Internal Product Review
The PMA12A-10100-00 is a Pacific Scientific PMA brushless servomotor with a resolver and right-angle connector orientation. Continuous stall torque of 0.6 Nm and peak torque of 2.9 Nm support stable servo response with strong short-term acceleration. A closed-keyway shaft with fitted key simplifies coupling, making the motor a very capable choice for precise motion applications.

Product Description:
The PMA12A-10100-00 is a brushless servo motor produced by Pacific Scientific for the PMA Brushless Motors series. This model serves as a compact rotary actuator that integrates with a matched drive to provide closed-loop speed and position control in automated cells. By turning electrical commands into regulated torque and velocity, it supports precise movement of light mechanical loads found in labeling heads, vision-guided end effectors, and small conveyors across packaging or electronics assembly lines. Its compact format also helps it fit tightly spaced axes where low moving mass and accurate response are important.
Continuous stall torque is 0.6 Nm, which is the maximum steady load the stator can hold without excessive thermal rise, while a peak capability of 2.9 Nm provides short bursts for fast indexing cycles. These values are achieved with a winding that draws only 1.3 ARMS at stall and is insulated for supplies up to 240 V AC. The motor has a square frame dimension of 55 mm and a stack length of 2, which balance footprint against available magnetic area. A rear-mounted resolver returns rotor position, and the motor is supplied without a brake, making it suitable for drive-torque holding systems that rely on external locking when power is removed.
The rotor’s moment of inertia is just 0.019 × 10⁻³ kg·m², so commanded speed changes translate into rapid mechanical response with minimal overshoot. Total mass is limited to 1.5 kg, which eases installation on moving carriages or robot wrists. Cabling exits through a right-angle housing, reducing the clearance needed behind the motor, and power is delivered by the dedicated 6PP six-pin connector that aligns with standard Pacific Scientific harness kits. This arrangement also helps where cable routing must stay close to the housing during repeated motion. The motor uses a closed keyway shaft for positive coupling, and no special design modifications or additional seals are included.
