Key Advantages
- 400V High-Voltage Optimization: Specifically designed for 400V power grids, this motor allows for lower current draw and reduced heat generation compared to 200V counterparts, making it more efficient for large-scale industrial installations and long cable runs.
- Superior Medium-Inertia Stability: The EMJ series provides a better inertia ratio for mechanical loads like ball screws and belt drives, resulting in significantly reduced vibration and shorter settling times during high-speed positioning.
- High-Resolution 20-bit Precision: Equipped with a serial encoder providing over 1 million pulses per revolution, ensuring sub-micron accuracy and ultra-smooth rotation even at extremely low speeds.
- Rugged Industrial Durability: With an IP65 rating and factory-installed oil seal, this motor is built to withstand the rigors of the factory floor, including exposure to dust, humidity, and oil mist.
