Product Description:
The PMA11A-01100-01 brushless servomotor is built by Pacific Scientific for the PMA Brushless Motors series and provides closed-loop rotary actuation in industrial automation lines. As a permanent-magnet motor with electronic commutation, it converts drive current into precisely controlled shaft motion that positions pick-and-place arms, indexing tables, or small conveyors. Integrating with matched drives, the motor serves where compact, repeatable torque output is required for coordinated multi-axis systems. Its operating style suits machinery that depends on smooth starts, accurate stops, and consistent motion from cycle to cycle.
Under steady-state conditions, the motor can hold a load with a continuous stall torque of 0.26 Nm. For rapid accelerations, it produces up to 1.4 Nm of peak torque, allowing quick cycle times when paired with a suitable drive. The windings reach nominal stall torque at a phase current of 1.3 ARMS, so inverter sizing can be based on that continuous current. The winding insulation is rated for 240 V AC max, enabling operation on medium-power servo amplifiers without a step-down transformer. Despite these ratings, the assembly weighs only 1.2 kg, which helps limit reflected inertia on lightly loaded axes. A resolver mounted in the rear housing provides analog position feedback, and the smooth shaft simplifies coupling to precision gearboxes and pulleys. This combination supports stable low-speed control and repeatable response during short positioning moves.
The square frame measures 55 mm on each side, and the motor uses stack length 1 to keep the body compact. A rotor inertia of 0.012 kg·m² × 10⁻³ supports quick acceleration while maintaining stable speed control. The factory-installed 24 V brake locks the shaft when the drive is disabled, which is useful on vertical or suspended loads. Power enters through a 6PP (6-pin) connector mounted at a right angle to the body, simplifying cable routing in tight enclosures. A dedicated feedback plug is also provided, and the front bearing uses an oil seal. The connector orientation helps reduce cable bend stress near the housing and keeps the motor easier to integrate into compact machine layouts.
