High Light 220V Low Rpm Dynamo Generators ，3000 Watt Low Rpm Dynamo Generators ，5000 Watt Low Rpm Dynamo Generators
3000 Watt 5000 watt 220V Low start torque low rpm dynamo generators for sale
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 <0.3N.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
