Product Overview

Conventional generators typically depend on substantial iron cores, which contribute to magnetic resistance and core losses that reduce overall efficiency. Our innovative disc-type design guides magnetic flux along the axial direction, completely eliminating the iron core from the system.

By removing the iron core, our design significantly minimizes magnetic resistance and core losses, leading to improved efficiency and performance in generator operation.

Key Features
  • Torque Patent Technology: Utilizes cutting-edge "Precise Coil" system, eliminating hysteresis and gear notch effects with exceptionally low starting torque of less than 0.3 N*m
  • Original Structure: Disc coreless design reduces overall size and weight for more compact and lightweight devices
  • Higher Utilization: Special coreless motor technology overcomes traditional limitations at lower speeds in wind energy applications
  • Higher Reliability: Superior power-to-volume and power-to-weight ratio with lifespan eight times longer than typical motors
  • Gearless Direct Drive: Low RPM generator provides smooth, efficient energy conversion without gear wear and noise
  • Quality Components: Built to withstand harsh and extreme environments in wind turbine operations
  • High Efficiency: Minimal mechanical resistance reduces energy losses and improves performance
  • Exceptional Heat Dissipation: Aluminum alloy outer frame with specially designed internal structure maintains optimal operating temperatures
  • Customizable: Clients can specify voltage, speed, power, and frequency parameters
  • H Class Insulation: Vacuum pressure impregnation ensures superior electrical insulation and reliability

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 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.”
