can utilize low wind speeds
The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from the energy carried in the wind. The turbine consists of a number of curved aerofoil blades mounted on a vertical rotating shaft or framework.
Georges Jean Marie Darrieus died in 1979.

Georges Jean Marie Darrieus was born in 1888.
The rotor in a DC motor rotates because the magnetic field in either the rotor or the stator is constantly changing. If it is a brush type DC motor, then the rotor field changes as the rotor moves to a new position on the commutator. If it is a brush-less type DC motor, then there is some circuitry associated with the stator that changes the stator field.
The only motor associated with a transformer is an on-line tap changing mechanism motor! So your question doesn't really make any sense!
Because there is no current flowing in the rotor, and thus there is no magnetic field in the rotor, and thus there is no torque between the rotor and the field.
Define cost leadership strategy and relate this strategy with Porter's Five Forces of CompetitionExplain rubins restaurant how the Company implement this strategy and what are the advantage and risk associated?
What is a rotor?
the blade is called rotor bladesThe rotor blades on top are called Main Rotor Blades, because they are the main source of lift for the helicopter. The smaller rotor blades on the tail are called Tail Rotor Blades.
A primary advantage associated with holding a diversified portfolio of financial assets is the reduction of risk. The relevant risk a particular stock would contribute to a well-diversified portfolio is the stock.
