Allen-Bradley MPL-B420P-MJ72AA Brushless Servo Motor

Allen-Bradley MPL-B420P-MJ72AA is an MP-Series MPL low-inertia brushless AC servo motor rated for 460 V and 5,000 rpm. The 115 mm frame size (Frame Size 4) and 50.8 mm stack length (Stack Length 20) yield a compact yet high-speed package, with a weight around 4.3 kg. It uses a multi-turn high-resolution absolute encoder (1024 sin/cos) for precise position feedback, and comes with a keyed shaft extension, SpeedTEC DIN connectors, a right-angle 180° rotatable quick-connect, IEC Metric mounting, and free mounting holes (Type FF). The motor delivers continuous torque of about 4.74 Nm and peak torque up to 13.5 Nm, with a rated power of 1.9 kW and a maximum speed of 5,000 rpm. Brake option: No brake. This combination supports precise, high-speed rotary motion in automated systems where compact size and reliable feedback are essential.
