Unleash the full potential of our state-of-the-art Three-phase Asynchronous AC Fan Electric Motor, an engineering marvel tailored for the rigorous demands of animal husbandry. Crafted with precision to conquer the toughest agricultural environments, this motor promises unwavering efficiency and dependability, ensuring your operations run smoothly and effortlessly.
This single-phase asynchronous motor, part of our specialized agricultural motor series, is designed for demanding ventilation applications in livestock farms, particularly in enclosed environments like pig farms where stringent hygiene standards are required. Its durable die-cast aluminum housing enhances heat dissipation and provides superior corrosion resistance, making it ideal for continuous operation in challenging conditions. Operating at 220V/50Hz or 380V/50Hz, with output power ranging from 250W to 3500W (customizable to client specifications), this motor is highly adaptable to various ventilation and air exchange systems. Built with premium domestic and international brand bearings, the motor features a high-grade stator and rotor core using national standard Y2-YE3 slot cold-rolled silicon steel sheets, which contribute to its high efficiency, low temperature rise, and reduced noise levels. The optimized design ensures smooth, quiet operation and extended durability, accommodating various performance needs across agricultural settings. Special protective treatments allow for an IP65 protection rating, safeguarding the motor against dust and water ingress to support reliable, long-lasting service in moisture-prone and dust-intensive environments. |
