Internal Product Review
The PMA13B-00100-01 is a Pacific Scientific PMA brushless servomotor with a resolver and right-angle connector orientation. Continuous stall torque of 0.9 Nm and peak torque of 4.3 Nm give the motor strong low-speed control with solid overload capability. Oil-seal construction and a 240V AC max winding class make this motor a well-balanced choice for servo applications.

Product Description:
The PMA13B-00100-01 is a brushless servomotor produced by Pacific Scientific within the PMA Brushless Motors series. Designed for integration with digital servo drives, it converts commanded current into controlled rotary motion for conveyor sections, pick-and-place heads, and metering pumps. Resolver feedback from the rotor supplies position data to the controller, allowing tight velocity and torque loops that keep automated axes on their programmed trajectories. Its compact format suits machinery that needs repeatable motion without a large motor footprint.
The motor can sustain a continuous torque of 0.9 Nm without overheating, a limit supported by its thermal design and lamination stack length of 3. To deliver this torque, the windings require only 2.7 ARMS at stall, so drive and cable demands remain moderate. Electrical insulation is rated for a maximum phase voltage of 240 V AC max, matching standard single-axis amplifiers on factory floors. A square frame of 55 mm on each side keeps the package compact for multi-axis mounting plates. Power enters through a 6PP six-pin connector with a right-angle orientation, simplifying cable routing inside narrow enclosures. A smooth shaft eases coupling to precision gearheads, and the unit is supplied without a brake so external holding can be added if required.
During rapid indexing, the servo can reach a peak torque of 4.3 Nm, giving headroom for acceleration bursts before current or temperature limits intervene. Dynamic response is aided by a rotor inertia of only 0.026 × 10⁻³ kg·m², which minimizes lag when reversing direction. System weight budgets are eased because the motor weighs just 1.9 kg, and the lower mass can help reduce moving load on compact axes. An integrated oil seal guards the front bearing against coolant splash, helping the motor operate reliably in washdown or fluid-handling stations.
