Product Description:

The PMB32D-00114-01 brushless servomotor is built by Pacific Scientific as part of the PMB Brushless Servomotors series. It operates as a torque-generating element in closed-loop automation axes, converting drive current into rotary motion for packaging machines, material-handling stages, and general positioning tasks. By combining a permanent-magnet rotor with electronic commutation, the motor delivers repeatable speed and position control while maintaining compact dimensions for embedded equipment.

The motor conforms to the NEMA Size 34 frame standard, so its 3.4-inch square flange can be mounted on brackets drilled for motors in the same category. Under a 240 VAC bus, the winding sustains a nominal stall draw of 5.4 ARMS, and matching this current with the amplifier’s continuous rating helps prevent thermal saturation during static holding duties. Rotor position is monitored by a feedback element that supplies 2048 ppr of incremental resolution, giving the controller enough counts per revolution to support fine velocity loops. The integrated digital encoder with commutation also presents three Hall signals so drive electronics can align phase currents immediately after power-up. Power, feedback, and protective earth leave the housing through flying leads with AMP connectors, allowing direct termination to cabinet wiring harnesses without on-motor receptacles.

For environments that expose rotating interfaces to spray or dust, the optional shaft seal limits ingress into the front bearing cavity and extends service life. The output member features a flat along its length, enabling set-screw couplings to clamp positively and eliminate keyways in low-profile assemblies. A lamination pack with a stack length multiplier of 2 increases the active iron volume, which raises continuous torque without changing the external frame.
