PMA45R-01100-00

Product Description:

The PMA45R-01100-00 is part of the PMA Brushless Motors family from Pacific Scientific, designed for tough and precise jobs where motion matters. This is a three-phase AC servo motor that uses natural cooling—no built-in fan—so there’s less noise, and less moving parts to worry about. Power output comes at 1.0 kW, while operation keeps steady with rated voltage at 220 V AC. The frame size sits at 45 mm, making it good for machines where not much space is free. With a rated torque of 3.18 Nm, this motor won’t hesitate to keep things turning steady.

The design uses an incremental encoder at 2500 PPR, so feedback stays sharp no matter the task. Rated current at 5.0 A makes this motor fit for medium-duty uses, not too big and not tiny either. Maximum torque clocks in at 9.54 Nm, which helps when extra push is needed during cycles or start-ups. Spin speed is 3000 RPM at the top end, meaning operations that depend on fast moves get what’s needed. Protection gets handled too with the IP65 rating, standing up well against dust and the odd water spray—plenty good for places that are never fully clean. The unit’s mass comes at 2.5 kg, easy enough to handle but sturdy for mounting without feeling flimsy.

The cooling stays passive—no maintenance or filters to swap. This makes the PMA45R-01100-00 a direct fit for settings like pick-and-place machinery, robotics, and CNC equipment that work long hours. The combination of solid torque, speed, and voltage means performance stays steady even through busy shifts. In automation benches and industrial lines, the IP65 case keeps out grime, and the compact shape slips into frames where something bigger would be a hassle.
