Product Description:

The PMA67S-11100-00 is a brushless servomotor built by Pacific Scientific within the PMA Brushless Motors series. As a rotary actuator, it converts drive current into controlled mechanical torque for positioning duties in packaging, material-handling, and other closed-loop motion axes on automated machinery. The unit combines feedback, power, and holding-brake functions to form one integrated drive element that streamlines cabinet layouts. Its resolver sensor interfaces directly with digital drives for velocity and position loops.

At the core of its performance is a continuous stall torque of 42.0 Nm, allowing the axis to support load without overheating during low-speed or static operation. When rapid acceleration is required, the motor can reach a peak torque of 133 Nm, supplying short bursts of force for indexing moves. Dynamic behavior is moderated by a rotor inertia of 10.9 x 10^-3 kg·m², which balances quick response with stable speed regulation. The winding nominal stall current is 22.0 ARMS, so the drive electronics must sustain that value during worst-case holding conditions. The three-phase windings are rated for 240 to 480 V AC, allowing the motor to connect to standard medium-voltage servo amplifiers without additional transformers.

For static holding, the integrated 24 V brake secures the shaft whenever power is removed. Field wiring is simplified because both feedback and power exit the housing in a right-angle orientation, and the supply enters through a 6-pin power connector. A closed keyway shaft delivers positive torque transmission, while the square 190 mm body and stack length code 7 establish the mounting footprint. The motor has a mass of 42.0 kg, which should be considered when sizing support hardware.
