Product Description

Complete Permanent Magnet Alternator for 3kW-5kW VAWT – Direct Drive, 48V/110V/220V for Wind Turbine Parts
Our VAWT Wind Turbine Generator System delivers exceptional performance with high-efficiency vertical axis wind turbine operation and low startup wind speed requirements.
Generator Overview
Our Permanent Magnet Generator (PMG) is specifically engineered for vertical axis wind turbines (VAWT), offering superior performance in low to medium wind speed conditions. With a high-efficiency design and robust construction, this generator ensures reliable energy conversion, minimal maintenance, and long-term durability in both on-grid and off-grid wind power systems.

General Design Features


-Type:Three-phase AC Permanent Magnet Synchronous Generator (PMSG).
- Structure:Outer rotor design (preferred) to allow direct connection to the turbine rotor, providing smooth rotation.
- Excitation: High-grade Rare Earth Magnets (e.g., NdFeB) for high efficiency and no external excitation current required.
- Torque Characteristics: Ultra-low cogging torque (coreless designs can achieve near-zero start-up torque) to ensure generation starts in light breeze conditions (as low as 2.5 m/s).


Key Parameter Descriptions

Electrical Parameters

- Output Voltage:The generator outputs raw three-phase AC. This is typically rectified to DC (e.g., 48V, 96V, 220V, or 380V DC) by the charge controller for battery charging or grid connection.
- Frequency: Variable frequency, proportional to the rotor speed (e.g., 0–50 Hz).
- Efficiency: Typically >90% at rated load for PMSG designs.
