Product Description:

The PMA13B-00100-00 is a brushless servomotor produced by Pacific Scientific within the PMA Brushless Motors series. Designed for closed-loop positioning and speed regulation, this motor converts electrical power into mechanical rotation for repeated motion tasks in automated pick-and-place stations, conveyors, and packaging axes. It belongs to the PMA Brushless Servomotors product type and, because it does not include an integrated brake, relies on the drive for dynamic stopping during normal operation. The smooth shaft interface simplifies coupling to gearheads or pulleys commonly used in light-duty industrial machinery.

This model supplies a continuous stall torque of 0.9 Nm, allowing steady axis holding without thermal overload. During acceleration or shock load events, it can reach a peak torque of 4.3 Nm, giving a short-term force margin of almost five times the continuous rating. Rotor inertia is only 0.026 × 10⁻³ kg·m², so commanded speed changes are executed quickly and with minimal controller effort during short indexing moves. The frame measures 55 mm square, matching the size code used across the series, and cable terminations exit through a right-angle connector that reduces required cabinet depth. A stack length of 3 increases available output without increasing the cross-section of the motor housing.

The winding set draws a nominal stall current of 2.7 ARMS from drives that supply up to 240 V AC max. Power is delivered through a 6PP six-pin connector that separates the motor phases from the resolver leads, which helps keep the signal path distinct from the power conductors. Overall mass is 1.9 kg, so the motor can be mounted on small gantries without exceeding payload limits or adding excessive moving mass. A resolver provides position feedback for the drive, and the compact connection layout supports installations where cable space is limited. The electrical ratings suit compact servo systems that need moderate torque and fast response from a small frame.
