The R&M MF09LB200-134P35067T-IP55 is a high-performance industrial AC servo motor designed for precise motion control and high torque density. With a power rating of 2.2KW (3HP), this motor is engineered to bridge the gap between standard induction motors and high-dynamic servo systems. It provides exceptional reliability in continuous-duty applications where consistent speed regulation and robust construction are mandatory. The IP55 rating ensures the motor is protected against dust and water splashes, making it suitable for standard industrial floor environments.

 

Product Technical Description

This motor features a permanent magnet synchronous design, optimized for high efficiency and low rotor inertia. The “MF” series is known for its compact frame size relative to its power output, allowing for easier integration into tight machine architectures. It operates on a 460V AC supply, typically driven by a high-performance variable frequency drive (VFD) or a dedicated servo amplifier. The internal feedback system (encoder or resolver) provides real-time positioning and speed data to the controller, ensuring precise closed-loop operation even under varying load conditions.

Country of Origin

This motor is manufactured by R&M (Robbins & Myers) or their authorized industrial production facilities in Germany or the United States (USA).

 

Application Fields

• Conveyor Systems: Synchronized transport in logistics and material handling.
• Packaging Machinery: Precise control of tension and positioning in labeling and wrapping.
• Machine Tools: Powering auxiliary axes or spindles in CNC and milling centers.
• Plastic Extrusion: Maintaining constant torque for uniform material flow.
• Textile Industry: High-speed winding and spinning applications requiring low speed-fluctuation.

Product Usage Instructions

Before installation, verify that the motor shaft turns freely by hand. Ensure that the 460V power cables are shielded and properly grounded to prevent electromagnetic interference with the feedback signals. During mounting, ensure perfect alignment with the driven load to prevent premature bearing wear caused by radial or axial stress. When commissioning the drive, perform an “Auto-Tune” procedure to match the drive’s current loop and velocity loop gains to the motor’s specific electrical characteristics. Periodic maintenance should include checking the cooling fins for dust buildup to prevent overheating.

 

Common Questions & Answers (Q&A)

Q: Can this motor be run directly across the line (DOL)? A: No. As a permanent magnet servo motor, it must be operated using a compatible AC Drive or Servo Amplifier to control the phase commutation and prevent damage.

Q: What is the benefit of the IP55 rating for this motor? A: IP55 protection allows the motor to operate in environments where there is airborne dust and occasional moisture (like light washdowns), though it should not be fully submerged.

Q: Does the motor include an internal brake? A: This specific model code (MF09LB200) usually denotes a standard shaft; however, check for a “B” or “K” suffix in the extended part number if an integrated electromagnetic holding brake is required.

Q: How do I troubleshoot a “Motor Over-Temperature” fault? A: Check that the ambient temperature is below 40°C and ensure the cooling fins and fan are clean. Also, verify that the motor is not being operated beyond its rated current for extended periods.
