Technical Description: Panasonic MDME302GCG Servo Motor
The MDME302GCG is a robust, high-power AC brushless servo motor from the MINAS A6 Series. With a rated output of 3.0 kW, this motor is a Medium Inertia model, specifically engineered to provide stable and powerful motion control for applications with high-load imbalances or heavy mechanical stages. It is the premier choice for large-scale gantry systems, heavy-duty CNC machinery, and high-capacity industrial robotics where constant torque and high-resolution feedback are non-negotiable.
High Torque and 23-bit Resolution
The MDME302GCG is equipped with an industry-leading 23-bit absolute/incremental encoder, providing 8,388,608 pulses per revolution. This ultra-high resolution ensures exceptional path-following accuracy and ultra-smooth rotation at low speeds. The «G» winding indicates that this is a 400V class motor, designed for international power standards and high-efficiency operation. Its high torque density allows it to deliver a rated torque of 19.1 N·m in a relatively compact frame size.
