The MPL series is a low‑inertia, high‑performance brushless servo motor from Rockwell Automation. It features a compact design, high torque density, and fast dynamic response. Available in 9 frame sizes (63 mm to 300 mm flange), power ranges from 0.16 kW to 18.6 kW, continuous torque from 0.26 Nm to 163 Nm, peak torque up to 278 Nm, and speeds from 1000 to 8000 rpm. It supports resolver, incremental, or absolute encoders, with optional 24 V brake and IP66 protection. Deeply integrated with Kinetix servo drives and Logix controllers, it is suitable for applications such as packaging, material handling, electronics assembly, robotics, and CNC machinery.
🔎 Core Positioning: Low‑Inertia High‑Performance Servo Motor
The core value of the MPL (MP‑Series Low‑inertia) motor lies in its low‑inertia design. The rotor mass is relatively light, enabling extremely high acceleration and deceleration (i.e., excellent dynamic response). This makes the motor ideal for applications requiring fast start/stop, frequent speed changes, and precise positioning.
Key series features are summarized below:
| Feature | Description |
|---|---|
| High Performance | Utilises innovative winding technology and neodymium‑iron‑boron rare‑earth magnets to achieve high torque density in a compact frame; torque can be up to 40% higher compared to conventional motors. |
| Extensive Selection | Available in 9 frame sizes (flange from 63mm to 300mm), multiple voltage ratings, stack lengths, and speed options, covering a power range from 0.16 kW to 18.6 kW. |
| Flexible Configuration | Feedback options include resolver, incremental encoder, and single‑turn/multi‑turn absolute encoder; optional 24V DC holding brake; connector can be rotated 180°; DIN connector available for high installation flexibility. |
| Reliable Protection | Standard IP50 protection; upgradeable to IP66 with shaft seal kit; corrosion‑resistant cables optional for harsh environments. |
| Seamless System Integration | Deep integration with Kinetix 2000/6000/5500/5700/6500/7000 and Ultra 3000 drives, PowerFlex drives, and Logix PLCs; supports real‑time Ethernet protocols such as EtherNet/IP and SERCOS. |
📝 Model Code: How to Decode the MPL Naming Convention
Understanding the naming convention allows quick identification of key motor specifications. A typical MPL model code is structured as follows (example: MPL‑A310P‑MK74AA):
