|
Safety |
Shunt Brake
capable
in winds up to 50 mph. |
|
Class 1
electrical safety rated for prevention of electrical shocks. |
|
Features |
Low start up speed due
to low cogging and resistive torque design. |
|
Gearless direct drive
low rpm generator |
|
High standard, quality
components for use in harsh and extreme environment for wind turbines. |
|
High efficiency |
|
Excellent heat
dissipation due to the winding running on the outside edge of the Aluminium alloy outer frame |
|
Low mechanical
resistance energy loss |
|
Generator is designed
using specially selected material and treated to resist corrosion and
oxidation. |
| Designed for
reliable long
operational lifetime under long-term full output. |
|
Designed with 15
to 20 years of
operation in mind. |
|
Brush-less Design (no more changing brushes every couple of years) |
|
Quiet operation even in high winds. |
|
AC output from the unit then rectified at the battery bank to reduce
energy loss in wiring. |
|
Self Furling Design for high wind over-speed protection. |
