Product Description:
The PMA45N-01100-00 is a brushless servomotor from Pacific Scientific and belongs to the PMA Brushless Motors series. It is built for closed-loop positioning and speed regulation in industrial automation cells, where stable feedback helps the drive maintain accurate motion under changing load conditions. The motor uses a resolver for rotor position feedback, and the smooth shaft supports direct coupling to gearboxes or driven machine elements without the added complexity of keyed hardware. Its square 115 mm body frame and stack length code 5 allow it to fit machinery layouts that need a compact servo with a consistent mounting envelope. This format suits indexing tables, packaging axes, and other systems that rely on repeatable rotary motion.
The motor delivers a continuous stall torque of 10.2 Nm, allowing it to hold a constant load at zero speed without losing control. Peak torque reaches 36.8 Nm for short acceleration and deceleration events, which helps when the axis must overcome inertia during rapid indexing. To produce this output, the windings draw a nominal stall current of 3.8 ARMS and are intended for a drive in the 240–480 V AC class. Low rotor inertia supports responsive speed changes during reversing moves and short settling times after command changes. These electrical and torque values suit axes that need steady holding force together with brief overload capability.
An integrated 24 V brake holds the shaft when the drive is disabled, which is useful on vertical axes or any application that must resist drift during a power loss. Power conductors exit through a right-angle 6PP connector, helping reduce clearance requirements where cabinet or machine depth is limited. The motor has a mass of 10.4 kg, which matters when the axis is mounted on a moving carriage or robot arm. The connector orientation keeps the cable exit close to the housing and helps maintain a tidy routing path around guards, covers, or adjacent components. In applications with moving structures, the motor mass also affects axis balance and support selection.
