Product Description:

The PMA54Q-00100-00 is a brushless servomotor produced by Pacific Scientific within the PMA Brushless Motors series. This frame-size 142 mm unit converts electrical power into controlled rotary motion for positioning tasks in automated machinery and material-handling axes. When paired with a compatible drive, it delivers closed-loop performance in pick-and-place stations, packaging lines, and coordinated gantry systems. The absence of an internal brake allows continuous operation without residual holding friction, while the smooth shaft simplifies coupling to gearboxes or direct-drive loads.

The motor sustains a continuous stall torque of 13.5 Nm, giving a steady torque level at zero speed without overheating. During fast indexing or shock loads, it can reach a peak output of 41.0 Nm, which covers short acceleration transients. Rotor inertia is 2.49 kgm² × 10⁻³, which helps moderate speed changes so the servo loop can settle quickly without overshoot. The phase windings draw 7.4 ARMS at nominal stall and are wound for a 240–480 V AC supply, allowing connection to standard industrial drives. A six-pin 6PP power connector routes the three phases and protective earth, and stack length code 4 identifies the fourth lamination segment in this motor design.

The housing forms a 142 mm square, aligning with metric mounting flanges and providing ample surface for conduction cooling. Total mass is 13.0 kg, a value that affects inertia matching when the motor is mounted on moving carriages. Power and feedback cables exit through a right-angle connector set, permitting low-profile routing along machine frames. Position feedback is generated by a resolver, supporting reliable signal integrity in noisy environments and compatibility with analog-tracking servo amplifiers. The motor uses the standard PMA design without special mechanical options.
