The MPF-A320P-MJ22AA servo motor from Allen-Bradley is a low-inertia, high-output food grade servo motor. It has been designed and manufactured as part of the Allen-Bradley/Rockwell Automation MPF series of industrial food-grade rotary servo motors. The voltage class for the MPF-A320P-MJ22AA food grade servo motor is 200 Volts. It uses permanent magnet technology to reduce its inertia and increase its efficiency. This servo motor fits into a 100-millimeter frame and its permanent magnet stack length is 2 inches. The rated speed of the MPF-A320P-MJ22AA food grade servo motor is 5000 RPM. The encoder that this servo motor uses is a multi-turn high-resolution encoder. This servo motor can be installed in an IP 66 or IP 67 rated enclosure that will protect it from most common industrial substances like dust, particles, and room-temperature water.

The Allen-Bradley MPF series MPF-A320P-MJ22AA food grade servo motor does not come with a built-in brake. This motor is designed to be compact and brushless and its shaft is protected by a seal that can keep moisture and particles out of the internal components of the motor. This shaft seal will eventually wear out and need to be replaced, and the compatible shaft seal replacement kit is the Allen-Bradley MPF-SST-A3B3 kit which comes with a PTFE shaft seal and with food-grade lubricant to keep the shaft running smoothly. Using shields and other protective devices on other parts of the MPF-A320P-MJ22AA food grade servo motor is recommended too, and the cables connected to this servo motor should be connected to it in a way that allows the cable to form drip loops that will keep moisture and condensation away from the connection points.
