Product Description:
The PMA43Q-Y0100-02 is a brushless servo motor produced by Pacific Scientific for the PMA Brushless Motors series. This permanent-magnet actuator supplies rotary motion for indexing tables, gantry axes, and coordinated pick-and-place heads, and it is intended for use with a compatible servo drive. Designed for direct coupling to precision gearboxes or belt drives, it converts drive current into repeatable torque with the low maintenance expected of a brushless motor. That arrangement suits repetitive positioning tasks where stable torque delivery and predictable response matter. The motor does not include an integral brake, so applications that must hold a load at standstill need an external locking device or another holding method.
Continuous stall torque is 6.1 Nm, giving the motor steady low-speed output when adequate cooling is available. For short acceleration demands, the peak torque reaches 21.7 Nm, which helps the axis overcome inertia during rapid starts and direction changes. The winding draws 7.4 ARMS at stall, so the selected drive must match the motor current demand without exceeding thermal limits. The motor is intended for operation from a supply range of 240–480 V AC, making it suitable for common industrial power systems. Rotor inertia is 0.52 kg·m² × 10⁻³, which supports responsive servo tuning without making the drive train overly sensitive to load disturbances.
The housing measures 115 mm on each side and uses stack length 3, so it fits compact machine frames while still providing a rigid mounting face. Total mass is 7.6 kg, which keeps the motor manageable for installation on moving axes and fixed stations alike. Power is connected through a 6PP six-pin connector, and the feedback leads use a separate circular header. Both connections are arranged in a right-angle orientation to the shaft axis, which helps route cables along guards or side panels. Rotor position feedback is provided by a Resolver, offering robust signal transmission in electrically noisy environments and steady feedback for closed-loop motion control.
