Product Description:

The PMA43P-10100-00 is a brushless servo motor produced by Pacific Scientific within the PMA Brushless Motors series. Designed for closed-loop motion axes, it converts drive current into controlled mechanical rotation for positioning, conveying, or indexing stages used in industrial automation cells. It pairs with matched digital drives to deliver repeatable torque without the maintenance associated with brushed designs, while feedback signals return to the controller for tight velocity and position control across starts, stops, reversals, and steady-speed operation. This makes the motor suitable for automated equipment that requires accurate rotor control during frequent cycle changes and short move profiles.

The motor has a continuous stall torque of 6.1 Nm, which indicates the static load it can hold without overheating under continuous stall conditions. During acceleration or transient overloads, it can reach a peak torque of 21.7 Nm, providing extra output for rapid indexing and short bursts of higher demand. The square 115 mm frame fits IEC-compliant mounting patterns, and the power and feedback connectors exit in a right-angle orientation to reduce axial space requirements. Power is supplied through a 6PP six-pin power connector that supports quick connection. A closed keyway shaft with the key fitted transmits torque to couplings, the motor is supplied without a brake, the stack length code is 3, and a resolver sensor supplies position feedback.

Dynamic response is supported by a rotor inertia of 0.52 kgm² × 10⁻³, a value that helps the motor change speed quickly while still smoothing torque ripple. Total mass is 7.6 kg, which gives the housing enough thermal mass for steady operation without making the unit excessively heavy. Electrically, the windings draw a nominal stall current of 5.4 ARMS at locked rotor, and they are insulated for the 240-480 V AC voltage class. This voltage class allows operation with compatible three-phase servo drives used in common industrial power systems.
