Product Description:

The PMA54Q-10100-00 is a brushless servomotor manufactured by Pacific Scientific as part of the PMA Brushless Motors series. Classified as an AC-powered permanent-magnet actuator, it converts electrical energy into precise shaft rotation for indexing tables, pick-and-place arms, and similar motion-control stations on the factory floor. It is intended for axes that need repeatable rotary motion, stable speed regulation, and compact integration with servo amplifiers. The unit is built without a holding brake, relies on external load-side locking when power is off, and uses a closed keyway shaft so couplings can transfer torque without slippage.

In continuous stall, the motor can deliver 13.5 Nm of torque, which it can sustain indefinitely with rated cooling while the rotor remains locked. During acceleration or transient overloads, it can produce a peak torque of 41.0 Nm, giving additional headroom for rapid starts and short-duration load changes. Supplying this output requires only 7.4 ARMS of winding current at standstill, which helps limit inverter size and cable heating. A rotor inertia of 2.49 × 10⁻³ kg·m² provides moderate resistance to speed changes, balancing responsiveness with stability during speed transitions. The windings are insulated for the 240–480 V AC voltage class, allowing operation on common factory power systems.

The mechanical package weighs 13.0 kg, so the mounting structure must support that static mass as well as the expected dynamic load. A square body measuring 142 mm on each side promotes thermal dissipation and matches standard flange patterns used in servo installations. Power enters through a right-angle connector, and the connector has a right-angle orientation to reduce cabinet depth when cables are routed rearward. Position feedback is supplied by a resolver, which provides rotor angle feedback and tolerates high temperatures and vibration. These dimensions and interfaces suit gearboxes, drive adapters, and motion controllers used with the PMA series.
