Based on your query, the part number **M2AS1-4444-R2/CE** refers to a high-performance **Industrial Servo Motor** manufactured by **Moog**. Below is a detailed breakdown of its electronic and electromechanical specifications. --- ## Technical Specifications Overview The M2AS series is known for its high power density and brushless design, commonly used in precision automation. | Feature | Specification Details | | :--- | :--- | | **Motor Type** | Permanent Magnet Synchronous Motor (PMSM) / Brushless AC | | **Series** | M2AS (Compact High-Dynamic Series) | | **Feedback System** | Resolver (Standard for R2 designation) | | **Protection Class** | IP65 (Standard dust and water resistance) | | **Cooling** | Natural Convection | | **Certification** | CE Marked (European Conformity) | --- ## Part Number Breakdown The alphanumeric string defines the specific electronic and mechanical configuration of the motor: ### 1. Motor Frame and Stack (M2AS1-4444) * **M2AS**: Identifies the specific product line of Moog brushless motors. * **1**: Frame size. * **4444**: These digits typically represent the stack length of the internal rotor magnets and the winding characteristics (voltage/speed rating). ### 2. Feedback Component (R2) The **R2** suffix is critical for the electronic control loop: * **Type**: 2-pole Resolver. * **Function**: This is an analog electromagnetic transducer that provides absolute position feedback within one revolution. * **Advantages**: Unlike optical encoders, resolvers are extremely rugged and resistant to high temperatures and vibrations, making them ideal for heavy industrial environments. ### 3. Compliance (/CE) * Indicates that the electronic insulation, wiring, and safety features meet the **European Economic Area (EEA)** standards for safety, health, and environmental protection. --- ## Electronic Operation and Integration To function, this part must be paired with an industrial **Servo Drive**. ### Electrical Connection * **Power Leads**: Typically 3-phase AC (U, V, W) plus a ground connection. * **Signal Leads**: A separate shielded cable for the resolver signals (Sine, Cosine, and Excitation frequencies). ### Key Electronic Characteristics * **Back-EMF**: The motor generates a sinusoidal back-electromotive force, requiring a drive that can perform sinusoidal commutation. * **Thermal Protection**: Most Moog motors in this series include an integrated **PTC thermistor** or **KTY sensor** embedded in the windings to signal the drive to shut down if temperatures exceed safe limits. --- ## Applications Due to the high torque-to-inertia ratio, this motor is used in: * Robotic arm joints. * CNC machining centers. * Packaging and labeling machinery. * Aerospace flight simulation platforms.
