Breakdown of the Model Name (Part Number) Understanding the nomenclature helps identify the specific electronic characteristics: * **M:** Motor (Component type). * **2:** A2 Series (Advanced functionality series). * **AS:** Low Inertia (High responsiveness for fast starts/stops). * **1:** Input Voltage (220V AC). * **A4:** Power Rating (400W). * **12:** Frame Size / Dimensions. * **R2:** Shaft Type / Keyway configuration. --- ### 3. Key Electronic Features #### High-Resolution Encoder The motor is equipped with a **20-bit optical encoder**. This allows for extremely smooth rotation at low speeds and incredibly precise positioning, essential for CNC machinery and semiconductor manufacturing. #### Low Inertia Design The "AS" designation indicates a low inertia rotor. This means the motor can accelerate and decelerate much faster than medium or high inertia motors, making it ideal for high-cycle-rate applications like packaging or pick-and-place robots. #### Electromagnetic Integration The motor utilizes high-grade permanent magnets and high-density windings to ensure a high torque-to-size ratio, reducing the overall footprint of the machine. #### Connectivity and Protection * **Power Connectors:** Specialized circular connectors for industrial durability. * **Thermal Protection:** Integrated sensors to prevent winding burnout during overloads. * **IP65 Rating:** The housing is electronically sealed to prevent liquid coolants or dust from interfering with the internal stator and rotor. --- ### 4. Compatible Drive System To operate this motor, it must be paired with an AC Servo Drive, typically the **ASD-A2-0421-L/M/F/U/E** (400W driver). The drive handles the electronic commutation and PID loop control.
