Package of 10 motors and 10 wind turbines. The Sci-Supply SS8619 miniature motor and wind power turbine demonstration set consists of a miniature motor with 12" connecting wire leads. The motor operates on voltages of 1.5 - 3.0V DC. The motor doubles as a Wind Power Turbine Demo by attaching the included red turbine to the motor. It can produce dc power using the wind (typically teachers will utilize a fan). Gives students an insight into DC motors and provides for an understanding of the principles involved in wind energy production.
