Product Specification

High Light low start torque air cooling motor ，aluminium alloy blade industrial motor ，coreless permanent magnet generator motor
Air Cooling Low Start Torque Motor with Aluminium Alloy Blade Material
Axial Flux Coreless Generator technical diagram
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
