EMG-20AFB22 Estun 2kW Servo Motor 9.55Nm Medium Inertia 20-bit Encoder
Estun EMG-20AFB22 AC Servo Motor | 2.0kW, 2000 RPM, 9.55Nm
The Estun EMG-20AFB22 is a high-capacity industrial AC servo motor designed for high-precision motion control applications. Delivering a powerful 2.0kW (2000W) of continuous power, this motor features a Medium Inertia rotor that provides exceptional stability when driving fluctuating mechanical loads. Equipped with an advanced 20-bit high-resolution serial encoder, the EMG-20AFB22 offers the smooth rotation and precise positioning required for high-end CNC and automated manufacturing.
Key Performance Advantages
- High-Resolution 20-bit Feedback: The "F" type serial encoder provides 1,048,576 pulses per revolution, ensuring ultra-smooth low-speed performance and sub-micron positioning accuracy.
- Medium Inertia Stability: Specifically balanced to handle larger load-to-rotor inertia ratios, preventing mechanical vibration and resonance in heavy-duty axes.
- Powerful Torque Output: Delivers a consistent 9.55 N*m (1,352 oz-in) of rated torque, with peak torque capabilities up to 28.6 N*m for rapid acceleration.
- High Power Density: Utilizes high-grade Neodymium-Iron-Boron (NdFeB) permanent magnets to achieve a compact frame size without sacrificing raw power.
- Industrial Durability: Features a fully enclosed, self-cooled design built to withstand the rigors of 24/7 industrial production environments.
