… to provide energy conversion between the mechanical torque from the wind rotor turbines, (called the prime mover) and the connected 150V load. A gearless two or three bladed upwind wind turbine using a permanent magnet DC motor can be used to charge a battery for energy storage through a rectifier and a typical wind turbine configuration is given as:
However, using a low voltage DC motor as a wind turbine generator is not always a good idea for the following reasons.
- The DC motor may not be rated for continuous use and overheat.
- The motors maximum rotational speed …
… on the activities of the regulator Ofgem, to ensure that consumers were not disadvantaged. This led to a highly liberalised energy market and low energy prices. Investment in energy capacity and infrastructure was modest.
This is changing through a combination of developments in Europe and concerns about energy security and climate change.
