Product Description:
The PMA54R-10100-00 is a brushless servomotor produced by Pacific Scientific as part of the PMA Brushless Motors series. In automated machinery, this motor delivers controlled rotary motion under closed-loop drive control, supporting positioning, speed regulation, and coordinated multi-axis tasks. The resolver feedback lets the drive track rotor position accurately, and the absence of an internal brake reduces overall length when holding torque is supplied electrically. That feedback also supports stable commutation and helps the controller correct for changing load conditions during motion. These traits make the unit suitable for packaging lines, gantry axes, and material-handling stations.
At standstill, the motor can sustain a continuous torque of 13.5 Nm without exceeding its thermal rating, giving stable force for static loads. For rapid accelerations, it can reach a peak of 41.0 Nm, allowing the axis to overcome inertial or frictional spikes during indexing. The dynamics are moderated by a rotor inertia of 2.49 × 10⁻³ kg·m², so speed changes remain predictable during servo tuning. Electrical demand at rated stall is 11.0 ARMS, and the windings accept a supply in the 240–480 V AC class, letting the same frame connect to mid- or high-voltage drives. Because the unit is supplied without a brake, braking energy must be managed by the drive or external mechanics.
Mechanical integration is aided by a body that measures 142 mm square, so it fits into standard frame mounts while leaving space for cooling airflow. Overall mass is 13.0 kg, adding stiffness to the axis structure. Cabling exits through a right-angle orientation, and the power leads terminate in a 6PP 6-pin connector, which can simplify routing where clearance around the motor is limited. Output torque is transmitted through a shaft with a closed keyway and fitted key, and the four-stack lamination core supports the magnetic circuit. This arrangement helps the motor couple securely to driven components without requiring unusual mounting changes.
