Product Description

Low Speed 3-Phase Brushless Permanent Magnet Generator For Hydro Turbine

Applications

Driven by Wind Power --------Wind turbine

Driven by Water Power ------- Hydro generator

Driven by Belt with Motors

Driven by Motor

Product advantages

The wind power permanent magnet generator can last for 20 years, ensuring high speed operation for 365 days a year. It uses a multi-pole design to increase the frequency and efficiency of the rectifier and inverter. And we can also customize different current, voltage, speed, power and frequency generators according to the needs of different customers.

Product description

Permanent magnet generator can be driven by wind turbine, it is 3-phase ac voltage, low rpm, high efficiency.

The magnet is NdFeB, use SKF bearing. Permanent magnet generator can be power efficiencily within complex environment, we can according to your requirements to customized.

Product core selling point

The permanent magnet generator mainly uses rare earth neodymium iron boron permanent magnet to ensure the reliability and stability of magnetic power generation. In the transmission process, the direct drive method is adopted, and the gearbox is not used, which reduces the energy loss during power generation. To ensure the utilization of wind power. It has excellent heat dissipation performance and can increase the temperature of the fan to increase the service life of the product

This canal flows day and night – I never thought it could make money. After Greef installed the system, it runs by itself. Every day I check my phone to see how much electricity was generated and how much I earned. I'll recover my investment in less than a year, and after that it's pure profit.

Since installing this variable-pitch wind turbine, the battery hasn’t run low again. Before, I used to worry whenever we had consecutive overcast days and light winds in the winter, but now it can even charge the battery in low winds. Best of all, it doesn’t suddenly start screeching during gusts, so it doesn’t disturb my family’s sleep. The installer also mentioned that variable-pitch turbines are easier to calibrate than fixed-pitch ones. I give it five stars!

“I built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
