Product Description:

The PMA44R-10100-00 is a brushless servomotor manufactured by Pacific Scientific for the PMA Brushless Motors series. As a permanent-magnet rotary actuator, it converts drive current into precise torque so motion axes in packaging machines, pick-and-place stations, and material-handling cells can be positioned repeatably. Its integrated feedback delivers rotor angle to the drive in real time, allowing closed-loop speed and position control that is essential for modern industrial automation.

The motor develops a continuous stall torque of 8.2 Nm, enough to hold static loads without additional gearing, while its peak torque reaches 29.4 Nm to accommodate acceleration spikes. Supplying this output requires a winding current of 11.0 A RMS, and the associated copper loss must be considered when sizing the drive. The coils are designed for a voltage class of 240–480 V AC, making the motor suitable for use with common three-phase servo drive systems. Dynamic response is supported by a rotor inertia of 0.68 kg·m² × 10⁻³, giving a balance between quick acceleration and mechanical damping. A four-stack lamination core increases flux density, and the unit is supplied without a brake so holding force must come from the drive or external hardware.

The motor has a body square of 115 mm, which matches standard IEC mounting flanges and helps dissipate heat generated during rated operation. The assembly weighs 9.0 kg, adding thermal mass while remaining suitable for standard mounting arrangements. Power and feedback wiring exit on the side through a right-angle housing, and the 6PP six-pin power receptacle simplifies connection to shielded motor cables. Position data is supplied by a resolver, which tolerates vibration and high temperatures better than optical devices. A closed-keyway shaft with the key fitted transmits torque directly to couplings or pulleys.
