using resolver feedback, allowing machine tools, pick-and-place gantries, and packaging equipment to synchronize motion with controller commands.

The motor frame conforms to NEMA Size 34, a mounting standard that sets the 3.4-inch square face dimension so the housing aligns with off-the-shelf gearheads or clamp brackets. During locked-rotor testing at the maximum rated bus of 240 VAC, it draws 5.4 ARMS of stall current; drive sizing must accommodate this continuous phase demand to prevent current-limit faults when the load resists motion. Power, phase, and resolver leads exit the stator as flying leads with AMP connectors, eliminating detachable plugs and permitting direct routing through machine conduits. Rotor position is measured by a resolver, which supplies absolute analog signals for commutation even under electrical noise. A flat shaft end simplifies coupling to pulley hubs because set screws seat against the machined surface without relying on keyways.

Because it is supplied as a Standard Motor, the unit uses a standard set of dimensions and winding constants rather than a custom configuration. The electromagnetic section uses a stack length multiple of 2, which increases the active iron volume compared with the base length and provides additional torque for high-inertia loads. The longer lamination stack supports stronger torque production without changing the external frame size. That combination helps the motor handle repeated starts, short indexing moves, and similar cyclic motion without requiring a larger housing. This stack option can be matched to the motor current rating to balance acceleration and thermal rise during axis operation.
