Product Description:
The PMA23D-00100-00 is a brushless servomotor manufactured by Pacific Scientific and supplied within the PMA Brushless Motors series. This rotary unit is intended for industrial automation axes that need precise velocity and position control without mechanical commutation. Its permanent-magnet design allows direct coupling to ballscrews, pulleys, or gearheads for packaging, semiconductor handling, or general material transfer stations.
The motor can hold a load at standstill with 2.0 Nm of continuous stall torque, indicating the sustained electromagnetic force it can develop before thermal limits are reached. A frame cross-section of 70 mm simplifies mounting to standardized servo flanges while concentrating the magnetic circuit for higher torque density. For rapid indexing or quick acceleration, the drive can supply up to 7.2 Nm of peak torque, a short-term capability that helps the axis overcome inertial or frictional spikes. Dynamic response is influenced by a rotor inertia of 0.055 kg·m² × 10⁻³, which is low enough to support tight following of command profiles without excessive overshoot. Power electronics must source a nominal stall current of 5.4 ARMS, and this value sets the continuous thermal loading on the inverter. The winding accepts up to 240 V AC maximum, matching common mid-voltage servo amplifiers used on factory floors.
Cable routing exits the housing through a right-angle connector shell, reducing bend radius requirements inside compact enclosures, while the separate power lead mates with a 6PP (6-pin power) receptacle that keeps phase conductors separate from feedback wiring. The assembly weighs 2.9 kg, which keeps the motor light enough for gantry carriages while still providing useful vibration damping. This model is supplied without a brake, so power-off holding must be provided by external mechanics or drive torque. A resolver mounted at the rear provides rotor position feedback, and a smooth shaft helps limit wear on seals or couplings. Stack length code 3 identifies the motor's electromagnetic package.
