Product Description:
The PMA43Q-00100-00 is a brushless servo motor built by Pacific Scientific and assigned to the PMA Brushless Motors series. It is intended for closed-loop positioning and velocity tasks in automated machinery where its resolver feedback and smooth shaft allow direct coupling to precision gearheads or belt drives. The motor uses a square frame that fits standard IEC-sized mounting patterns used on packaging lines, pick-and-place gantries, and similar motion stages.
During continuous operation, the motor can deliver 6.1 Nm of stall torque without overheating, providing a steady torque reference for load calculations. For short acceleration bursts, it withstands a peak of 21.7 Nm, supplying the extra torque needed to overcome system inertia and friction. The moving assembly itself contributes only 0.52 × 10⁻³ kg·m² of rotor inertia, so commanded speed changes are achieved quickly while minimizing overshoot. From the electrical side, the stator windings draw 7.4 ARMS at rated stall, and they are wound for a class suitable for inverters that output between 240–480 V AC. These electrical and mechanical limits affect current-loop tuning, velocity bandwidth, and amplifier sizing for the axis controller.
The housing mass of 7.6 kg aids heat dissipation and damps vibration, helping maintain acceptable temperature rise during operation. A frame dimension of 115 mm on each side keeps the center of gravity close to the mounting face, which is useful when the stack length of 3 calls for overhung loads or cantilevered fixtures. Cabling exits through a right-angle conduit box that carries a separate 6PP (6-pin power) connector; this geometry lets wiring stay within machine raceways while maintaining bend-radius limits. The motor has no integral brake or special design add-ons.
