Product Description:

The PMA67S-10100-00 is a brushless servomotor manufactured by Pacific Scientific as part of the PMA Brushless Motors series. Designed for closed-loop motion axes, it converts electrical commands into controlled shaft rotation for position and speed regulation in automated machinery. The unit ships without a brake, relies on resolver feedback for commutation and position tracking, and uses a closed keyway shaft to transmit torque to couplings or pulleys. A seven-stack stator core lengthens the magnetic path to raise torque output within the square frame.

Its continuous stall capability is rated at 42.0 Nm, which is the torque the motor can apply continuously during normal operation. For short transients, the motor can deliver a peak torque of 133 Nm, allowing it to accelerate heavy loads quickly before settling into steady operation. These torque levels are produced with a winding stall current of 22.0 ARMS, so the drive electronics must be sized to supply that current continuously. The windings are in the 240-480 V AC class, which supports connection to standard three-phase industrial mains through a matching drive. Rotor inertia is 10.9 × 10⁻³ kg·m², a moderate value that balances response time with load smoothing. The motor follows the standard mechanical outline of the series.

The external form factor is a 190 mm square, so the motor can mount directly to heavy machine plates without custom adapters. Installed mass reaches 42.0 kg, giving the housing the thermal capacity needed for continuous duty. Power is supplied through a 6PP six-pin connector, and that plug sits at a right-angle to the shaft axis so cables exit parallel to the mounting surface. This connector orientation helps keep cable routing close to the mounting surface and can simplify placement near panels or cable ducts.
