Product Description:
The PMA43Q-10100-00 is a brushless servomotor produced by Pacific Scientific within the PMA Brushless Motors series. Designed for fixed-voltage bus systems, it delivers precise rotary motion for pick-and-place arms, conveyor sections, and packaging stations. When coupled to a matching drive and feedback loop, the unit functions as the primary torque source that positions loads quickly and repeatably in automated equipment. Its brushless design also supports accurate speed control during frequent start-and-stop cycles.
At stall, the motor withstands a continuous load of 6.1 Nm, allowing tight speed regulation without overheating when held in position. For dynamic moves, it can generate up to 21.7 Nm, which provides the headroom needed for rapid acceleration profiles. The laminated rotor carries an inertia of 0.52 kg·m² × 10⁻³, balancing fast response with stable low-speed control. The windings draw 7.4 ARMS at the nominal stall point, so conductor sizing can follow standard 75 °C copper tables. The square housing measures 115 mm on each side, which simplifies mounting on metric face plates. This balance of torque, inertia, and frame size suits axes that must hold position accurately and still accelerate smoothly.
Electrical integration is simplified by the right-angle orientation of the 6PP six-pin power connector, which permits low-profile cable routing inside compact cabinets. The windings are in the 240–480 V AC class for use with compatible three-phase drive systems. Position feedback comes from a resolver, providing noise-tolerant analog signals for harsh environments. Because the motor has no internal brake, axes that require holding force must rely on the drive or an external locking device. The closed keyway shaft provides positive torque transmission, and the key is factory fitted to shorten installation time. A mass of 7.6 kg supports thermal stability while keeping the motor light enough for moving-axis assemblies. The configuration is intended for compact servo installations that need dependable feedback and secure shaft coupling.
