Product Description
The Allen-Bradley MPM-B1151F-MJ74AA Kinetix servo motor, designed for medium inertia applications, is a brushless AC synchronous motor compatible with Kinetix servo drives like the 5500, 5700, 6200/6500, 6000, 300/350, 2000, and 7000 series. Ideal for printing, web handling, converting, and automotive applications, it features a 1 mm frame size, one magnet stack, a 4000 RPM rated speed, and a 1024 sin/cos absolute single-turn Hiperface encoder for precise control. It includes a keyed shaft, a rotatable SpeedTec DIN connector for line voltage, and a 24 VDC holding brake. Performance specifications include a 0.75 kW rated output, 2.18 N-m continuous stall torque, 6.6 N-m peak stall torque, and 0.00065 kg-m2 rotor inertia. While initially rated IP50, it can achieve IP65 with appropriate seals and cables. This motor supports Smart Motor Technology for easy network identification, operates at 460V with a 3000 RPM base speed, and offers a multi-turn absolute encoder. It withstands 0-40C temperatures and features IP65/67 protection, a square mounting flange with a 115mm BCD, and vibration resistance. The feedback is available in a multi-turn absolute encoder form with Hiperface protocol, offering high-resolution absolute position feedback in 4096 turns without a battery.
Is Your Device Showing These Signs?
The Allen Bradley MPM-B1151F-MJ74AA servo motor commonly experiences issues such as resolver feedback failures, requiring resolver replacement or recalibration. Overheating due to inadequate cooling or excessive load is fixed by addressing fan malfunctions, optimizing load parameters, or replacing thermal protection devices. Winding insulation breakdown, leading to short circuits, necessitates motor rewinding or complete replacement. Bearing failures, indicated by excessive noise or vibration, are resolved through bearing replacement and proper lubrication. Communication errors with the drive system are corrected by verifying encoder signals, checking cabling integrity, and updating firmware.
