Product Description:
The PMA11A-00100-01 is a brushless servo motor produced by Pacific Scientific for the PMA Brushless Motors series. Intended for precision positioning in industrial automation, it converts electrical energy into regulated rotary movement so machine tools, conveyors, and small robotic joints can follow programmed motion profiles. Its compact form factor allows integration in equipment where space and thermal budgets are limited, and the brushless construction eliminates commutator wear, supporting rapid speed modulation without maintenance downtime.
Mechanically, the motor can sustain a continuous stall torque of 0.26 Nm, letting it hold light loads without overheating, while its peak capability rises to 1.4 Nm for short acceleration bursts. The low rotor inertia of 0.012 ×10⁻³ kg·m² promotes fast reversals with minimal overshoot. Power reaches the windings through a 6PP (6-Pin Power) connector mounted in a Right-Angle orientation so cables exit parallel to the mounting face. A smooth shaft eases coupling to precision gearheads, and the built-in oil seal keeps lubricants away from the resolver cavity. Because the unit is supplied without a brake, static holding must be managed by the drive or an external locking device.
The square housing measures 55 mm on each side, and the stack length code of 1 keeps the package short for inline installations. With a mass of 1.2 kg, it adds little moving weight to lightweight gantries. Feedback is supplied by a resolver, delivering absolute position data even in electrically noisy environments. The winding draws a nominal stall current of 1.3 ARMS and is insulated for bus voltages up to 240 V AC; these values define the thermal envelope and drive compatibility. Together, the compact geometry, light mass, and resolver feedback make the motor suitable for applications where current margins are tight but accurate servo performance is required.
