The 2KW Low RPM Coreless Permanent Magnet Generator (PMG) is specially designed for vertical axis wind turbines (VAWT) and other renewable energy systems requiring high efficiency at low rotational speeds.
It utilizes advanced torque patent “Precise Coil” coreless technology for ultra-low start torque (<1N·m), ensuring excellent energy capture even in light wind conditions.
This generator is gearless and direct drive, eliminating mechanical losses and maintenance associated with gearbox systems. Built with rare-earth permanent magnets, a coreless stator, and a high-strength aluminum alloy casing, the 2KW PMG delivers smooth, efficient, and long-life operation suitable for harsh environments.
Features:
-
Torque Patent Technology: Utilizes the latest Precise Coil design to reduce cogging and eliminate hysteresis, allowing start torque <1N·m for excellent low-wind performance.
-
Coreless Disc Structure: Innovative disc-type coreless stator design minimizes weight and size while maximizing efficiency and power-to-weight ratio.
-
High Utilization at Low RPM: Optimized for low-speed wind energy capture, making it ideal for vertical axis and horizontal axis wind turbines alike.
-
Gearless Direct Drive: No gearbox = no noise, no maintenance, and higher reliability.
-
Superior Efficiency: 85% conversion efficiency with minimal mechanical resistance and energy loss.
-
Excellent Heat Dissipation: Aluminum alloy casing and open structure allow efficient thermal performance under continuous operation.
-
Long Lifespan: Designed for over 8 times the life of traditional iron-core generators, with sealed deep-groove bearings for smooth, durable performance.
-
Corrosion and Weather Resistant: Built to withstand extreme outdoor environments—ideal for wind, hydro, or marine renewable applications.
