Allen-Bradley MPM-B1152T-MJ74AA AC Servo Brake Motor

The Allen-Bradley MP-Series MPM-B1152T-MJ74AA is a medium-inertia 460 V AC rotary servo motor built in a 115 mm frame and rated for up to 6,000 rpm, designed for precise closed-loop control in automated systems. It includes a 24 V DC brake for controlled stopping and a multi-turn high-resolution encoder that provides absolute feedback, enabling accurate positioning across cycles. The motor offers a keyed shaft extension, seven SpeedTEC DIN connectors, and a right-angle, 180° rotatable quick-connect mounting option, with IEC metric mounting holes (Type FF) for flexible installation. For harsher environments, it carries an IP65/IP67 enclosure rating, supporting reliable operation on factory floors and in automated machinery. Documented as part of Rockwell Automation’s MP-Series, this servo motor is suited for machine-drive applications that demand compact form factor, integrated braking, and precise feedback to drive high-precision motion control.
