Allen‑Bradley MPM-B1652F-MJ74AA – Compact MP‑Series MPM Servo Motor for Precise, Fast Motion on Kinetix Drives

The Allen‑Bradley MPM-B1652F-MJ74AA is part of the MP‑Series MPM family — a compact, low‑inertia AC servo motor designed to pair seamlessly with Kinetix drives in packaging, indexing, cartoning, and light robotic axes. From my experience, this model hits a sweet spot for fast point‑to‑point moves where you want crisp response without overshoot, and where panel space is tight. You might notice that it typically integrates quickly thanks to the built‑in motor database in modern Kinetix platforms, which shortens commissioning time.

The “MJ74AA” build suffix denotes a specific factory configuration of feedback/shaft/brake options. Rockwell uses these codes to define exact build features for a given motor. If you’re replacing an existing unit, matching the full string ensures drop‑in mechanical and electrical compatibility. One thing I appreciate is how these MP‑Series MPM motors keep a consistent connector scheme, so swap‑outs are usually straightforward on the plant floor.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week when in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• MP‑Series MPM platform – Compact, low‑inertia rotor for quick acceleration and tight position control in many cases.
• Kinetix‑ready – Designed to work with Kinetix 2000/6000/6500/5500/5700 drives; motor data is typically preloaded, which speeds up tuning.
• High‑resolution feedback – Factory‑configured absolute feedback (build dependent) for stable low‑speed performance and reliable homing‑free startups.
• Industrial sealing – Rugged housing and shaft‑seal options suited to general industrial environments; helps reduce ingress of dust and moisture.
• Serviceability – Connectorized power/feedback interfaces make changeouts faster during planned downtime.
• Use cases that fit – Multi‑axis cartoners, labelers, pick‑and‑place gantries, small indexing tables, feed rollers, and light duty servo axes.

Technical Specifications

Note: Specifications can vary slightly by exact build code (e.g., shaft, brake, and feedback options encoded in “MJ74AA”). If you share the existing nameplate photo or drive part number, I can confirm a one‑to‑one replacement.

Related or Supporting Products

• Allen‑Bradley Kinetix 5500 (2198‑Hxxx) – 230 VAC class; common match for MPM motors; compact, dual‑port EtherNet/IP. Great for multi‑axis packaging lines.
• Allen‑Bradley Kinetix 5700 (2198‑Hxxx) – Higher power and integrated safety; better when axes count and throughput increase.
• Allen‑Bradley Kinetix 2000 (2093‑ACxx) / 6000/6500 (2094‑xx) – Legacy platforms often found with MPM installations; we can match cable sets and feedback options.
• MPM‑B1652F variants – Different suffixes (e.g., MPM‑B1652F‑MJ72xx or MJ7Axx) typically denote feedback (single vs multi‑turn), brake presence, or shaft options. Useful for direct replacements.
• MPL Series (MPL‑Bxxxx) – Similar MP‑Series low‑inertia motors; alternative when you need different torque/speed curves or mechanical envelope.
• MPF Series (Food‑grade) – When washdown or food packaging compliance is required; stainless features and enhanced sealing.
• Feedback & power cables – Factory‑terminated cable sets for MPM to Kinetix (lengths from 3 m to 30 m, shielded). Matching the exact connector type avoids start‑up delays.

Installation & Maintenance

• Mounting – Use a rigid, flat mounting surface; align the pilot carefully. From my experience, misalignment shows up as higher current at low speed.
• Wiring – Route motor power and feedback separately from high‑noise conductors. Bond shields at the drive end; maintain proper PE grounding.
• Cabinet & ventilation – Keep the drive cabinet within its rated temperature. The motor is fine in 0–40 °C ambient, but the drive’s cooling often dictates the real limit.
• Brake (if equipped) – Use a 24 VDC brake supply with suppression; verify brake release in the drive prior to axis enable.
• Tuning – Start with the Kinetix auto‑tune, then refine velocity/position loop gains. You might notice better settling by enabling feed‑forward after basic tuning.
• Routine checks – Inspect connectors, seals, and shaft coupling quarterly. Keep the motor exterior clean to aid heat dissipation. Confirm encoder count/rotation direction after any mechanical work.
• Safety – Lockout/tagout, verify axis torque off, and use proper lifting/handling. Never energize a braked motor without confirming brake wiring.

A maintenance manager told us this motor “dropped into our Kinetix 5500 rack, auto‑identified right away, and we were back in production in under an hour.” That tends to be the norm when the build code is matched and cabling is correct.

Quality & Certifications

• CE and UKCA conformity (typical for MP‑Series motors)
• cULus recognized
• RoHS compliant
• Manufacturer warranty policies apply; our supply warranty is 365 days as listed above

If you can share the installed drive model, desired speed/torque, and the existing motor’s nameplate photo, I’ll validate the MPM‑B1652F‑MJ74AA build and cable set so you receive a straight drop‑in replacement with the right lead time.
