MPL-B640F-MJ72AA

The MPL-B640F-MJ72AA AC servo motor is an MPL series low inertia rotary servo motor from Allen-Bradley. It comes with an armature voltage rating of 460 Volts AC and a small frame size of 215 millimeters or 8.46 inches. The magnet stack of the permanent magnets used in this servo motor is 4 inches. This AC rotary servo motor is characterized by its low inertia and high torque density that are contained in a small package. The MPL-B640F-MJ72AA servo motor does not have an integral holding brake and it has a rated rotor inertia of 0.004 kilograms per square meter. It weighs about 26.8 kilograms. The MPL-B640F-MJ72AA servo motor comes with a nominal rotor speed rating of 2000 RPM which can reach up to 3000 RPM at full power. This compact and low-inertia servo motor generates a continuous torque of 36.7 N-m and up to 72.3 N-m of peak stall torque. Its continuous current and peak current ratings at a stall are 32.1 Amps and 65 Amps, respectively.

The Allen-Bradley MPL-B640F-MJ72AA MPL series low inertia servo motor comes with a Hiperface multi-turn absolute encoder feedback system. The feedback signal shape is Sinusoidal with 1024 sin/cos resolution per revolution. The feedback signal from the motor is fed to the connected servo drive via the SpeedTEC-ready DIN connectors on the motor. The circular SpeedTEC DIN quick connect connectors on the MPL-B640F-MJ72AA servo motor allows for flexible connection orientation with their ability to provide 180 degrees of rotation. The connectors are UL-Listed and RoHS certified. The shaft of the motor has a shaft key that supports mechanical connections to the motor. This servo motor can be mounted using an IEC metric mounting flange with Type FF free mounting holes. The MPL-B640F-MJ72AA servo motor does not come with a shaft seal, but an optional IP 66 rated shaft seal kit can be ordered as an add-on and installed.
