Product Description
 
Disc Coreless Permanent Magnet Generator

 

 

 
Product Advantages

 

 

This Coreless Permanent Magnet always being used in vertical axis wind turbine, and other generator system which requests very low start torque and low rated rotate speed, low start wind speed, low weight and small size.

 

1 Torque Patent Technology: use newest “Precise Coil” technology. No hysteresis and gear notches effect make the start torque very low <0.1N.M
2 Original Structure: use disc coreless motor to take place traditional motor makes it less volume and weight.
3 Higher Utilization: use special coreless motor technology to eliminate the use bottlenecks of lower speed wind energy.
4 Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.
5 Gearless, direct drive, low RPM generator.
6 High standard, quality components for use in harsh and extreme environments for wind turbines
7 High efficiency and Low mechanical resistance energy loss
8 Excellent heat dissipation due to the Aluminum alloy outer frame and special internal structure.

My farm is 30 kilometers from town, and connecting to the power grid would cost a fortune. Three years ago, I installed a solar panel system with a battery bank. It was sufficient during spring, summer, and fall, but in winter, we often had a week of consecutive overcast days—and the batteries would run out in just three days. Last year, I decided to add a variable-pitch wind turbine, connected it to the AC coupling port of the Deye inverter, and set up a hybrid solar-wind system. Throughout the entire winter, the battery level never dropped below 45%, and I never had to work in the dark again. The Deye app allows me to monitor both the solar and wind turbine data simultaneously, and the transition between them is so smooth it’s almost imperceptible. Relying solely on solar power during winter on a Nordic farm is a gamble. Only by combining a variable-pitch wind turbine with a Deye inverter—creating a wind-solar hybrid system—can you get through the winter with peace of mind.

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 run a small dairy farm in northern Norway, far from the power grid. A few years ago, I installed solar panels and a Deye inverter, but the solar system basically stops working in winter, and the diesel generator was costing me a fortune. This year, I added this variable-pitch wind turbine and connected it to the Deye inverter for a hybrid solar-wind system, and we haven’t had a single power outage all winter. This wind turbine starts up at low wind speeds of just 2–3 on the Beaufort scale. During blizzards, the blades automatically pitch down to slow the turbine, preventing runaway speeds, and it’s much quieter than my neighbor’s fixed-pitch model. The Deye inverter’s switching logic is smart—it prioritizes solar power when available, and automatically switches to the wind turbine when solar output drops. It’s all clearly visible on the app. Now, the diesel generator is practically idle. Wind and solar backing each other up—that’s true off-grid freedom.
