MPL-A420P-SJ72AA

The MPL-A420P-SJ72AA Low Inertia Servo Motor by Allen-Bradley is a low-inertia servo brushless motor in the MP low-inertia motors series with 200V AC operational voltage and 5000 rpm base speed designed to deliver higher torque in a high-performance motion system. The motor features a high torque-to-size ratio with low-rotor inertia and a magnetic stack length of 2 inches. It has an operational voltage of 200V AC, with a 2kW rated motor output, and a maximum motor speed of 5000 rpm. The MPL-A420P-SJ72AA has a single-turn, high-resolution encoder with 8-15-bit resolution (256-32768 counts per revolution), and with either the TTL, open collector, SSI, or the push-pull outputs, with reverse polarity protection. It has a maximum stall torque of 0.2N•m (90lb•in), with a 0.00026Kg-m2 (0.0023lb-in-s2) rotor inertia, and a base speed of 5000 rpm.

The MPL-A420P-SJ72AA motor has a bearing fatigue life of 20,000 hours with a radial load force rating of 78Kg (172lb) at 1000 rpm, 51Kg (112lb) at 3500 rpm, and of 49Kg (99lb) at 5000 rpm maximum motor speed. It also has an axial load rating (with zero radial force) of 51Kg (112lb) at 1000 rpm, 30Kg (66lb) at 3500 rpm, and 25Kg (55lb) at 5000 rpm. The MPL-A420P-SJ72AA has a 115mm frame size, with 50.8mm magnetic stack length, and it is designed with a keyless shaft extension enclosure. The motor is installed using an IEC metric flange mount option with free mounting holes, and a circular, right angle, and 180o rotatable DIN connector. It has functional temperature limits of 0-40 oC (32-104 oF), at 5-95% non-condensing humidity without de-rating, and it is stored at a range between -30 and 70 oC (-22 and 158 oF). The MPL-A420P-SJ72AA weighs approximately 4.3Kg (9.4lb), and it has net dimensions of 190mm x 140.1mm x 98.3mm (7.4in x 5.52in x 3.87in).
