· exist with maintaining structural integrity and preventing blade failure. As the tip speed increases the aerodynamics of the blade design become increasingly critical. A blade which is designed for high relative wind speeds develops minimal torque at lower speeds. This results in a higher cut in speed [10] and difficulty self-starting.

The Basics of Motor Selection - Groschopp

· Speed and torque represent the output that will be required to power the application and will affect the size of the motor. A speed and torque rating is the starting point in selecting a motor once the initial constraints are determined. Size can also be impacted by minimum requirements for starting or stall torques and duty cycle.
