Product Description:

The PMA24C-11100-00 is a brushless servomotor manufactured by Pacific Scientific as part of the PMA Brushless Motors series. It is built for closed-loop motion control in automated machinery where precise position and velocity regulation are required. Within a drive system, the motor converts electrical power from a matched amplifier into continuous rotary torque for conveyors, actuators, or indexing tables while the resolver mounted on its shaft returns real-time position feedback to the controller.

This model delivers a continuous stall torque of 2.6 Nm, allowing it to hold load without overheating at zero speed, and can reach a peak torque of 9.6 Nm for rapid acceleration during short duty cycles. The rotor inertia is limited to 0.072 × 10⁻³ kg·m², so speed changes occur with minimal lag and the servo loop remains responsive. The winding nominal stall current of 3.8 ARMS is the current required to achieve rated stall torque, while the winding voltage class of 240 V AC max matches the motor to standard mid-power industrial drives. The resolver sensor supplies absolute position information over the full mechanical revolution, eliminating homing procedures after power loss.

The motor includes a 24 V brake that clamps the shaft when control power is removed, preventing load back-driving on vertical or suspended axes. Electrical terminations use a right-angle orientation and a 6PP power connector, which helps simplify cable routing inside compact cabinets. A motor body square of 70 mm determines the flange pattern, so it fits easily into machines already designed around standard IEC sizes. The closed keyway shaft, fitted with its key, transmits torque without slip, and stack length code 4 sets the active core length that results in the motor’s 3.5 kg weight. No special design features are noted, so the configuration remains straightforward for multi-axis installations.
